• 2018 GMC Yukon Denali: Should I Wait for the 10-Speed or Buy a 2017 8-Speed Now? Ask TFLtruck

    2018 GMC Yukon Denali

    We have received the following question at ask@tfltruck.com from Chad S about the new 10-speed automatic transmission that is coming to the 2018 Yukon Denali. GM co-developed this transmission with Ford. Both companies say that while some designs and components are shared, each company performed its own tuning, calibration, and parts to customize the transmission for use with different engines and vehicles.

    Chad S. writes:

    I have a question about the 2018 Yukon Denali. They are giving it a 10-speed transmission as opposed to the 8-speed that it currently has. My questions are:
    – Are there massive benefits to the 10-speed? What about drawbacks?
    – Would you buy the vehicle in its first year with the 10-speed tranny?
    – As someone in the market for a Yukon Denali, Would you recommend waiting for the 2018 or shopping for a 2017 (given the changes)?

    This is a classic question: “Should I get the very latest or existing technology?”. This is why we wanted to publish it to start the discussion. Unfortunately, we have not yet had a chance to test drive a GMC Yukon or a Chevy Tahoe with the 10-speed. At this point, we have to go on the experience we have between the 2016 Ford F-150 6-speed and the 2017 Ford F-150 10-speed.

    The 10-speed in the Ford truck is seamless and smooth. It shifts gears very quickly and it’s hard to notice the shifting most of the time. The 10-speed in the F-150 delivered a small 7.5% improvement in towing fuel economy (7,000 lbs trailer), but that also included the updated 3.5L EcoBoost engine.

    The 10-speed transmission design also allows for a smoother engine Auto start/stop function when the truck comes to a stop. In general, the benefits of the 10-speed transmission are a wider gear span for quicker acceleration and more efficient highway cruising. The choice of more gears means that the engine can run within it’s optimum operating range more often.  The downsides are the additional cost and complexity of the transmission.

    Bottom line is – there will be two groups of people: those who must have the absolute latest cutting edge technology “early adopters”, and those who prefer technology that has been around longer and has a proven track record.

    GMC Yukon Denali

    We (at TFLtruck) know that the current GMC Yukon Denali 8-speed is a great full-size SUV. It’s powerful, big, and it did very well on our Ike Gauntlet™ extreme towing test.

    Personally, I am an early adopter. I cannot wait to drive the 2018 model with the 10-speed. I would lean towards waiting a little longer for the 2018 version with the 10-speed and see how it performs.

    Here is a first look at the 2018 Chevy Tahoe RST with the 10-speed automatic.

    1. Coming from someone with an F150 with the ten speed, I would by an new Expedition or a Navigator:). In seriousness just realize that the 10 speed will return better fuel mileage.

      1. Unless Ford offers the 5.0 in the Expedition/Navigator, you’re stuck with the unreliability of the Ecoboost unfortunately.

    2. @SCP: Really? Saving a few dollars a week when spending 70$ on a vehicle matters?

      When spending that kind of money on a vehicle I’d be more concerned with the ownership experience, than saving a few bucks a week on dead dino juice.

      Be sure to find a good dealer, cuz if something goes wrong, it’s ones time that adds up quickly. Or consider an LX570 if that’s in the budget. Toyota treats Lexus owners like gold.

      Technology may have improved with newer vehicles, and with it an increasing sticker price, but the ownership experience hasn’t. That’s what I’d be concerned with–just saying…

      1. Excellent points. For the average private consumer; Driving, Hauling, and Towing performance are much more important than Fuel savings. Dealer support is critical when buying Any new product.

    3. I would have to say you owe it to yourself to consider the expedition. Similar money but far better interior space and packaging. Potentially better engine performance too.

    4. so they are gonna put the 8 speed out to pasture? no point in keeping a mid grade trans in the lineup to put in a fleet/base model

      1. The 8 speed is a great transmission. It works very well with the 6.2. I have that configuration in my ’16 Sierra 1500. It’s a huge improvement over the old 6 speed auto, which I had in my ’13.

        The Ford people telling you to wait are comparing the difference between the 6 speed auto and the 10. Which is a huge improvement. I doubt the 10 will be a whole lot better than the 8 speed.

        Bottom line, if you want the current Yukon, and like the way it drives, buy it.

    5. I don’t understand the Yukon Denali. Why would I buy a rapidly depreciating domestic POS that is worthless offroad when for the SAME MONEY I could by a Land Cruiser, which will go anywhere, go 20 years before you have to do anything other than change tires, brake pads, and oil, and sell for $50K with 100,000 on it.

      1. Yeah, go with a Toyota/Lexus product if they at all have your configuration of vehicle you need. You won’t regret it.
        Otherwise, let’s all call for electric generator hybrids. Only then can an American brand have a simple enough vehicle that we can make reliable for many years. Electric motors are totally simple and reliable No transmissions is far more reliable as well as “smooth” beyond smooth. And a diesel engine being used as a generator will last a million miles easy, rather than one hooked up to a transmission.

          1. Daniel, I’ve looked into several things you have said(like I have with many others on TFL), and you tend to be on the incorrect side of arguments., to put it kindly. For your own sake, you may want to think things through for a while before writing things down. Then, you can build up credibility and everyone won’t just pass over your comments with a sigh.

            1. I have my fair share of inaccuracies, but the myth that you can get more energy out of electricity than what it took to generate it… is flat out wrong. You cannot create energy, you can only capture and convert it and there are always losses involved.

              Example, let’s say a gallon of diesel contains 100 BTUs of energy. Diesel engine is 45% efficient leaving us with 45 BTUs to play with. About 80% of that can be captured, and stored in a Lithium type battery, leaving us with about 36 BTUs. Power transmission and the electric motor are at best 90% efficient leaving us with about 32 BTUs to play with.
              Now the fun compounds. Where do you mount your electric motor? If it’s mounted to the axle, then you still have 5-10% additional efficiency losses. If you use an in-wheel motor, great, minimal additional losses, but good luck trying to get decent handling characteristics with that much unsprung weight.

              There is no easy answer to making vehicles cleaner or more efficient.

        1. Electric motors and their associated controlers are not simple, nor inexpensive. There is no reason to think that a diesel connected to a generator rather than a transmission is going to have a substantially longer life span. Generator engines wear out-just the same as they do in vehicles.

          1. yeah I am thinking there is going to be a frequency drive for controlling the electric motors. Those things are not cheap for the 100hp+ models.

            1. That’s what most current vehilces with electric motors use. Complicated and expensive. They work great though.

        2. Can we not divert every thread OT and argue over electric versus whatever? It isn’t happening any time soon. If at all. It’s also annoying to have to listen to the same crap in every comment section.

          You people that want to argue about this should have your own forum, and leave the rest of us to actually discuss the articles in question.

        3. The 8 speed is a great transmission. It works very well with the 6.2. I have that configuration in my ’16 Sierra 1500. It’s a huge improvement over the old 6 speed auto, which I had in my ’13.

          The Ford people telling you to wait are comparing the difference between the 6 speed auto and the 10. Which is a huge improvement. I doubt the 10 will be a whole lot better than the 8 speed.

          Bottom line, if you want the current Yukon, and like the way it drives, buy it.

      2. You kid yourself. The Land Cruiser is a good rig and it does hold its value well but it is nowhere near as rosy as you think. The current-gen LC is less capable off road than past generations have been. It is also loaded with electronics which inevitably reduce reliability. The engine is simply a Toyota Tundra engine. In 20 years time, you will be doing a whole lot more than tires, brakes, and oil. You’ll be doing control arms, ball joints, bushings, exhaust, wheel bearings, various sensors, and probably rust repair depending on what region of the world you live in. You aren’t going to sell this LC for $50k with 100k miles on it, either. 10 year old LC’s with 100k miles on them have asking prices around $20k. Its tremendous value, for sure…but these are also low volume rigs with a cult following. The rigs in question are also the previous generation, which in my opinion was better looking and better made.

        As to the Denali…well…it is overpriced for sure and lacks much off-road capability…but it still has a great engine with a lot more power than the LC engine, and has a more luxurious interior with more options and luxury features available.

        1. More luxurious interior? That’s highly debatable. I find GMs materials cheap, even on the Denali level. And their cluttered overall layout is just unattractive.

          A lot more power? Hardly. They’re somewhat more powerful but they also have taller gears in the rear end and GM’s trademark super soft throttle response, so they feel slower. Plus those are displacement on demand engines which are long-term reliability nightmares. No thanks. I’ll take the proven invincible and plenty powerful 3UR-FE, the long-term king of all modern V8s.

          1. I own a 2015 yukon SLT (my 2nd yukon) & a 2016 LX570 (my wife’s car). My yukon is FAR more comfortable on road trips, tows more, and is my preferred vehicle to drive daily. The lexus gets absolutely awful gas mileage, AND has a tiny gas tank to boot. Wife likes the Lexus, and I like the Yukon. I have ordered the 2018 yukon denali, and can’t wait.

        2. The Denali is great for someone who doesn’t go off-road and wants lots of creature comforts. I’ve had two Sierra’s so equipped and have always gotten terrific discounts in them that offset the price premium. To the point that the one I currently lease would have cost more for a lesser equipped SLT at the time.

          I would definitely have gone with a different configuration were I oppkaningon spending any real amount of time off road though.

      3. If you want to go “anywhere,” you’re better off with a Jeep Rubicon. Get some good modifications. I just wish portal axles were a factory option. Maybe Ford will do that with the Bronco.

        1. With a Jeep Rubicon, you’re lucky to “go” to the end of the street before it breaks down, much less “anywhere”. Worst reliability known to man.

    6. It seems like the better question would be “Do I buy a Yukon, or simply wait for the 2018 Expedition / Navigator?”

    7. It seems the guy asking the question likes the GMC.It also seems like you guys don’t.

      To answer his question I would say yes,go for it.You like the GMC,buy what you like.

      If anything goes wrong,you’re covered under warranty,just like all the other oem’s.

      As for the rest,I’m about tired of the ford vs gm constant crap just like on putc.How about this,keep the brand vs brand crap to yourselves and stay on topic.

      1. Certainly some people go overboard with the brand thing. But you have to admit, brand talk is legitimate. There are general tendencies. Different companies produce different products. You can’t deny that Toyota and Lexus make better quality vehicles in general. IF you do deny that, I can’t help you. You are too far gone for now. But if you can accept reality, then we still need to encourage brand comparison. We just need to discourage unreasonable brand comparisons.

        1. It’s YOUR opinion that toyota or lexus is a better quality vehicle.I don’t care one way or another. I buy what I want,and whatever brand/model I want.

          Whether or not that makes sense to you means nothing to me,unless you buy me the vehicle.

          As for brand ‘comparison’,that is subjective as hell,fuelled by brand loyalty.

          “brand talk” is good,damn good.Brand bashing isn’t. Again,it just highlights the posters brand loyalty,which again is very subjective.

          That is the ‘reality’ that I accept.
          About toyota,I have never owned a toyota truck,and I never will.Why? Because they never made anything I wanted.I never liked the taco,or the tundra.

          I prefer chevy/ford/ram/and jeeps.And that’s th’ facts jack.

        2. Once upon a time I would have agreed with you but not anymore. The domestics (ar least GM and Ford) have caught up to Toyota in the quality department. Now they all have various models that may do a little better than the other guys but it’s give and take. I work on JUST AS MANY Toyotas as any other mahor manufacturer

          1. Agreed. My dad’s transmission shop works on an awful lot of Toyota’s. Keeps the money rolling in.

            1. Toyota trucks with Aisin transmissions? Or Carollas?

              The Aisin-equipped trucks are invincible in that regard.

            2. Mostly Tundras. The Aisin transmissions don’t hold up that well, whether it be in a Toyota, Ram or any of the others.

            3. I should state that most of these Tundras appeared to be used for work. Some had obviously done some heavy towing. Basically doing the work that would normally be reserved for a 3/4 ton. I can only guess that people assumed that because it was a Toyota that it could handle it. My impression is that Tundras hold up pretty well when they are used as designed-a 1/2 ton with light haluing/towing duty.

          2. “The domestics (ar least GM and Ford) have caught up to Toyota in the quality department.”

            That’s just not true.

            1. @RUNUOVR: Watch out, as it just might be true. I’m going to research the following “Are the Tacoma and Tundra the worst vehicles produced by Toyota in recent history?”

            2. Domestics are generally better than they use to be and the Japansese have gone down somewhat but I don’t beleive we are at a point where it can be said that they are the same, quailty-wise.

        3. Yet the 2016 Tacoma has been a quality disaster thus far. Engine problems, transmission problems, rear axle failures, least reliable midsize truck according to Consumer Reports, lawsuits over rust rotting frames, etc. Then there’s the oil burning issues with their 4 cylinder engines. My wife’s 2010 Corolla burned more oil than any vehicle I ever owned. Toyota’s older vehicles were rock solid. These days… eh, I’m not impressed. I’m certainly not paying the premium prices Toyota dealers want for their vehicles.

      2. Exactly Lohchief, people should buy what they like. I have a GMC, but I did look at the competition before leasing my current truck. The Fords were not nearly as good a deal at the time I got my truck, so I went with GM.

        Not to say I wouldn’t consider a Ford next time, or even maybe a Ram.

    8. My suggestion would be wait for the 10-speed. However, I would wait so I could do an assessment of the 10-speed and decide then whether or not to get the it or opt for the 8-speed on discount.

    9. I’d wait, the ’18s are probably a couple months out. Think gm usually has next model year starting September.

    10. If I wanted a GMC I would wait. The thing is the new ten speed will be out as the last 8 speeds are on the way out so drive them both and see what you like. Plus if you like the old one you could likely get a killer deal as they want to move the old ones out. I don’t expect much difference in economy between the 8 and 10 speed. If they keep the gearing in the rear the same. Maybe a slight improvement in acceleration.

      As far as the 10 goes, i would not worry about reliably issues. Both Ford and GM designed this together and they have historically built really sold rear drive transmissions. This I don’t think will be any different.

      1. There last few transmissions have not been that great-particularly the Fords. Again, they keep my dad busy at his transmission shop. Only tranmission that seems to stay away from the shop is the Allision. Ford and Dodge tranmsission keep him very busy, a good many of the older GM’s as well. More speeds are more complex and likely to lead to more problems-there are just more parts to fail. Like all new transmisisons there are going to be some teething problems.

        1. Honestly i have seen an absurd amount of transmissions get rebuilt due to drivability issues instead of actual transmission problems. Transmission shops are in the business to sell rebuilds, whether they need them or not. So I hope you dont mind I strongly disagree with that statement.

          1. Just stating the facts. These are broken transmissions (broken hard parts, burnt out solenoids, etc). All makes come through but as of recent there has been a greater number of fords-disproportion to their market share. Granted, that’s just one shop. Maybe it is an outlier.

        2. FYI, your dad cannot work on Allison transmissions. They are very particular on who even touches them. In many cases even dealers cannot overhaul them. Just swap the box.

          1. That is not true. You are right in that many shops do not touch them however. But there are a lot tranmisisons that some shops will rebuild while others go the remanufactured route.
            Even if the shop is not rebuilding the Allison they would be doing swaps with remanufactured units-even this is very rare. They just hold up well.

          2. BTW, I’m pretty sure that dealers never overhaul any transmission. They swap parts, that’s about it.

            1. Once again you are wrong. Dealers in general rebuilt transmissions. Allison is one of the few that limits dealers what they can and cannot fix. Aisin is also one of them.

        3. Well, if “your dad” works on a lot of Ford trannys, they must be junk!

          Ford makes some of the best transmissions in the business.

          1. I didn’t say they are junk but he does work on a disproportional number of them relative to the number of Ford trucks on the road. The Ram transmissions seem to do worse-if that makes you feel any better.
            Basically my point is, even the new transmissions are not as reliable as some would like to believe. There is a steady stream of broken transmissions coming in-even from the newer HD trucks. The one exception is the Allison. GM transmission seem to have fewer probelms than the other two but they still have their own problems. They generally are easier to fix however.

            1. So what is the ratio of trucks on the road vs what your daddy fixes? Your whole story smells of dog poo.

      1. You got one of the rare lemons Toyota has ever made. Bad luck. I’m sorry. The vast majority of Toyota owners quickly realize Toyota’s supremacy above all other automobiles and never leave the brand. I personally feel blessed to experience one of humanity’s all-time engineering achievements every time I drive my Tundra. Toyota quality is a living testament to the potential of the human species for greatness.

        1. @RUNUOVR: It’s wasn’t as rare as you claim. When the chief engineer was asked about the repair history for my former ’11 Tundra, his response was “Not ours or TSB”. If you like, I’ll site my source at THQ. Honestly, when I read the article, I thought his response would have been something like “Unfortunately, he ended up with a Tundra that had a convergence of out-of-spec parts”. Instead, the response deflected blame. Really?

          Also, the difference between my negative posts about Toyota’s Tundra and your “positive ones” is I post facts. I don’t make stuff up.

          “Toyota quality is a living testament to the potential of the human species for greatness.” I’ll tell you right now, you’ve never had to put “Toyota Care” to the test. I did and I was appalled at their incompetence–they couldn’t even take the time to read a detailed email.

          Another example of incompetence: the chief engineer claims the 4.7 liter million mile Tundra only had two time chain replacements. I’ll let you figure that one out.

        2. I think you’ve been run over by a giant tanker of Toyota Kool-Aid. The Tundra is a good truck, but it is old, ugly, slow, inefficient, and lacking a lot of the modern tech found in other trucks. America dominates the truck market, and its simply because they make the best trucks.

          1. I’ve been drinking the Toyota kool-aid for nearly 10 years now. Great stuff and keeps me out of repair shops.

          2. So does the million mile tundra guy. It was said he got his 16th owned tundra for free.

        3. “Rare lemons”? NoQDRTundra’s problems are not rare. Especially the rusting bed and tailgate, which is a quite common issue on the 2nd gen Tundras.

          Toyota quality ‘was’ a testament. That quality was slowly withered away over the last 15 years or so. Now 5.7’s that leak oil, front differentials that howl and vibrate, rear axles that leak and lock up, 3.5L V6’s that stall and leave owners stranded, frames that rot away after a few salty winters, etc etc. are normal problems Toyota owners deal with. Considering even Consumer Reports had to admit the 2016 Tacoma was the least reliable midsize truck, something is definitely wrong at Toyota.

    11. 7.5% improvemnet in fuel economy does not seem small to me! I doubt there will be that big a difference from an 8 to a 10 however.
      Likely the price difference between a clearance 2017 and a new 2018 will be significant. I doubt there will be much noticable difference between the 8 and the 10, in fuel economy or performance. A few thousand extra dollars in your pocket could easily makeup the differnece in lifetime fuel consumption.

    12. Neither! If you feel a need for that kind of vehicle your money will be better spent for a penis extension. Then maybe you’ll feel better about yourself.

    13. I’d say wait but if the GMC dealer starts discounting the heck out of a 17′ denali I’d say go for it. You’d still come out ahead even if there is a noticeable MPG improvement. aAlso remember, the F150 went from 6 to 10 speeds so yeah a difference will be seen. Going from 8 to 10 will not be as big at lest on the MPG front.

    14. I’d wait for the 10 speed to be released. Then you can see how it does. If you drop back to the 8, you’ll probably get a better deal. If you jump on the 8 now you’d always have the “what if” until you get to drive the 10. Based on what I’ve heard regarding the 10 speed, I think that will be an awesome transmission.

    15. I would wait on the 10-speed transmission. The discounts start early and heavy on these SUVs anyway so if you wait a couple of months the price difference will be negligible yet the hit on resale will be more bearable because the resale of the GMC Yukons are among the worst in the industry. I learned this the hard way. Also, the transmission was codeveloped with Ford so your chances of getting a good transmission are much better! 😂

    16. You Toyota fan boys crack me up. We have 3 tundras at work and they eat wheel bearings like crazy. The tundra is a good truck but I wouldn’t say it’s better than a ford or gm.

      To the Yukon Denali delema I’d wait and try the new expedition out as well unless you have to have a v8.

    17. I think he should drive the new Ford as well, it finally looks good. They might even offer the 400HP 3.5 upgrade and it will have the 10 speed with superior torque over anything GM offers unless you cannot do without the V8 accoustics. Also the underlying theme I am seeing is that GM has vibration issues that they cannot fix. Why would anyone pay good money for a new vehicle that is likely going to be plagued with a vibration issue or did they fix this?

        1. Lohchief you are reducing my options significantly for the fall. I was looking hard at the F150. Maybe I will buy a Ram. If you can feel a vibration and all the manufacturer has to do is say it is within limitation then what is this world coming to, where is the warranty in this, I feel sorry for these owners. This is why people rant and rave over manufacturers Lohchief, once you have been screwed like this you never want to return. Just hearing that has turned me away from GM and Ford. A vibration that is within spec, JFC. I have never been so scared to buy a new truck. We should be scared of used not new

          1. I know exactly what you’re feeling. I won’t go into the details,but once upon a time I was a hardcore Ford man.

            In 77 I bought a brand new Ford Granada,loaded.Great for the family,I thought.

            It was a nightmare from almost the beginning,including a rear window that leaked whenever it rained.

            Under full brand new factory warranty,I couldn’t get ANY dealer to fix it.

            That was THE deciding factor to NOT BE BRAND LOYAL ever again.

            And that opened up all the other possibilities that I would have overlooked,because they weren’t a Ford.

            Life is way too short to go through it with blinders on,so I took them off,and never looked back.

            Btw,I bought new f150’s in 02,and 05.The 02,(ext cab,6ft bed,fx4,5.4) was an awesome truck.

            The new 05 with the 3 valve 5.4 on the other hand sucked.

            I keep my options open to brands/makes I like,and ignore the rest.

    18. If you think the 10 Spd is worth waiting for I’d say wait for them to be out at least a year before purchasing. GM is famous for using the buyer as the final testing phase on their vehicles. Just think about their first diesel vehicles… The almost singlehandedly put a bad taste in peoples mouths regarding diesel engines in general! I used to own an Olds Cutless (we called it the gutless cutless) that GM had replaced the Diesel 350 with a 307 cu in engine (at least that is what it said on the air cleaner) the original owner said it had been as reliable as an anvil after the engine swap, and it was more powerful than the oil burner. He thought that GM did him a favor by replacing the engine until it came time for a trade-in and then none of the dealers wanted his trade. I purchased it from him for $3500 less than what people were asking for a cutless with an original V8 engine and he was excited that I was even interested in it. It had some strange vibrational resonances at 50, 65, and 75 MPH that nobody could figure out. One mechanic suggested that I not drive at any of those speeds and so that is what I did and the problem was solved. I sold it for what I paid for it and bought a Camry that I proceeded to put 240,000 miles on and in that time, the ONLY things it needed was a starter motor and a heater/ac fan motor, while in my posession.

    19. Tote:
      One of my brother in laws bought a new chevy pickup back in the late 70’s or early 80’s that had that diesel.

      If I remember correctly it was naturally aspirated,and a gutless wonder,and a maint hog.

      At that time he was a career navy cb,so the maint was always spot on,but he knew he was just polishing a turd.

      Live and learn…

    20. Every manufacturer at some times makes a few bad vehicles. Some more than others. GM has major issues that they cannot fix but I hope the next generation of trucks fixes the vibration issues. Ford and all other manufacturers have also had their share of vibration issues but it is minuscule in comparison to what GM has going on. Your chances at getting a good Ford are much higher. I hope to see GM back in the game soon. I say buy what you want but if GM is what you want wait on the next gen.

    21. Personally, I would avoid something as complex as a 10 speed transmission the first year GM is offering it. Early adoption of new technology is fine provided you are in a financial position to deal with the potential consequences of such a purchase. If you are an early adopter of a smart phone, fine. If it goes bad, the price for getting out of it and into a new phone will not break you. When you are talking about a big ticket item like a truck, the cost of getting out of it if it’s bad could hurt you.

      I just picked up the all new 2017 Honda Ridgeline and I love it. However, with that particular vehicle there wasn’t much risk because although all the technology was new to the Ridgeline, it was not new to Honda as they had used all of this stuff in the Pilot with no trouble. Interesting point though, In the top trim level of the Pilot, Honda offered an optional 9 speed transmission ( all new ). I spoke to the service manager at Honda and he told me the ONLY real problem they have encountered with the Pilot were problems with the 9 speed transmission. With the Ridgeline, Honda wisely side stepped this issue by not offering it. Only the 6 speed is available and it is tried and true. Bottom line? If you can afford the potential consequences, go with the 10 speed. If not, tried and true beats all new most of the time in my opinion.

    22. Buy whatever Denali you like and dont look back and enjoy it. Drive it, maintain it, and don’t worry about anything else. Life is too short worrying about the small things.

    23. So what is wrong with the 8spd Automatic? Maybe that is question everybody should ask?

      Another reason I’m holding back buying a SD Ford is possible a 10 SPD Automatic.

    24. The chevy shake will keep you up at night.
      eventually your knees will knock all the time. whether in the truck or not sort of like having a bad case of shell shock

      1. David, WTF are you talking about? I have a ’16 Sierra 1500 with the 6.2 and experience none of that.

    25. Three weeks ago I purchased the GMC Yukon Denali 2018. I have already had it in the shop for a shutter in the transmission. We have felt it at different speeds. I wasn’t aware at the time when i bought it that it had the new 10 speed. It is so new that even the Dealership had to contact GM Directly for help. Needless to say they said it has a new Feature that the Vehicle Learns your “Driving Habits” and adapts to that.This issue should correct itself. Lol. Not sure how much I believe that. We will see in the coming weeks if this problem persist. Either way, it’s under warranty. Other than this issue, the Denali is an awesome vehicle with all the Bells and Whistles.
