I called today to see if my truck met the recall, and it did. Build date of January 2015. Taking it on Wednesday to have it taken care of, will let everyone know how mine drives after.

I had the update done and transmission learning resent on 11/3 and it seemed to shift better at the beginning, but seems to be reverting back to previous behavior. The flaring/clunk around 2nd/3rd also seems to be worse. The issue the dealer said didn't exist and couldn't replicate in their 5-10 minute drive. The tech just talked about the electronic transmission and passed it off as normal. I'll be going back to the dealership because this is not normal. I had a friend in the truck the other day and they totally heard and felt it. BTW I've probably put at least 250 miles on the truck since the update.

Well I just had mine updated today and picked up. Still early but after 40 miles of driving it definitely seems to shift better and no clunking. We'll see how it does after driving a while.

I had the update done a couple weeks ago and it seems that my truck clunks now more than ever. Drive-ability still sucks.

I had my truck inspected today, and they did the transfer case update. Right out of the dealership, I noticed it shifted different. A good different. My truck has 31,000 on it, and I am very "used" to the way it drives. It is definitely different.

 

About mid week, when I've put around 250 more miles on 'er, I'll post again.

 

 

No change in the way it shifts after update. Absolutely smoother upshifting. Especially going from 3rd to 4th in steady moderate acceleration. It used to hold onto 3rd (IMO) way too long. I've never had issues downshifting, and that has stayed the same. :thumbs:

I don't want to hijack this thread but last night on the way home my truck downshifted so violently it felt like someone had run up the back of me. I've experienced this 3 or 4 times now since I bought the truck. This is beyond the standard clunking/flaring I experience. My question is, since it's not happening all the time, how do I go about proving this to the dealership as I'm presuming this is not a good thing? And to be honest, when it happens it scares the crap out of me since you're not expecting it. As mentioned above, the dealership said there was no issue last week when I had it in. I'm not very experienced when it comes to car/truck issues and how to handle dealerships, so any input is appreciated.

Does it happen at the same speed every time? Can you tell if it's downshifting straight into first gear? That is indeed a dangerous situation.

I feel for you as far as the dealer. Bad enough dealing with them when you have a confirmed issue, let alone something that is hit and miss.

Did they in fact check the parameters in your trucks computer?

Done on 11/13/15 and it was wonderful until I drove it more and more. Now its not totally back to how it was but I still have that dreaded delay sometimes when accelerating.

It does happen around the same speed. Generally coasting and then I reapply the accelerator. It's definitely changing down to a lower gear, I'd say first or second. This time I was in peak hour traffic so not able to travel fast, I'd say I was down to around 20 mph when I reapplied the accelerator.

 

BTW, thanks for the feedback.

 

Edit: Ok just saw a thread below discussing this issue. Some say it's normal, some say it's not. I'll bring it up with the dealership.

      Trim level custom/pro

      Are you going to take long trips in it?  If so, try out the seats in the various trims. For me the lower trim level seats were not comfortable.

      I have a 2016 that I bought new and still own. I'm around 129,000 miles now. The biggest problem was a transmission failure about 2 years ago around 95000 miles. No warning, just failed while driving down a back road. A reman GM transmission installed and it's been fine ever since. A few other minor problems along the way. I am in no hurry to replace it. It's been paid off long ago and do plan on driving this as long as I can.   I will admit I am leery about all the additional electronics in the newer models and feel that it is just more potential problems. I think there's actually more than I would have wanted in this 2016 but so far so good. I think even if something major like lifter failure happened, it would still be cheaper to at worst, drop a new engine in than buy a new vehicle.

      OCI, not when but why?

      I’ve own several successful businesses. I’ve bought homes and lived in different states. I’d witness several generations buy homes and survive in different economic circumstances. You get awful sippy when people have different experiences than you do. You live a life. I’ve lived a life. It seems our experience has been different. You can point out generalized statistics. Some people learn how to thrive when the odds are against them. Living in different states does make a difference in a persons quality of life and economic outcomes and opportunities. That’s a fact Jack. It’s my truth, my life. Hard work and long hours the right environment made my families life easier. And yes moving to a different state increased the odds of that happening. Stats are generalized. People who thrive don’t make excuses. They beat the odds. Others get mad and point to those statistics. I guess that’s you. My post pointed out how you helped people beat the odds. Somehow your panties got in a wad. Go figure.

      Good question, I don't remember for sure but I believe it was the HD. I will check and get back to you.

      Point of the post sir was that while both wages and cost are rising EVERYWHERE; the cost is rising faster EVERYWHERE than the ability to buy EVERYWHERE. We're not going down the location rabbit hole. I'm aware of what economic migration is. I've lived in four states including Texas.   It's what "Purchasing Power" means.   I'm not telling you what I think. I'm telling what the government, your government, data shows.   It wasn't an argument. It wasn't a suggestion. It was a statement of FACT. You are absolutely entitled to your own opinion. Your not entitled to your own facts. If you and I were, they wouldn't be facts.    fact /făkt/   noun Knowledge or information based on real occurrences. "an account based on fact; a blur of fact and fancy." Something demonstrated to exist or known to have existed. "Genetic engineering is now a fact. That Chaucer was a real person is an undisputed fact." A real occurrence; an event. "had to prove the facts of the case."
