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.

      Most say the oil temperature needs to above the boiling point of water to rid it of moisture and long enough to dry it. Many think that is about a hour at 212 F or more. Those people have never line dried cloths in a Midwest winter. Leave a pan of water sitting on the counter and eventually it all evaporates. So heat drives the time it takes. Water in oil under 175 F, the Nitration initiation temperature, is a minimum then for temperature and samples I've done that use Karl Fisher method say about a hour (in a healthy well tuned motor) over 175 F will dry it to under 800 ppm. Low enough to not be much of a factor. Motors with weak rings will take longer and the colder the air temperature the longer it takes.   On a cold motor there is also the condensation temperature. Blowby gases that contain moisture are subject to that cold cylinder wall, like sweat on a glass of ice tea. But also subject to the Law of Partial Pressures. Wear studies by GM and the DOD  indicate wear is a real issue below 85 F and a concern to 140 F but doesn't become a minimal factor until about 160 F. You know this intuitively when you see water vapor exit the exhaust pipe until the system gets above the dew point. It isn't magic, it's physics and it fascinates me. I know you didn't ask but....I over share sometimes. 😉    You keep the Camaro's high and tight.

      Move further away.   Benefit of living out - none of our cars get short cycled, plenty of warm up time.   Curious how much time/temperature it takes to drive moisture/condensation out of the engine?

      Transmission Temperature Hitting 220s

      Switch a a 100% synthetic trans fluid, Amsoil works for me.

      Transmission Temperature Hitting 220s

      By DustMcGrath · Posted

      First of all sorry, I know there are a ton of transmission temperature threads...   My truck is a 2025 LZ0 High (10l89 10-speed) High Country with NHT max trailering package. The NHT package is supposed to have "enhanced cooling."   Normally the trans temp sits around 200. It seems like with any real stress it quickly jumps into the 220s (for example climbing a grade unloaded at lower speeds). I haven't towed much with this truck, but I'm concerned if it gets this hot unloaded.    I've tried a few different things to keep the temps down (tow/haul mode, sport mode, low range when that makes sense) and nothing seems to affect it.    I'm curious if others are the same behavior or if anyone has found techniques to keep the temps down. It seems like it just can't handle reduced airflow at lower speeds, even with relatively light loading.    Thanks!

      I'm at 105,000 miles on my baby Duramax. No issues yet. I hit 31 mpg's traveling through hilly terrain to a project in Colorado. I will buy another 3.0. I'm not concerned.
