Ok, I took a picture of my paperwork. It has a tsb and SLF code# (whatever that is) hope it can help some of you like it has me. Truck is still shifting great so far.

 

I did read in another unrelated post that some one else had gotten an 8 speed update and truck is also much better and his has been in for a couple of months. So it all sounds promising.

Let us know how it works, That TSB came out in Jan

Mine had it applied Jan/Feb timeframe.

 

Trans is much better. haven't had the severe harsh shift after sitting since, and in use shifts are much much better as well. Still sometimes as a small clunk when coming to a stop -- like 2-1 or 3-1 shift.

 

Autotrac transfer case recall applied this week.

Guessing because it was a recall you got a letter? So hopefully if we didnt get a letter then the transfer case wont apply to us.

I had mine in for an oil change last month and now that you mention it, it is shifting better. They told me they did a trans update but I didn't think much of it. I was too focused on their asinine excuse for my harsh shift from Park to Reverse that was happening randomly say every 10th time I made that shift. They said it was because my AMP power steps were plugged into the USB and they were drawing power and taking it away from the TCM module. I just laughed and left.

Had mine in for oil change a few weeks ago and for the hell of it I told them about the hard downshift into 1st and they did the same thing......now almost perfect. Every once in a while it'll do it but not as bad and not nearly as often.

Didn't get a letter. Service called it a recall, but paperwork just refers to transfer case control module (TCCM) reprogramming to eliminate 4HI lockup. (truck has never had any problem with the 4wd system - and in fairness the 4wd doesn't get used often).
Dealer found it when checking VIN while it was in for the last 'include' oil change.
Also added a new retainer bracket to drivers seat to stop the lateral movement/click of the drivers seat when doing low speed turns. (guess I should probably should find the thread on that subject and add the info there )

Hows everyones trans doing? Mine is still doing great after a few weeks, its pretty dang smooth I love it.

 

I am going back to my dealer soon I thinkn Im getting a vibration after a tire rotation and think a tire may be out of balance. I will confirm with the service guy that they did the update. They also have a new 4wd controller on order to get rid of that high pitch frequency :-)

Mine is doing great so far.

Thanks for posting this, OP. My new wheels and tires get here tomorrow, and after putting them on I'm going to be making a dealer appt to get this done to my trans, the speedo calibrated, and my shifty seat fixed.

I just had mine done today. It is obviously in learning mode still but it isn't that smooth yet...

When you brought it in for the update, did they provide any insight in terms of how it will improve the shifting, etc. Is the "learning mode" the same as it would be when you first start to drive a new vehicle?

The new programming has a new set of shift parameters according to them. The relearning is how the trans adapts to your driving style...hard accelerator or not etc.

 

Time will tell. I only drove it 25 miles home.

      Transmission Temperature Hitting 220s

      By newdude · Posted

      It is working as designed.  NHT and non NHT trucks have the same exact transmission cooling setup.  NHT just gets a larger radiator.     The transmission cooler loop on these is as follows.     -Transmission out goes into an oil to water heat exchanger (item #1 in the first illustration below).  This exchanger has engine coolant opposite the transmission fluid and uses engine coolant to warm and then regulate the transmission fluid temperature when its in the operating window.   - From the cooler it goes to a thermal bypass valve (item #11 in the 2nd illustration below).  If the ATF has not reached the temp to open the bypass (194F), it loops back.   - When it reaches 194F, the thermostat opens and ATF then flows out to the oil to air auxiliary cooler (item #17 in the 2nd illustration) at the front of the truck.  From there it goes back to the transmission.     Your only fix would be to swap for the PPE thermal bypass delete block which will open the loop to the aux cooler all the time.  It will STILL run warm, probably 170-200F, but that's as low as you'll get it as its still flowing through the oil to water exchanger.

      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!
