So this started a while ago, probably around 250k miles. I thought it had to do with the rearend going out because it seemed to go away when I replaced it. But it didn't. As far as I know it is the stock tranny but I am the 3rd owner and have had it since 200k miles. Any thoughts? I'm at a loss. And just so you I have been lurking and searching all over the place on this subject and nothing has matched up.

First - Does it have the proper amount of fluid?

Second - When is the last time that it was serviced?

Third - You got 250k out of it and I would consider that pretty darn good.

It needs to be serviced the last time was at the dealership that I bought it from, so almost 90k miles ago. fluid is over full when hot, I've been meaning to pull the pan, change the fluid and tig in a drain plug. And I am not complaining, I just dropped the cash on a new rearend and want to rebound a little before throwing another chunk-o-change at it.

 

Thanks-Erik-

      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!
