Thread: Transmission temperature
02-24-2014, 12:43 AM #1
Hey everyone, I'm new to this whole thing and I just need some help on figuring out the normal trans temp on my 2008 silverado 1500. I've noticed lately that it'll warm up to about 200°F, is that normal? What happens if it gets even hotter? I bought it used about 8 months ago so I want to make sure my unicorn is always satisfied!Using Tapatalk

Right now (winter), it depends where you live. I take it you are in a warm climate. Here, it has been a cold winter, mine hasn't gotten above 125-150 all winter

My '08 with 33's, 3k stall and tru kool 40k sits about 80° above ambient. If you are seeing 200° without ragging on the truck something is wrong.

Like said above the fluid and filter change might help, but deffently would not hurt. If you are running larger tires and you happen to have the factory 3.08 gear that might increase the temp as well.

this is a good tool [temp tranny ] to alert the operator that the transmission is in need of some work... hopefully you will just need some new dexronVI and a filter...
engine temp should not be 200 or more deg f.
I hope your where it is above 80 deg f air temp....because if it is 10 degf and you have 200 deg f tranny temp you could be in an expensive fix.
