Transmission Temperature

[HummerMann]

I've noticed that driving in the 98F temperatures we've been having my transmission has been running at about 190. How does your transmission temperature run in hot weather?

In 100 degree temps mine runs around 175-190 range.....when it's that warm out it's gonna run about same temp as engine temp, which is usually around 200....if it gets higher I'd be concerned

It was 103 in Vegas today. My transmission temp was about 190 also.

I installed the larger cooler mentioned on this site right after I purchased my 05.
In AZ with temps at 112 my tranny temp barely reads 150.

The cooler seems to work great. I've had it on for about 8000 miles so far

So I've asked this question a few times. I was in the mountains in February, and it was -20F and the tranny, while pulling a trailer with 4 mountain snowmobiles on it (500# each - probably 1.5 tons total weight with trailer) and I was running trans temps as hot as 225-230F. Much too hot in my opinion, but when I talked to the dealer, they *claim* that this is normal and that it could go as high as 250F.

In my racing experience, anything under 200F is good, anything over 210F is bad, so it concerns me when it hits 225F and I can *smell* it!

What cooler did you buy, where did you put it, and how did you route the lines? Did you have a factory cooler as well?

Most everyone installs the Tru-Cool Tranny Cooler. I did it and like mentioned run 150ish. Last week I pulled an empty 24 ft Haulmark Trailer about 3500 LBS and ran about 190.
There is tons of info on this forum about it.
IMO this is 1 of the best MODs for the money you can do.

Yep, Tha'ts what I used and used the write up on here for the install.
I just completed my second 3200 mile road trip with it from AZ to Illinois
works great at 116 degree outside temps running 80 up some big ass Hills through northern AZ

I am very interested in doing this myself. Could someone list all of the part # needed to do a very proffesional job. I would like all fittings to fitting where possible. Has anybody done a write up yet? If not I think I will do one, with photos.
