My big diesel pickup typically only runs around 170F, why the heck do these things run so hot!

I hit 220* after about 60 minutes of driving in the summer. I stay out of the city as she gets to hot to fast. IMO, the factory tranny cooler on these cars is garbage. Ad an aftermarket cooler and you should see temps of 170-180. I need to get off my ass and install the one I have sitting at home.

Here's some info that I have been compiling over the past while..... http://chrisb.users.superford.org/Gr...on_Cooler.html

B&M 70264 is what I went with.

I added one last year to my 05' GTP and the temps went from the 220-230 range down to about 170-190 by the time I get home. The transmission coolers in these radiators do suck. I also had an undersized radiator as well it was 5/8" thick, just installed a 7/8" radiator (was supposed to be 1") and the temps seem to have evened out. The trans cooler is stand alone so I didn't expect it to change. I did have an issue Wednesday. I noticed I needed to go ahead and replace the lines since they were a year old and that's something I always recommend on regular trans hose and clamps. Well going down the street I was on it pretty hard and about the time it was at the top of 2nd all I see is a huge cloud behind me. I coasted the rest of the way to the house and could feel it slipping a little and had trans fluid dropping from all under the bodywork. The back of the car was covered as I discovered when I tried to lift the trunk and my hand slipped into the spoiler. So I cut the line and put new clamps on it until this weekend when I change the hose and look for something better. I lost 7 quarts in that time. So check and change those trans cooler lines even if you are using something better.
