From what I've been told from some pretty reputable guys around the message boards, you never wanna run your tranny temps over 200 degrees for any length of time. Those temps put a beating on your fluid. With my 6.0 cooler, the lowest I run is about 140 degrees, and the hottest is about 180. Usually stay about 80 degrees above ambient.
This is pure bs. I know because ive DONE way worse. Ive got the trans up to 280° before. Got the truck stuck in mud with 38" tires and a loaded trailer. When I got it unstuck, it was 280 at least. The fluid was burnt, no arguments there. But I changed it that night and that trans lived another 140k miles. Overheated many times after that. Once I put synthetic fluid in, it never burned the fluid anymore but would still get hot. Sometimes you arent moving enough for coolers to matter.
My experience was corroborated by mark kovalsky and he said the temp thresholds are higher than internet folklore has propagated.
Is it good to burn fluid? No is 220degrees bad? Not at all. Is 250? Yea, for long periods.
I like the guys with stock trucks who run auxiliary coolers and brag about how it only hits 140 in the hottest summer conditions. Good way to rot a trans out 75% of the year with cold, wet fluid.

Jomax when did you get a 15? I still thought you were just looking...
Nice! that'll keep ya distracted...haha
I already have the VB and literally shifts the same as my brothers BTS, tires are aready junk from the crazy shifts! I baught track bars today. I will look into acquiring a 4r100. I already have a trans gauge, just waiting for winter to pass so I can some different wiring ( I cant pull it in the garage, too much supplies inside for building my house in NH), I digress, the cooler was a gift, my trans really only gets hot in the summer time, I was putting it in because it was free and for support. and BAMFO, how much for the wicked wheel 2? will it fit my turbo?
