I added a 26K towing tranny cooler to my truck, and so far the tranny has not exceeded 190 deg. The big test will come this weekend when I'll be towing my 34' travel trailer over the Allegheny Mountains in 95 deg heat. I installed the after market cooler in the same fashion as the dinky stock cooler: fluid runs from the front of the tranny to ther radiator, then to the cooler, then to the back of the transmission. I read an article that suggested bypassing the radiator altogether. Makes some sense to me, but is there a good reason to continue to have transmission fluid flow through the radiator? Appreciate the help!
