I have the OEM tranny cooler on my truck. Has anyone found a benifit in upgrading these to a larger size?

 

i think it will help in the long run. i think one of the bigger ones willl always help since these trannies are so sensitive. cheap and good upgrade for longevity.

 

On my LS1 camaro, I put a hayden from pep boys in prior to the converter, then I beat the living hell out of the tranny and it never broke. Heat kills auto trannies, and I even used to spray the thing out of the hole and it was a stock tranny with 75,000 miles on it. So my answer would be do it, I am going to.
