Did some research on tranny coolers and ZZP does not recommend them at all. They quote them rather dangerous than safe. They say that the 4T65e trannys don't have a problem with heat and a lot of people don't realize that. My question is, is it a mod worth the money.? I mean my stupid tranny only slips/shifts hard in the heat so that would make me think that its getting too hot! Has anyone ever installed one? What were the results if so? And why is ZZP saying the 4t65e trannys don't have a heating issue but*people*with this tranny are having the same symptoms in the heat?
