Do i need tranny cooler?
then you got lucky. ALWAYS, ALWAYS, ALWAYS, ALWAYS run an after market cooler, even on a stock auto trans.
when you have an after market cooler the only thing the stock cooler will do is decrease flow through the AF cooler and heat up the fluid, if a car is running temps higher than 175*.
