Do you have a factory trans cooler? If so, you can just run the factory cooler to the Hayden, then back to the tranny. That is how mine is setup. There is not a trans cooler too big...the cooler it is...the longer it will last.

yea what is he talking about too big. if it is a little big then just add like half a qaurt of transmission fluid but i dont think you will have to.
