18,000 GVW! I don't think I _need_ a better trans cooler. But..
My only concern is that I want the auto trans to last as long as possible. It has 83,000 miles on it now. Heat is a major trans killer. I rarely tow, but even with normal (eg "non towing") driving, would the auto trans last longer with a tube n fin? Would the factory stacked plate cooler be more than adequate, or should I look into a more capable aftermarket cooler?
It would probably be overkill in my case? Also the close proximity of the exhaust pipe/cat area to the transmission concerns me. I guess they engineered it right.
