Whats the easiest way to tell if I have a transmission cooler.
I have a 2000 F-150.

 

Stand in front of your truck and look downward through the grill. The PS cooler is on the right (driver's) side and the AT cooler is on the left (passenger's) side. If you want a closer look, open your hood and look where the AT lines route into the driver's side tank of your radiator. One will exit and route down low, over to the AT cooler.
