[gforceman]

since my 03 explorer has a towing pkg is there a separate cooling radiator for the tranny or does it use the engine radiator itself , also on the transmission which line is the RETURN LINE from the radiator back to tranny the top or bottom line

Bottom line is the return, the line on older models comes out of the radiator and goes to a trans cooler and then back to the trans.

There is a separate transmission cooler. It is located in between the radiator and the A/C condensor. If you remove the plastic piece on top of the radiator you can look in the space between the radiator and condensor and the trans cooler is located at the bottom of that space.
