I need to know how to tell if my radiator has a tranny cooler on it. I looked, and have no clue. I also need to know if how to tell is the same way as an s10's radiator.

 

Look on the passenger side of the radiator, there should be 2 hard lines (one at the top, and one at the bottom)

 

The s10 will have the same radiator, so long as it has the same options. If im not mistaken, all the second gen 4.3 auto s-series have tranny coolers. The pressure line will be the top line into the passengers side of the radiator, and the return will be the bottom line.

 

stick shifts dont have tranny warmers. i think that all of them have an oil cooler, and most, if not all, of the automatics have a tranny warmer.
