I've Got a few Radiator/Trany Cooler Questions

That fan and radiator combo should do the trick. Just make sure it's going to fit. I tried an electric fan on a stock type radiator(3 core) and there just wasn't enough room between it and the water pump. On the tranny cooler the bigger the better. About the AN fittings the tranny itself has 1/8" pipe threads where they screw in. If you cut the steel lines get some 5/16" to #6 hard tube adapters to AN from Summitt or Jegs. I believe the radiator fittings are 1/8" pipe thread also. They are on mine.
