I have always used a basic stack plate style cooler mounted in front of the radiators. Usually something around 12" x10" or there about. The size depends on what I'm working on and the room I have where I want to mount it I typically make brackets and mount it behind the grill somewhere, not up against the radiator.

I've never had any adverse affects on engine cooling on any car.

I run them all the same way, through the engine radiator first and then through a trans cooler, back to the trans.

2 of the cars have 4l80's so I can easily monitor trans temps. From what I've seen they run about 20 degrees cooler than the engine does.
