I agree what Peter said, Ive been driving a pro car as a daily driver for the last 24 years, and I have never had any problems with the way GM did it (without the cooler). The one I posted is the first car Ive owned with one, and that is because the car was originally a 3 speed, and now has an automatic, so it has to have a cooler, since the radiator has no built in trans cooler.
