Guys I have a th350 and was wondering which line coming out of the trans is the pressure side and which is the return line?I'm installing a trans cooler in my plow truck and would like to incorperate both the aftermarket cooler and the radiator cooler.I believe it would be best to run through the rad.cooler then the aftermarket cooler then back to the trans or do any of you run them aftermarket cooler then rad.then back to the trans?My thinking on this is to cool the best way.Thanks...John
