As Im getting ready to do some HPDE this fall Im wondering how my trans will hold up against the heat, especially with a Yank SS 3600 torque converter in it. I already have a decent cooler, 11x10in plate style, that keeps my trans pretty cool even during some major canyon carving and 2nd gear pulls. Trans is race built as well. Just wondering if anyone is running multiple coolers and also if affects cooling? I still have a stock radiator and I wonder if two coolers in front will block too much fresh air from coming in or will it just pass through them? Any advice is apreciated,thnx.
