Right or wrong, I ran only the B&M stacked plate cooler without the radiator loop. 904 Manual V/B behind a 340 all around Clearwater & Tampa stop & go for years with zero problems.
I can believe that I only ever ran a cooler. But I believe foot braking the car with a 5500 stall was getting something hot.The trans never flared like that until we would go rounds in a row.
