No external cooler, only connected to the radiator.
A crack in the rad cooler sucks, this is a brand new radiator.
If I add an outside cooler, and eliminate the rad cooler, will changing the fluid in the trans pan and blowing out the cooler lines be enough to remove the water in the trans?
No. The entire fluid is completely contaminated. Don't forget you gotta get it all removed out of the converter, and all of the internal guts of the transmission,too.
