I was wondering what the proper operating temp of Tranny fluid would be, someone mentioned that "foaming Fluid" does not disappate the heat very well. How much temp difference does having the TC Locked and Unlocked have?
How important is having an external tranny cooler? How much difference in temp should that make? Would boiling tranny fluid bust seals? How much PSI should the Tranny Fluid be under when vehicle at Idle and Running, what range are we looking at here? How do you determine the size of the Tranny Cooler required, is there a formula?

Any info is appreciated thanks.
