Trans dipstick
I have a '02 Ford F250 with the 7.3 diesel. I put in the 6.0 trans cooler, my dipstick should show over full because it takes an extra quart of fluid. Is this correct ?

I don't think so. If you need to add extra fluid to fill a larger cooler, that fluid should stay in the cooler and thus your trans level should still read full at the old mark, it will just take more fluid to fill the entire system. Overfilling a transmission can lead to blown seals and "frothing" of the fluid that could come up through the filler tube and leak on the hot engine.
