I'd recomend everyone do this, especially if you question where full is on your tranny stick...
I had an issue with mine a while back where it began puking fluid after a fluid change.
Pull the pan. Leave the stick in. Put the gasket on and lay a straight edge across the pan surface. That's fulll. Check it against the full line on your stick. Mine was seriously overfilling the transmission, thus why it was puking fluid.
