the pcv plate and all of the intake gaskets should take care of it, don't forget the gasket on the front behind the throttle body as they crack on the bottom. disconnect the computer for a minute or so to let it reset so you get a fresh start, i pull the intake with all of the wiring and fuel system atached. it's possible that the tranny cooler is leaking into the coolent, that's not usually a good thing for the tranny to get water in it, i am not sure about that unit but i know the glue that holds the friction material to the discs on a older 4hp22 is water soluable, some trannys can handle it and some can't, if nothing else it's a bitch to get the nasty pink goo out of a tranny that has gotten wet
all america wants is cold beer warm cat and a place to take a poop with a door on it
