So I took the 4t65e-hd tranny to the car wash and pressure washed it, but the axle holes and hole for the torque converter weren't plugged, so water may have gotten inside. Not sure if this ruined the tranny or not? No one told me that water could ruin it until after. I'm really scared that I may have ruined a perfectly good tranny! Not sure what to do...
Well, you don't want water in there because you certainly don't want rust.
In my opinion, I would try to drain it as best as I could, and then stick a hair-dryer into one of the axle holes. Eventually it will dry out. Then I'd spray the hell out of the inside (every hole) with WD-40. WD-40 obviously isn't the most ideal thing to use, but it'll coat it and prevent it from getting moisture.
You've not ruined anything, so don't worry about it.
But when you do install it, you'll want to change the fluid after a few runs. Kind of a waste of transmission fluid... but you just don't want any crap in there.
