on the th350 which hole is which(for the tranny lines)? which one is for the incoming fluid and which is for the outgoing fluid? Sounds kinda funny but i don't know how else to word it.

 

I can tell ya one real messy way to find out. Crawl under it and get your face out of the way, and have someone start the car and shut it off after about 3 seconds. Whichever hole spews tranny fluid, is the outgoing port.


FWIW, it doesn't really matter if you're hooking up a tranny cooler. They work both ways.
