Well, I finally drained everything completely & blew 20#'s of air through the dipstick & filled it back up tonight, but I think it's still leaking!
I put a piece of cardboard under it after I test drove it & there was a small puddle of fluid on it after about 10 minutes. Could some kind of seal have gone up there? I'll look at it closer in the morning to see for sure where it's coming from, hopefully. I'm starting to think it's about time to do my 4 spd manual swap soon!
