i only really posted the jb weld as a joke..but it actually works...could be a temp fix until you figure out what you actually want to do fix/swap wtvr...
My old mk4 gti vr6 had a crack in the tranny, previous owner had it welded....garbage! Leaked everywhere! My clutch/flywheel/pressure plate were drowned in tranny oil. My solution: bought a used tranny and sold the car.
I know how you feel and seeing you have a auto tranny sucks even more cause they are so hard to find. Good luck!
