Ok... I just got a new to me, used tranny. I just changed the gasket and filter on it before I ran it the first time. Drove it round town for a bit and it shifted great. Decided to run to store (bout 20 min away) and it dumped all the fluid out. I drove it slow in second about 5 miles so I could leave it somewhere safe. By the time I got it pulled over it wouldnt move at all. Going to change gasket and possibly pan if its bent and not sealing, in the am. Whats the chances its not hurt and will run again?

Also I know its leaking from pan. Already looked.
