Th 350 Leaking from tailshaft vent???
Hi everyone, here's my problem. I have a th350 behind a sb 350 in a vega. The trans has the short tailshaft. It always pukes out the tailshaft vent for some reason. I had it on stands running in gear and sure enough it coming out. I removed the tail housing and everything looks ok. It keeps leaking out until its to low to run and starts slipping. I rebuilt this tranny myself. It was my first th350 but not my first rebuild. Did I miss something? I dont have a clue why its leaking out of the vent. Any help would be greatly appreciated. Thanks in advance for any help.
