Autobox oil leak

[alanhack2]

Im wrestling at the moment with an oil leak from the BW35 gearbox on my V8 250. After curing leaks from the inhibit switch shaft and from the gear selector shaft, Im left with a leaky sump joint, having replaced the gasket twice and tried various types of sealant, the leak persists. Tightening the sump bolts (but not over tightening 4-5 ft lbs) seems to sqeeze the cork gasket out and makes the leak worse. Any ideas would be appreciated. Alan

Hi Alan
I had the same on my 1964 2.5 V8 - I could not for the life of me stop the "bolts" leaking.
I assumed it was a distorted surface where the gasget did not seat properly.
Eventually after 2 gaskets and various torque settings I settled on red hermetite on the gasket and around each bolt .
This has resulted in a minimal weep from a couple of bolts that takes days to drop onto the garage floor - so effectively I consider the leak cured !!!

Thanks for your reply. I think I have cracked it, I made a new sump gasket fom Rubber/Cork material which I got from Holdens and a smear of Wellseal, so far so good. I also found a leak from the kickdown cable which had no washer and was loose. To date I have a dry garage floor which is a first for me!
