BW ST-10 UPDATE
 

Posted this awhile back but thought I would bring it up to date.
I have a ST-10 that would leak out the bearing retainer. I have pulled the trans and replaced the seal in the retainer and a new gasket. I have not put the trans back in the car yet. I was told that the factors that cause leakes in these were:

Bad seal
Bad gasket
Vent stopped up
Synthetic lube
Over filled

Now on the over full issue. This trans is from a 75 Corvette. I have noticed in the T/A that it mounts canted towards the driver which places the filler plug higher on the passenger side. I don't know if this trans mounts straight up in the Corvette but if so that would explain how it could be easily over filled.

Any one else with a thought or experience with this?

Also anybody know the correct fluid capacity for this trans without filling until it runs out the filler plug hole?

Hmmm...... I guess everybody runs automatics?

Mine has an ST-10 . Had the same problem, it was puking oil out the front. Started to just replace the seals and gaskets, but decided to have it rebuilt, while it was out. After seeing the used parts including grinding bearings, I'm glad I did. Something to think about.

Found a spec sheet. Says fill with 2.44 pints. This thing had almost 2 qts. in it. Got it back in and will test tonight.
