Super T-10 leaks
 

I have even drained some lube cause I thought it was over full some way. Every time I take it for a spin around the block oil will drip off the bell housing and form a puddle on the drive. Nope it's not engine oil. I have the BOP seal and the crank area is dry as a bone.
I understand these trans don't have a front seal but use a slinger of some sort. So why the leak?

My ST-10 leaked horribly when I installed synthetic gear lube. It also ate the synchros way too quickly (I was later told by Brian at S&K Speed in Long Island that the synthetic lube was likely the reason). When I switched to 85W-140 conventional, it never leaked a drop and the synchros looked great after several thousand miles.

What type of lube are you running?

Rocky, was yours leaking out the front pilot housing? I don't remember what lube was put in. I'll have to check. What else can cause this?

Mine leaked more from the flanges between the main case, mid-plate, and tailshaft. But it also leaked from the shift fork seals. Are you sure a gasket was installed under the front support collar?
