Transmission leaking internally.
So my clutch exploded last week and just put a new one in. I noticed a large amount of oil inside the bellhousing. I cleaned it out and was looking for a crack and didn't see anything. Replaced the rear main and finished the install. After 60 miles of driving I noticed it was slipping again so I took it easy and let it sit over night. This morning I put it in the lift and drilled 2 holes in the bottom of the housing and about 1/4 quart of gear oil came out. Do you think my input shift seal is no good or could it be something else. It's a p11 base. I also swapped out the axle seals and those are good. Any suggestions?
