crank bearings probally[/b]
great,i take it that's the only place the tranny oil can get through.
i did some resurch today and found .the tranny oil can leak by through the counterbalancer seal on the stator side,the right side crank seal,the two blacke bolts with brass washers that hold the crank bearing in place.someone also mentioned a check valve leaking by.where is that at?and what's it's purpose?i guess i'll tear her down again and double check everything.
