Working on the 69, 302 with a C4 that leaks. Changed the shifter rod seal and pan gasket and it still leaked. Waited a couple days and then leaked like crazy. Looks like now, one of the leaks may be from the gasket that joins the tranny "main body" to the rear-most portion that contains the rear seal of the tranny, the portion that the drive shaft yoke slips into. For lack of the proper nomenclature I will call it the tail shaft housing. If we drop the rear tranny mount, drop the drive shaft, could this rear houshing be slid off the tranny to replace this gasket?? Hope I am being clear enough on where the possible leak is, it is definately not from the rear seal that the drive shaft yoke rides in. Just read some recent posts about checking the vent tube and the fill tube for leaks also. Need to get it up on jack stands and crawl underneath with a light today to identify where it's leaking from exactly. Any other suggestions would be appreciated too. For example, if the vent tube is leaking, what is the fix for that portion, an o-ring or something?? Thanks in advance from the transmission rookie!!
