T150 main shaft seal?
My t150 leaks the oil in to my dana 20 case. I have been researching this for a while and came to the conclusion that the rear main shaft seal must be lekaing, because I have all the holes in the back of the trans plugged. What my question is, can you replace the main shaft seal with out pulling the trans apart, ie: pulling the main shaft? Can you pull the bull gear off the shaft and install the seal that way or does the trans need to be pulled and gutted? I have searched here and other forums with no clear answer.
