I am re-sealing the transmission to stop big oil leaks. The largest is the joint between the gear box and the bell housing. It looks like the box has been apart in the past, probably when the OD was changed. Which gaskets need sealant? And what sealant is good to use? It seams that the bell housing shouldn't use a sealant since it uses crush shims to hold the input shaft bearing/main shaft tight, and you don't want to increase the gap. It did have a light coat of regular Permatex on all gaskets previously...
