I dropped my transmission, and i am replacing both the front and rear oil seals.

The service manual calls for some multi-purpose grease to be applied to the inner lip of all the new seals.

Isn't some transmission oil enough? I was going to put some MT90 oil all over the new seals to press them in...

Otherwise, can i use some moly grease on them?

Also, would you apply sealant on the transmission cover plate gasket? Isn't a new gasket enough?

Any advice?

The answer is Lithium Based Moly Grease is to be used on the inner lips of transmission seals.

Not on the engine rear main seal. Just use regular oil on the inner lips of that one.

All seals should be pressed in dry (i.e. no lube on the outer parts of the seals.
