    I have 2 flanges on my exhaust pipe under the tranny pan so I can take the pipe off to change the tranny fluid. I took the pipe off a few days ago to take out the driveshaft and one of the gaskets broke. I can't find one, and i was wondering if I could seal it with RTV? Would that work?

    Hell NO that would not work :)
    Hit up a muffler shop for a new gasket.

    Not even close. That stuff would burn out in about 2 minutes if it lasted that long.

    You can buy donut gaskets at any autoparts store. Bought some at autozone can't remember price but it is cheap. think you will need 2 inch. As the others have stated rtv will not work.

    Should not have to take off pipe to change tranny fluid. I never did on my 89 or 87.

    I have a deep tranny pan and it won't clear everything if I don't take it off.
