I just changed my automatic tranny gasket on my 84 Westfalia that I just
bought a couple of weeks ago and it is nothing to be worried about. As
others have said, the gasket tends to be difficult to fit because is very
"floppy". Mine came folded up in a box along with a new filter and filter
gasket ( around $10 from Van Cafe). I removed the ATF filler tube first to
drain most of the fluid, then removed the pan to get the rest. Clean the
pan lip and the groove in the tranny where the gasket fits well. Now comes
the tricky bit. No matter what I tried i could not get the gasket to stay
put on the pan while I tightened the bolts. Unlike most gaskets it does not
have "ears" that the bolts go through to hold it in place. Since it was
folded up it was not perfectly formed, nor did leaving it in the sun make
it so. It just would not stay put in the pan. Solution is to use some
gasket adhesive to hold the gasket in place (careful not to get any on the
inside of the pan, obviously). Once I did that, everything went smoothly. I
also replaced the filter and filter gasket which is very simple to do -
just unscrew two phillips head screws in the filter cover to remove it and
its gasket.
My tranny is losing fluid because there is a crack in the housing,
apparently a fairly common thing. With full fluid the transmission works
fine. I'm planning on fixing it with JB Weld as soon as it stops raining.
You might want to check if yours has the same issue.
