Steve, the lower plate cannot practically be removed with the ZF in place.
There are two long bolts that will run into the lower frame rails when you
try to remove them. The cover cannot be pulled without removing the two long
bolts. Raising the ZF... and engine... enough to allow the bolts to clear is
as much (or more) trouble than pulling the transaxle.
And if you do somehow get the lower plate off, be aware there are precision
spacers between the cast aluminum ears and cast iron side plates on both
ends of the 2 long bolts. Shuffling the spacers or leaving them out can allow
enough space to crack the aluminum or iron ears as you try tightening the
bolts to stop yet another leak.
Finally, the gasket between the lower plate and ZF case is special, sold
only by RBT Transmissions (and most parts vendors). Do not try making up your
own gaskets. Normally, no gasket cement is needed anywhere in the transaxle.
Your choices are to live with the leak, or try SLIGHTLY tightening all the
lower cover bolts without stripping them, or draining and pulling the ZF out
of the car, flipping it upside down, then working on the cover/gasket
problem. If by chance you changed from ZF's preferred old-style lube to a
synthetic, seals and gaskets will sometimes develop leaks with synthetic lubes
where none existed before. So returning the assembly to old-style 80W90 might
also stop your leak.
If you intend to work further on your ZF, most vendors and the POCA Store
have an overhaul manual- either paper or on DVD, describing all the parts,
the torques needed and guidelines for safely working on this $7000+ precision
instrument. Good luck- J DeRyke
