I generally use Hylomar on gaskets, unless it's a high temperature
application like an exhaust manifold.  Seals very well, is easy to apply,
and easy to clean up when the joint has to be disturbed the next time.
Frequently it even leaves the gasket in reusable condition.

Unless you don't have a gasket, I would suggest staying away from the
various gasket replacement products, especially silicone RTV, for places
like gearboxes and engines.  It's very easy to have some RTV squeeze out
inside, where it may later break off into long strings and block something.
Other products, like Permatex #3, don't have that problem, but are still a
royal PITA to clean up the next time the joint must be disturbed.
