Jere,

Drain the oil from the tranny and refill with Redline MT 90. Very
superior stuff. It will help the shifting.

Second, if the slave clutch cylinder bolted to the the tranny is leaking
or wet, replace it and bleed the clutch line. That will probably take
care of the problem.

If it does not, then you will have to have the tranny pulled and torn down.
