Classic symptoms of a bad master or slave. Replace BOTH at the same time.
Generally the slave becomes "sticky" and puts extra pressure on the master
causing the master to fail internally...no leaks. Fluid just bypasses the
seals. In this case, replacing the master would get it operational, but the
slowly dying slave will cause the new master to fail in relatively short
order (Ive seen the new master fail in 4 weeks). Bite the bullet and do
both. and start the project by SOAKING the slave in a GOOD penetrationg oil
like Kroil every day for a week before even trying to remove. and give it a
few whacks with a BFH to help break free the corrosion that has no doubt
welded the slave to the tranie...the slave is cast iron and the tranie
housing is aluminum. Add in exposure to rain water and road salt and it
welds itself on there quite nicely. lol BTDT!
