1974 bug auto stick

I bought a 1974 standard bug with an auto stick trans. The car has been setting for at least 9 years. I have replaced the plugs, condenser, points, rebuilt carb, new fuel pump and now the motor runs fine. My problem is the trans. I have replaced the 12mm hoses from the carb to control valve, control valve to can, from control valve to trans pancake and a small hose from control valve to carb. The car is up on jack stands off the ground. The car will go into gear sometimes and other times it won't. I get a grinding sound like the clutch not pushed in on a standard drive. I have adjusted the points on the shift rod, clicking when engaged in motor compartment sounds good. I did a test on the pancake, took the hose off at the pancake (car not running) place thumb over the nipple hole and could not pull the lever back, took thumb off hole and pulled back on the lever, placed fiinger over hole and it would not go forward, so i figure the pancake is ok. can anyone tell me what else i need to do. thanks
