Transmission problem
1994 Other Saturn Models 4 cyl Front Wheel Drive Manual 210K miles

I have replaced the clutch master cylinder and the slave cylinder with a new prebled kit in my 1994 Saturn SL1. It still drives OK for a mile or so and then when I stop it will not go into any gear. I have to shut off the engine and put it into first gear and restart the engine before I can get the car moving. When the engine is started the car jumps like the clutch is intermittently catching. Once the car is moving I can get it into the higher gears. When the car sits overnight it will do the same sequence. What is causing this problem? I would like to be sure before I change the mechanical clutch parts since this requires pulling the engine and transmission on this car.
Thanks for your help.
