The SS got a new ram clutch/ slave cylinder install last week. today i drove the car around almost all morning. i parked it in the driveway and when i came back to move it, i pushed the clutch in started the car and went to put it in gear and it wouldn't go into first. while running and pushing the clutch in the car won't go into any gear. if i kill the engine it will go into any gear i select. if i put the car in first and start it, it will move. if i put the car in reverse and start it it will roll. the only thing that wasn't changed is the master cylinder, does this sound like a master cylinder problem. i can see it under the brake booster, how hard is it to change?
