Opps ! I think I hurt my car. Last night while pulling it into the garage bay I released the clutch at idle RPM, the car "jumped a tiny bit" and made a pop like a .22 going off. Now the car will not move, I can put it in gear, release the clutch completely with the motor running and can feel (just slightly) the gears turning in the trans. but the car will not move. Had to push it in by hand but it was very tight, almost completely locked up, took all two men had to get in the bay. The brake is off, the trans is in neutral, when we finally got it to move there was a "tight" sound, like a brake was on. Nothing is leaking from any case, brakes are completely released. Any thoughts ?
