Has anyone ever seen anything like this before? I had ran 5 passes with no problems and while going through the pits after a run my car locked the rear wheels and choked down the motor. I was only going about 5 mph, after the car stopped I started it back up and tried to put it back in gear but didn't have any forward gears only reverse. I pushed it on the trailer and took it home, the next day I tried it and had all gears again. It would spin the tires and shift from 1st to 2nd OK in the driveway. I was scared to take it up the road and have it come apart causing more damage that it already had. By the way its a th350. Ant guesses as to what happened?
