Yes it must be a first. Pulled the car into the shop after driving around the block. Went to tern the car around so I could back in to do a little paint touch up on the deck lid where the lighting is better Backed up 6 feet and it felt like I was applying the brakes. Didn't just lock up and stop. Took about 3more feet. That's why I thought it was the brakes or diff. Disconnected the drive shaft from the diff and jacked up the rear...back end spins fine. Put it in neutral and tried to spin the drive shaft....locked up. It would seem to me that if two gears were selected..it would not run in neutral with the clutch out. You would have to have the clutch in. The synchros are all dead center between the gears. No gear is locked to the shaft. They all spin freely.
