I fitted my selector back in my car today but found a had next to no movment so couldn't select gears after I removed the selector bar from the gearbox I found it was the selector bar on the box that wouldn't move,the gearbox was given a freshen up about 6 months ago but not fitted its been stored in the position it would be as fitted in the car although it was upright for a while when it was painted is their somthing that could of slipped out of place due to movment or maybe seized? Any help much appreatiated
