It's almost funny, actually...one of the cars has been sitting for about a year - heated indoor shop - and the only way to select gears in the A833 now is engine off. Clutch does not release. It'll start in gear, though.
Linkage fine, nothing was changed in that time except a starter replaced, pedal moves normally.
I'm thinking the disc is stuck on the flywheel or pressure plate or both; and the only way I can think of so far to free the disc is to warm the car up on stands & in gear and then shock it loose with the brakes.
Anybody have that happen before?
