hi all. I put my car in for a full service last week and he also replaced the clutch cable. All seemed fine but now when i try and put it in reverse i get a horrid crunching. When i first get in the car its fine, but after a while it seems like i have to force the gears as they feel stiff and when i stop and try and reverse...crunch! I am currently 300 miles from home and everywhere is shut! Any ideas?
