I know on my TR3 (with TR6 gearbox when I fit the 3/4" piece of rubber hose on the stick shift ,as others have done to prevent gear shift rattle, it was very hard to get the shifter in reverse. I'm thinking maybe the PO did that mod and that's the issue? Can the gaiter and rubber boot type grommets be removed without removing the carpet on the gearbox on a TR6?
