Sounds like the same problem i had with mine ,easy enough job to do ,just a sod to get to the cable ! go for a cable change if you can,sods law the repair will fail in the middle of nowhere,make sure the new cable ends are securely popped over the ball joints on the gear box levers as they can be a very tight fit, and give the impression of being on , only to pop off a few miles down the road-oh how i laughed! :angry2:
