Any one have any advice please ! for a while my 2004 dci has had a horrible notchcy gear change recent clutch an hearbox oil change made no real difference so thought i mighy need a new gearbox. Sometime's changes up an down nicley then sometime's it's notchy an wont change smoothly i had a look seam's like play on the top of the selector fork's where the gearchange cable's attach at the r clip's . How much play should be there and if so can just the selector fork's be changed ? It's odd as it's intermitant and not just one certain gear!
