2013 T31 gear box and clutch Pretty sure my exxy needs a new/ fixed gear box. 5th gear is slipping out of gear under load at freeway speeds. Not interested in doing this myself and annoyed this had happened as it's only got 120k on it. How much do you think I'll be out of pocket to get it fixed? Thinking I will replace the clutch plate whilst I'm at it and the box is being dropped out.
