Raccoon 0 Posted October 25, 2014 Recently when changing from 1st to 2nd I get a crunch, but this doesn't happen from 3rd to 2nd etc. This doesn't happen every single time, if I change into 2nd very gently and slowly I can usually avoid it. Anyway I'm just curious as to what may have caused this, and what my options are to resolving the issue. Cheers. Share this post Link to post Share on other sites
selfyyy 4 1 Cars Posted October 26, 2014 Sounds like a synchro issue, may just be worn? Could try changing the gearbox oil to see if that helps.. Share this post Link to post Share on other sites
Raccoon 0 Posted October 26, 2014 Thanks, any idea of how much the repair would be if changing the oil doesn't help? Share this post Link to post Share on other sites
mikeyd 13 Posted October 26, 2014 if its got the right oil then it depends if you can rebuild it yourself [diesel boxes are a good donor for the sychros as they dont get thrashed/abused as much ] does it do it if you adjust the clutch up slightly?and is it better/worse when the box is cold [oil issues/grade ] Share this post Link to post Share on other sites
Miles 331 1 Cars Posted October 27, 2014 Depends on who does it, New hub's are around £185.00 each, Bearings, Seal's, Cleaning and it's not cheap, I do however have good used hub's at £40.00 each but with bearings etc your still looking at a good £200.00 Share this post Link to post Share on other sites
Raccoon 0 Posted November 3, 2014 We've adjusted the clutch up and it hasn't made any difference, and it's the same regardless of whether the box is cold or not. Thanks for the info guys, I'm gonna have to mull this one over, I'm starting to wonder if it's worth investing any more money into it, it's been nothing but a burden as of late.

lando9000 2 Posted December 13, 2014 I wouldn't be 100% but it could be a thing to look at the gearbox/engine mount. I was advised with our that the engine was moving so much that it was throwing the clutch cable out and jerking it when it moved. We haven't got our back together yet so I can't confirm but it's something else to look at.. Share this post Link to post Share on other sites
Rams_gti6 12 1 Cars Posted December 14, 2014 With you saying it can be selected slowly,that would point to synchros. I had this similar issue. I went down all the easy avenues but it's more than likely the box needs either rebuilding or swapping. Share this post Link to post Share on other sites
