Driving along today at around 40mph, went to select 5th, felt a bit dodgy and when i backed off the throttle it popped out of gear. When i select 5th gear it gives a little crunch like the synchromesh has departed and 5th gear still pulls fine if i hold the gearstick in place. But if i let go and take foot off throttle then it pops out again.
Every other gear is still ok.
Anyone have any suggestions as to what could be the problem?
Looks like this weekend will be spent removing a gearbox
Thanks in advance
