5th gear jump/pop out
 

Only done it a couple of times, and can't seem to replicate what ever caused it, but was just wondering wear to start.
Looking on net could be a loose nut in box on main shaft, but was wondering if anything else could cause same problem before pulling box to bits.
Anyone had this problem how much cost to resolve it

Still drives fine clutch and box same as ever

Mine has the same problem mate. Been in the garage since Tuesday. Will give you an update when it's all done and let you know the cause.

Could be the 5th gear nut has come loose

Ignore me lol I have just reread your post

All done. 1st and 5th synchro were knackered and replaced. The shaft nut was loose as expected. What I didn't expect was a £750 bill though - and that's cash for no VAT.

:cry:

should have tried api

I've read a few of API's posts, don't think once I'd put on the cost of a tow to API there would have been much in it.

And the fact that the box was out and stripped at Extreme Scoobies before I knew exactly what the problem was.

Happened to my MY00 Turbo 2000 back in 2003 kept popping out of 5th gear on motorways, thought it was just a nut that needed tightning in the box, But on inspection it had stripped the gears, needed a rebuild at a cost of £1800(bearing in mind it was 2003) car was only 3 years old!!!

Ouch… don't like sound of that,

Box out, sent away.told loose nut and 3rd washer breaking up or somthing, part no longer available as been upgraded, so change 3rd n 4th gone for 2weeks £850 bill later put bk in no 3rd or 4th. All out again gutted-miss my car

wtf - at least you will get good at doing box/clutch changes
