Hi gang.
I was driving in this morning and revved up to 4000 in 3rd gear and when I tried to select 4th I just got a crunch.So I coasted to a halt and discovered I couldnt select any gears at all. So I switched off the engine and waited a few minutes. Switched back on and hey presto all gears available. Then got some petrol and once again couldn't find any gears. Did the same thing. On and off with the engine and got all gears back again.

Its an MTX75 by the way..
I'm hoping its just a common linkeage problem.
Any ideas.?
Cheers,
Morg.
