[bunter]

has any one else expirienced their GQ jumping out of 3rd gear ,it only hapens when i back off ,,i have a 50mm body lift and i thought it may have been the boot pulling it back out of gear, but i removed it and it still happens ,, any ideas what it could be
ive been told syncro hubs worn but before i put the box out id like to hear from you guys of any other likely causes

thanks Bill

mines done it a few times on steep hill descents in low range, never done it on normal driving 150 000klms not even high klms, so would be curious to find out as well

Check if the box has detent springs. Rovers have them . If they loose tension jumping out of gear is common.

On my gq i had the same problem except it was second gear . my fix was to pull the gear lever boots and plate under neath it off , pulled the top plate off the gearbox ( i had no bodylift and did it so with 2 inches it would be easy ) and found that my shift fork in the gearbox was worn and not fully engaging gear . this can be diagnosed by pulling the side plate off the gearbox passenger side and putting it in third gear ( or what gear it pops out of ) and looking through the plate to see if it has fully engaged the gear . Just what i did hope it helps .....

Its very common for shifter forks to wear on GQ box's mostly 3rd and 2nd
gears the synchro hubs are usually ok.So it's just a matter of changing lid,also check the cups the gear stick ball sits in if worn replace them they cause problems to.
