BA Falcon Manual ute keeps throwing 5th gear

[WattaBA]

Gday, 

My 2002 BA MKII Ute has decided recently it doesn't like 5th gear anymore, still shifts into 5th however after a random amount of time (sometimes instantly, sometimes after a minute) it spits it back into neutral. Anyone know why this is happening? Is the clutch on its way out or is it potentially time for a new box? still shifts and holds every other gear fine.

Cheers

Have you got a 6th gear? if so, don't ever use 5th  

 

if not, then yeah, you probably need to have the gearbox either re-conditioned with new synchro's etc or repaired some other way or completely replaced.

Never had one of these boxes open, I had this symptom on an 06 Pajero after 300,000km, but I think it was 1-4, not 5 or reverse. Ended up being the countershaft had hammered it's bearings into the aluminium case over the years and built up a bit of fore/aft slop. This shaft had the selector rings on it and could now move relative to the selector fork and shift itself out of gear. Reshimming fixed it for another 200,000km. It would send the gearstick flying, give you a nice rap on the knuckles.

Hmmmm yeah seems to need some level of reconditioning.

 

An occy strap should get you by for a while.
