Hi guys,
My 4.8 2022 GU started to have a 4th gear crunch when shifting from 3rd to 4th. Vehicle odo is on 3000kms only!
I know this issue is popular with GU Patrols, but I can't see a 100% solution..
Does anyone know how to solve this problem?

Try changing old oil out with new Castrol VMX-M with Nulon additive. Also oil might be contaminated. If all else fails, then unfortunately it’s a rebuild job. Synchros are excessively worn.
Have you tried double clutching as on a none syncro box? From 3rd to 4th; Clutch in, gear to neutral, clutch out. Clutch in shift to 4th, clutch out. It might work and it gets easier with practice. I was doing it with my Old Trol while I was looking for a fix when it was crunching into second while cold.
Yeah but its a pain to do this all the time. I have to give the throttle a blip when going from 3rd to 2nd also. The box has done some 450+ thou, I'm just waiting for it to let go, Hopefully soon as I think the release bearing is shot and I don't want to do the clutch and not the gearbox. Well I don't want to do either really but...
