Good for you guys for changing it. Nobody bothers with gearbox oil. I had the same problem with my windscreen leaking onto my engine. Check your gear linkage cables for play..
Hi Josh. As a Mechanic who did 34 years in the motor trade I can honestly say that I think your 5th gear synchro is at fault. This means a new box or a refurbished, oil won't make any difference mate. Hope you get it sorted. Dave and Rach NB HOLLY X
Thank you 😊 David. That is what dad thought, too. We were hoping to get away luckily, but clearly not. It's good to hear it from a mechanic. It's strange that it's going at 80k miles. Do you know how long it will last and how much worse it will get?
I've got the exact same model of Boxer and like yours 5th gear crunches. Our get around it is to double clutch 5th gear and that seems to avoid or lessen the crunching considerably to the point where it cant be heard. Our van has 140K on the clock and has been crunching in 5th since before 120K so its not gotten any worse in 20K miles by double clutching...........I'd also say that cleaning and greasing the gear linkage on top of the gear box is a must as this area is prone to getting lots of crap on it which can only make gear changes worse if left unattended to........
The problem with it being an ex mini bus you just dont know how many bad drivers have been behind the wheel,it could last for a long time as long as you take your time putting it into 5th,but its one of those how long is a peice of string moments at least you have given it a chance by changing the oil.

I have the same van and am planning a gearbox oil change. How much oil did you put in?
New 5th gear needed.

Good point. Luckily, we don't often use 5th, but I'll let dad know. Cheers for the advice 👍
add some saw dust 😀
We are having the same problem but worse in our Peugeot boxer, can’t get into 2nd gear and reverse. Did you find a solution?
5th gear synchro is gone Josh, had it a few times.
Yeah, that was the next port of call. Cheers for the extra confirmation 👍
Did you get to the bottom of this?
