4th gear popping out (1996 Ducato 2.5 TD) (1 Viewer)

[jamieBG]

Hi all

Heading down to the New Forest yesterday, and 4th started popping out of gear of its own accord.

Travelling along, it went into 4th normally, but then after a while the gear stick jumped out of 4th with an accompanying growl of revs. Sometimes I could grab it and pop it back in again, other times if I tried to re-engage it just popped out straight away again.

It only happened 4 times on the way to the New Forest and back again from Andover. Bit of a surprise. All other gears behave fine.

Any suggest what the cause might be? And what is the course of action?

Many thanks!
Jamie

loose or worn selector is a possibility. the bolts sometimes work loose so may not be massively expensive.

First check should be the linkage on top of the box. You need to be sure that when you move the lever to 4th the selector shaft sticking out of the gearbox is fully in the 4th gear position. Once it's in the correct position detents on the internal selector shaft and within the 4th gear synchro hub hold it in place (think spring, ball-bearing, recess). A simple check is to put it in 4th at a standstill (engine stopped) then make sure the shaft on top of the box has rotated fully into position. If the linkage is in generally bad shape (lots of slop / play) fix it before going any deeper.

Thanks for the replies.

The older threads all pertained to 5th gear problems, which seem to stem from 5th being an afterthought on an older 4-speed designed box, so I skipped those.

Sadly, it doesn't look as easy as any loose/worn selector. So the box is coming out and is being sent to Broken Link Removed next week for an exploratory (for repair or recon box, depending what it looks like). She's getting a new clutch while the box is out too as it is rather tired.

oh well £££

:thumb::thumb: Always a good plan!

see what other preventative maintenance jobs can be done whilst its apart. most of the cost is in the labour pulling it all out so it makes sense to do clutch etc

if it was me i would service the clutch cylinders and replace the fluid too
