Thread: Disco 2 manual gearbox- strange behaviour!

I pulled away in first with plenty of revs, nothing excessive though, then went to select 2nd, and it wouldn't go in. I tried the other gears and couldnt get any. The lever could move side to side ok but wouldn't move forward or back into any of the gears. I tried declutching and still nothing. I was coming to a slow stop and was beginning to panic as the boat was still across the junction. I thought the gear box had died.

When I came to a stop I was able to select the gears as normal and then drive away as if nothing had happened.

I was pretty nervous for the rest of my trip home.

The car has 200k and has no other gearbox or clutch issues. I changed the gearbox oil a few thousand K ago to the LR spec oil.

Anyone any ideas?

Cheers

Could be the beginning of the slave cylinder going, it may have an air pocket, that will stop you changing gears.

Someone with a bit more knowledge may have a better idea.

assuming the clutch fluid level is ok....

the master cylinder will be starting to leak back past the primary seal.
