Gearbox sticking in 3rd

[daniel7000]

Every now and then my gbox gets stuck in third gear and it's very hard to pull out. Someone told me the synchro was shot.
I would have thought if the synchro was gone it would make it hard to get into gear not getting it out of gear.

Any ideas?

86 Troopy.

Thanks.

could be a syncro or could be in the linkages. Time for a rebuild. Given how old they are now you could probably get a used box from a wreckers pretty cheap.

Fix it (or replace it) before it stays in third. Not fun driving in traffic starting in low range and grinding into high range. Although that was a 4 speed in a 45 series ( I replaced it with a 75 series fiver). I would assume it will end the same for you in time.

Thanks for the replys. Today I dropped the box out and took off the top. Was rushed for time so just had a quick look. The brass syncros look rooted on the third gear syncro.
Will pull out shaft and inspect them properly when I get the time. The gears all look like new. Anyone know the best place to get parts for these boxes?

Thanks

Try your local bearing joints, CBC or something.
