TD5 Manual gear selection suddenly gone awkward

Postby Cret » Thu 05 May 2011 7:55 pm

A week or two back I noticed that the gear lever wasn't easily going all the way to the left (while in neutral) in order to select 1st. So I would move the lever left, then back to the middle and then second move left it would move fully to the left.
Can't quite explain but it was as if there was an obstacle in the way of the lever, which moved when you try a second time. This was consistent and a bit annoying.

Other gears were all fine.

Tonight though on my way home from work the other gears started playing silly beggars to when trying to change gear both on the move, and also at a halt.
What I noticed first was that it felt like it hadn't gone into 5th while going up the gears. The lever didn't go as far forward as normal and I thought it wasn't in gear, but it actually was. So I was a bit suspicious but carried on. Then it was notchy anc awkward going from 5th to 4th, and indeed most other changes except between 3 & 4 for some reason.

3rd and 5th were really weird as it seems like the lever wasn't going forward properly to where it would normally be, but was still in gear anyway.
In general the gear changes are notchy, stiff, and not at all smooth, whereas it's been fine until today (except for the first bit I mentioned re' the last week or so).
There is no crunching happening at all. It feels more like an issue with the lever/its linkages or something, rather than say a clutch or synchro issue from what I'd have thought.
To put it another way, once the lever gets where it should be, the gears engage fine with no crunching or difficulty, but it's like something is making it difficult for the lever to move if that makes any sense.

Then just near the end of my drive home (15 miles), the gear selection seemed to improve again suddenly, and the lever seemed to go more into the position where I'd expect it to be for each gear.

So I'm nervous now. Engines I can usually fix given enough time but gear problems scare me.
Have read a few gear related threads on here after a search and some mention gear oil, others mention synchro issues, and others mention timing of gear changes etc.
Not sure any of those things are on the mark in this case given that this has A) Happened pretty suddenly and, B) Not getting any nasty noises or crunches etc.

Am all ears if this sounds like something specific (or not!).
Haven't the faintest if it's even easy to get to the bottom of the gear lever on these to check linkages etc, but I'm hoping it'll just be something like a dodgy linkage external to the box, or even a bit of crud or something restricting the lever?

Thanks in advance for any info anyway!

Sounds very much like the Bias plate and or springs are breaking up or moved out of position, not difficult or expensive fix.
centre console out, and you will see a matal plate riveted to the tunnel, drill the rivets and remove the plate, this reveals a oblong rubber boot, pull this up and at the base of the gearstick you will see a metal plate with a spring either side, this is the Bias plate

It may be worth changing the gearbox oil first, I had very similar symptoms last year with mine (details here http://www.greenlandrover.org.uk/gearbox-update/), as explained in the post after a few hundred miles the gear change improved significantly. Another suspect maybe the bias plate which costs about a fiver.

Thanks for the replies & links guys - much obliged.

Dumb question but what/where exactly is the bias plate? I'll get looking in Rave/google anyway!

I have a suspicion you're going to say they're inside the box, but then to me that wouldn't tie in with not being expensive to fix if the box has to be removed & worked on, so I hope I'm wrong.... :shock:

Just going to check those links and am guessing the answer will be there about above question!

The bias plate can be accessed from above if you remove the central tunnel trim, no need to go digging in the gearbox. Image

Good stuff - had just about got to that via google. I've found a few of them on ebay and they're cheap as suggested. Is it worth getting one that includes the springs as a matter of course?

Mine is a 1999 model, and I've found these ones inc springs for a tenner or so, but they don't say which models they're suitable for....

Ta.

Any idea if that link would be the right one though? I read an article saying the R380 box is on all landrovers from 1996 to 2006 so if that's true it sounds right.
