Main gear Lever gone vague - bias spring?

I've searched but can't find anything relevant.
Trouble is:- Discovery LT77 main gear lever has gone all "floppy". Instead of resting at the 3rd 4th gate in the neutral position it now falls all the way over in 5th gear position. There's still resistance to going into reverse from a spring but no guidance at all for selecting 3rd and 4th. She who must be obeyed hates this with a passion. I think the bias spring is the culprit. Is this located in the gear selector housing?

Anyone out there know if this can be accessed without having to drop the transmission.
We're talking Discovery 1 here.
If it was the 110 I'd pull the floor and have a look.
Can it be accessed as easily on a Discovery?

On a disco you have to pull the center console out and undo the tunnel cover. It's a fiddly all-day job. There is a tension spring (FRC7414) that may have gone the way of the mastodon.

Thanks for that. Fiddly and all day two words that go together when working on a 20 year old discovery
There's a whole lot of sill welding in the not too distant future too.

FRC7414 is that the same part for a discovery box?

Probably. I got that from the 110 parts book. Just do a search on it at Paddocks or Craddocks or any other ducks you prefer.

O.K. been doing that comes up blank, think there must be different bits in there, more complicated.
Anyone got a parts diagram for a discovery?

Actually, sounds like you are talking about the "real" series 1 Disco....200TDI era. Opening the center console is easy. Maybe 30 minutes (yes, I have personally done this job). It is all obvious once you are in there. Read the workshop manual as it is well explained. The reverse spring is separate from the main spring. I would first assume the bias spring plate has come loose.

Thanks, with your advice & the diagrams I think I'm sorted, just got to dive in and fix it, parts aren't pricey for a change hopefully pick them up tomorrow or via the web.
Brill thanks for the help
I'll post some pics when I tear into it.

It could just be the grub screw on the bottom of the gearstick....(take the casing off that the stick it attached to, and you'll see the top of the selector rod thing, don't know its proper name, and the "cup" that the "ball" of the gearstick. the "cup" is what is held in place with te grub screw)


can you still select gears? if not, then more likely the grub screw come loose (5 or 6mm i think, lock it up with some locktite)

If you can select gears but the stick is all floppy, then one of the springs is prolly broken.

Hi Jim,
It's the latter of the two cases, I'm just about to order the two springs and the base plate, they're not expensive and it sounds like it' a bit of a task to get in past all the trim & sound deadening. Why can't my good lady wife drive a proper Land Rover, it'd be a 1/2 hour job.

Splendid, Mended
3 hour job including welding the hand brake base plate the had snapped in half. There's always a catalog of woes when I start any work on the discovery. Still at least it was a sitting down job & my 6 year old helped in a useful fashion.
