1992 Range Rover 3.9 EFI - Vibration in 3rd

Evening,


I own a 1992 2 Door Manual. This has the LT77S 'box.

I have an odd vibration/juddering when pulling in 3rd gear. The other gears pull fine without this symptom. It's only in 3rd gear and doesn't matter on engine load. Usually I can't feel the vibration any more over 4k, so more pronounced a low revs. I feel it through my seat, not the steering wheel. After changing to 4th, all is well again.

I have serviced the gearbox (inc. filter) and the old fluid was old but not black. The drain magnet was also acceptable in my opinion, as was the extension case's filter. There was nothing to suggest shards of metal in the system.


The only other issues I've noticed with this 'box are clunky changes from 1st to 2nd, and reasonably large clunks/backlash when disengaging drive in 1st if load is on the system (up hill etc).



Any advice gratefully received.

- Richard
