After just over a month of ownership, my 2004 L322 4.4 V8 looks like it's going to need a replacement gearbox.

For the past few weeks I've been having issues with the gearbox, such as huge clonk when changing up from 1st to 2nd, as well as intermittent juddering at all speeds/gears, and rumble/vibration around 50 ph.

Took it to a friend (Mechanic) this weekend, and he thinks that the the clutch plate could be the main issue and would need replacing. Subsequent to this, I've called Bristol Transmissions and based on the phone conversation with them they have advised a replacement box (Recon), which would get a full 1 year Warranty at a cost of £2400 + VAT

There's always a risk involved when buying any older car (Especially a RR), but I must admit I didn't expect to be faced with a bill so early at not far off what I paid for the car!

It's making me think that the seller mislead me (eBay private sale) and perhaps did something to the gearbox, as when I test drove it, I couldn't detect any of these symptoms and found no faults with my IID tool.

Anyway, any thoughts from any of you on if I have any options, or does it really look like I have to stump up for a new box?

I'm putting up with it at the moment, using manual mode when it's cold and driving like a nun, and so far it's helping, although have had two occasions this week when I had transmission fault and one with complete failure of any gears - all of which were fixed by reading and clearing faults.

Thanks in advance

Before spending that sort of money it would be worth checking the transmission has enough fluid and perhaps changing the fluid, those symptoms could be sympotamic of low or bad fluid.

Thanks Kesbo, sorry I should have added that we checked all fluids at the weekend and all are clearly recent and at the correct levels  Iggy/Ieuan

Any receipts suggesting whether the right fluid was used? It could be some generic trans fluid was used and the gearbox doesn't like that. However, like your original post indicates there maybe is a problem and the fluid was changed but didn't solve the problem. Good luck!

As it's still working I'd be inclined to invest in a gearbox flush (look up "Bodsy".)

The previous owner may not have been aware of impending doom - my L322 (admittedly a TD6 with the rubbish gearbox) went from "perfect" to "scrap" in less than 50 miles.

Fatty off roader was bought with a known gearbox fault, same issue as yours, I managed to coax about 9 months out of it before having to replace the gearbox... I changed the oil and it made it slightly better but it didn't last...

I used a second hand unit, a bit of a gamble but only cost £500....

If you keep it and change the gearbox you have to budget for a new torque convertor, oil cooler and lines, your old ones will be full of swarf and will wreck the new box if not changed... It is virtually impossible to clean then out successfully...

Personally, with the issues you have and clean looking oil I doubt a flush would do much good....

Sorry for the doom and gloom... Pete

Personally I would pause before you commit to spending anything and give the whole car a very good inspection.
You haven't had the car long, it's easy to push ahead and spend lots of money on a new toy but it is nearly 20 years old and if it is immaculate and well maintained it may well be worth putting the money into it. However it is also at the point where it could become a money pit and the more you put in the harder it becomes to stop spending. Any car that age is just one big bill away from the scrapyard.
I suggest you have a good look for corrosion and also consider anything else that needs fixing then think about the big picture and consider if you want to cut your losses.

If you have the facilities & you’re handy with a set of spanners you should consider remanufacturing your transmission yourself. The hardest part is getting it out of, and back into, the vehicle. Tearing down, repairing & rebuilding the ZF 5HP24 transmission really isn’t that difficult. This would massively cut down the cost.
