Ah, not so good then ... back to my dilemma, whether to get a separate transmission fluid cooler or just replace the existing radiator.

Experts please ...

Advice from another forum expert suggests just getting a new water/oil radiator.

Well, now know the damage:

Re-manufacture gearbox, including removal/fitting and torque converter £2350

Replace bearing and seal on front diff (leak), including removal/fitting £460.20

Replace input shaft in transfer box, including removal and fitting £472

Replace rear diff oil £25

Remove and refit new radiator (to prevent future oil contamination) £428

Total £3735.20 plus VAT (£4482.24).

24 month warranty.

All in all an expensive couple of weeks for the Disco as I also had the track control arms and bushes replace, the steering realigned and a worn tensioner replaced just before Christmas.

As I have mentioned elsewhere I am considering having a crack at getting Land Rover to cough up for their bad advice re oil change intervals on the gearbox: http://www.disco3.co.uk/forum/topic155140.html

Bristol Transmissions have certainly been very thorough (I asked them to be so) and I hope that the vehicle will then be good to head towards the 200,000 mark, with regular engine and transmission oil changes.

I would certainly say to anyone who is driving one which has done 50K miles and hasn't had the gearbox oil changed, to consider doing so, and if doing a lot of towing like I do, as soon as you can.

assuming there is no water in the oil, I would ask for your old radiator back and sell it on ebay or here.

I guess they want it done to satisfy the warranty

Cheers Pete, but that's down to me wanted to make sure that having got a new gearbox that the current radiator doesn't fail and let water into the gearbox oil. I intend to keep the old bus until its done at least 200K, maybe 250K miles.

Drove the car home from Bristol on Friday. Quiet as a mouse. Drove lovely. Looking forward to getting the tintent on the back again soon. Bristol Transmissions were very professional and dropped me off at the station and picked me up again on returning. Very impressed.

I had exactly the same experience with Bristol transmissions - very good.

My gearbox and TC were replaced at 88,000 miles.

I am now doing a half-change (drop the oil in the sump and replace) every 12,000 miles.

Whilst it may seem excessive, you can feel a difference in the way the gearbox changes after each oil change. So there must be some deterioration of the oil, even in just 12,000 miles.
 New gearbox & TC, 2 x front wheel bearings, belts changed, new oil pump, new battery, new rear prop, new front prop, new front diff, front arb refurbed, front cv boot kit, egr blank and BAS software patch, full rear suspension / drivelive rebuild, LED trailer light fix, split charge.
Never had a 107, 90 or 127, but have had most of the rest!

Awful bad luck that Compusmentis, how things get a little less expensive in the future!

Quite Thumbs Up

Its done 110,000 now. I hope that the current work will set it up for the next 110,000...

Bristol Transmissions were slow when they did mine last year. Lent me a tired old Passat which was better than walking for over a week. Just. A 6 month, 12k mile warranty given for the gearbox refurb. Found worn input splines on the transfer box too. Changed input flange and the transfer chain.

Now, 25k miles later the cattle grid vibe is back. Had a flush done last week at the service and, so far, vibe is gone. I wonder for how long.

I do wonder whether a new gearbox would have been a better option.
