2002 S8 Gearbox Question !!!!!
Morning all !!!!
My 2002 S8 started to play up a little yesterday. We always drive the car in drive mode. We never use sport, the steering wheel controls or even the plus / minus tiptronic controls (or whatever it is called). The gearbox started slipping and the revs would rise but no drive. When you lift you foot off the throttle the drive would clonk back in again. I obviously know this can be a major problem with these cars and an oil and filter change might help but we have now tried driving the car by only using the gear stick in the plus minus mode and it drives perfect. Well that's assuming your driving easy. If you go for a spirited drive and the gearbox tries to change itself it still slips, but on everyday driving with you using the gear stick it's fine. Can anyone explain to me why that is, (ok when your selecting the gear with the gear stick but not when the car decides to change itself), and what that consequently tells me about my gearbox problem ? All help appreciated ! Last edited by Ricky22buk; 23rd October 2014 at 07:52 AM.

That sounds similar to my occasional problem. Did you get some power, so you made progress but with higher revs, or no progress at all?
Mine would actually gain speed and change up through gears if you could give it time, and felt more like the handbrake was on, though revs were higher than usual. A "blip" of the throttle and all returned to normal, but no clunk. I had an oil and filter change some months ago.

Worth checking for fault codes. If bits of the gearbox are spinning at the 'wrong' speeds to what it expects because of an internal fault, it should be logged
As soon as it starts getting thumpy it tends to suggest a definite mechanical fault that will only be rectified by a full strip down :/

Its as if the car jumps out of gear for a second or two and there is no power. It then 'clonks' back into gear and accelerates as normal. It really only seems to be in the first couple of gears, and if you can get to four and fifth it all seems to go as normal.
Unfortunately if the gearbox does dies I can't see us throwing money at it and it could well be the end of a era for the D2 !!!! Faults code some other night when I have a free minute......

Not long, unfortunately - probably a month or so, from memory, before I put it into Chester Auto Transmissions for a gearbox flush, which made it much worse!. I then drove it (very gingerly...) 200 miles to Mackies for a full rebuild, not cheap, but worth it, in my case at least.

Having now started to drive the car myself (it was my wife daily driver) I see that the car is completely fine and trouble free when its cold and its only when it warms up that it gives trouble in the first 3 gears.
Given that scenario would you bother going to the expense of changing the oil and filter or is it still likely to be terminal ? I take on board that tin tin said after his oil change the car deteriorated very quickly !!!! Last edited by Ricky22buk; 5th November 2014 at 11:09 PM.

I would give the guys at Mackies a call, decribe the symptoms and see what they recommend. I found them very helpful in discussing D2 gearboxes (they said that there is no particular issue with them that makes them inherently worse than any other box - as long as you dont believe the "sealed for life" gag).
