2002 S8 Gearbox Question !!!!!

[Ricky22buk]

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 !
