What year is it? The A8 boxes, particularly later 5-speed, are notorious for doing this. ZF transmissions do a "Super service" which completely cleans out the internals but may not stop it dying, but the general consensus is that if it starts playing up like this a total rebuild is the only way. Sorry!

It's produced in 1997 so I think it does have the bad gearbox.

Thanks for the suggestion regarding the cleaning of it!

I've read a lot on the A8 forums recently about it since I've recently bought a 1998 4.2 A8 and whilst the gearbox generally behaves itself, there is the odd flutter. Consensus is that the only way to prevent it is to change the oil every 30/40k miles from new. Changing it late on in life is considered to be counter-productive. I think really it's just luck. I have found a place which appears to offer a completely remanufactured box fitted for £1.5k which is not as horrendous as some I've seen.
