I've had my 97 D2 A8 for about 18 months and love it. The past couple of months the auto shifting had become more vague and inconsistent, at certain revs it would shift down, then back up, then down again etc. So I finally took it to my mechanics and they changed the gearbox oil and filter. It is now even worse.... As well as even worse shifting behaviour, it whirrs on initial selection in lower gears - and a couple of times has packed it in all together and goes into limp mode. This seems to be caused by heavy braking, though obviously is not something I have tried to replicate.
So is this the end? I have heard horror stories of multi-thousand pound gearbox rebuilds and I'm not really sure I'm committed enough to invest that sort of money in to it... Is that likely what's required or is there an alternate fix. I really don't want to scrap it as other than the gearbox it's really a fantastic car in great condition...
