Scott, our gearboxes are not tiptronic as far as I know, or are they??? Tiptronics are not sealed for life and they need servicing every 30k or something like that.
Our gearboxes are sealed for life, but if you want to do it especially on a high millage car then MAKE SURE you really use PROFESSIONALS and Audi EXPERIENCE SPECIALISTS.
For anyone who is prepared to travel or lives local to London/Harrow I STRONGLY RECOMMEND this guys

The amount of experience they've got (Chris especially with A8s) is really impressive. They are just TOP BOYS.
I service and repair my car with them for around 3 years now and genuinely I can't even think of one bad thing about them, hand on my heart...well, there is one thing, not very comfortable sofa in the reception area
But on the serious note, I've done all sort repairs, from camshaft tensioners (both), cambelt, rad replacement, suspension, exhaust, longlife service, ac service, alternator belt, water pump, electrical faults and never ever had any issues with them.
Plus they use only genuine parts for very good prices and the main London stockist which supplies all Audi dealers in London and surrounding areas is just next to them, so any part any day Mon-Sat will be with them within 30min.
I can't remember if that was a service or just filter+oil change (dont know what else you can service there if gearbox is running fine) but it was £250 I think (or 350?? I'm almost sure it was 250)
Just check About Us section to find out more about them.
If actual cost will be less than quoted because of less labour involved, they WILL charge the correct amount. If your car is ready early, they will be on the phone to you to take car away to make room for another one (there is outside space of course) as in 3 years I've never seen a quiet day there, ever, and I've been there many times, sometimes even for a chat about some issues which I couldn't figure out.
They were recently adding Lucas Transmission maintainer for me (great stuff and it works), and not every VAG specialist will tell you, but even that requires gearbox oil temp to be something like 51 degrees, and they always follow this procedures as you would expect from specialist, where some would just add it, charge money and wave you goodbye. Not sure if temp requirement is crucial, but its there for a reason
Sorry for the write up, but I believe that real professionals should be always reviewed well...and they do full rebuilds as well, no matter if its a gearbox, engine or whatever.
