gear box oil
do you have to change the gear box oil at all at any time???? If so when should this be done. It's just that my car is in for a check over tomorrow before warranty runs out,and i'm going to get a few bits done whilst it's there.ie: oil and filter..... I'm on 79000 at the moment. Thanks in advance, uk S4 with AMD remap,bailey diverter valves,Miltek exhaust,K & N induction kit.......

Audi says its a lifetime fluid but many people here (including myself) have changed it.
I changed mine around 60k miles. For the transmission, most use Redline MT-90 and for the rear differential, Redline 75W90 is most common.
Make sure you use a GL-4 spec oil for the transmission and a GL-5 spec oil for the rear differential.

FYI - follow what Dave says about the oil specs - the GL-5 stuff will corrode the non-ferrous metal
parts in the tranny (like synchros), and that is why you must use GL-4 stuff only. Many in the US have reported inproved shifting characteristics with such an oil change.

It felt *slightly* smoother.
Not a huge difference at all. And probably more due to the fact that the fluid in there was 60k miles old.
I did it more for maintenance reasons than to change the shifter feel.
