The sucky part was that, since the ATF was "lifetime", if I changed it and it messed things up, warranty coverage would be very iffy. But if I waited until after the warranty expired, it was probably too late and I'd have been better off just running it until it no longer ran. I change the gear oil in my 993 every two yrs. because it's cheap and easy, relatively speaking. Not so on those auto/tiptronic Bimmers. The ATF is something like $17 per qt. from the dealer.
hmmm..... I have NEVER changed the manual trans oil in any of the 15 or so stick shift cars I have owned over the last 28 years (including 4 high mileage Porsches and two high mileage BMW's one of which now has accumulated nearly 320,000 miles). Same goes for rear end oil where applicable. Of those 15 stick shifts, only 3 ever required replacement of the clutch.

I did change the ATF in my POS Audi auto though only because the trans cooler sprung a leak.
