ZF produces these "fine" transmission for our A8s/audis... but why do they fail so soon... i mean u figure a car (A8) that cost $80+K would have a transmission built to last the life of the car!!!

now i know some of u guyz blame the "programming" of the transmission, but if the programming is set to leisure/grampa mode why would that kill the tranny faster than a sports mode programming??

do other car manufactures that use ZF transmissions suck as well????

I might have more info on our car soon.

I am looking into a rebuilt valve body.....I'm almost certain that's it.

If you could replace it with a rebuilt unit for $600 or so, it wouldn't be so bad.

But yes, the reverse seal blows out, etc. which requires a rebuild.

The two that I have heard of went more than 250,000 miles before needing rebuilding.

I have a 4HP22 with 208,000 miles in a 300TE that is still very strong

Just a note, running on higher octane seems to make the tranny shift better, especially better upshifting. I changed from 89 to 92/93 octane and I enjoy the car much more. I has lost a lot of it's doggish-ness. [Although I know the tranny is still a weak point.] Lesson learned regarding saving 10 cents a gallon.

Are you going to get a rebuilt stock VB or are there updates and such available for early VB?

The ZF transmission on my (sold at 75,000 miles) 540 was rock solid, the one in my 745 looks also very strong, never heard of any transmission problems on any BMW.
