2000 Audi A6 4.2 Transmission Problems

[jross144]

Hey Guys,
I have an 2000 Audi A6 4.2 and I have transmission problems.The car wont move at all.Whenever I charge the battery it drains almost immediately.Is there anyway I can purchase a different year transmission and put it in the car? If so what would I need in order to do so? Thank you for your time.

Sorry. Not really. In the US I think you're stuck with that transmission from that particular year; or possibly an 01' . In 02' there was a change in the way the trans works, some hardware and the TCU, they added "S" sport mode and different Tip shifting, I can't say I know of anyone who's put the later trans in an early car. Maybe it's less work than I think, but.. definitely more work than just using the right trans.
So, you're in for a rebuild it sounds like. There's a chance it could be one of a few other problems, like broken axle or something, but the transmission in that car is known to FAIL. Alot.
As far as charging..it's hard to tell without a bunch more info. Scanning the car with a good OBD interface (like Vag Com) would tell us more.

I put a 01' transmission in our 02' Allroad with no issues. The 01' did not have the "S" gate and that function works as it should in the 02' I boil it down to that function is controlled by the TCU.

Maybe it could done? Scotty would know possibly. But, the Allroad trans is a totally different thing also. 5hp19 vs 5hp24 for the 4.2 .

Allroad has one auto trans for the 2.7. The A6 4.2 had 4 different ones If I remember correctly.
