My 02 is starting to downshift by itself. It only happens at low speeds like in traffic and after it's warmed up. But it doesn't happen all the time. If I can keep a good pace it's fine.

Basically it will downshift from 3rd to 2nd and won't shift on until I run the RPMs up to 4500 and it jumps into 3rd. Going to 4th it does the same. But I can stop at a light and get a good aggressive start and the shifting is fine. I've gotten to where I use S mode in traffic to make the car shift correctly.

It was doing this about 2 years ago and then Audi had a transmission recall. After the recall was taken care of, no more shifting issues. The recall was for a stretching shifter cable and I was hoping that was the cure.

I called the dealership that did the recall repair and they said all they did was add the part stated in the recall. It didn't have anything to do with fluids or adjustments of any kind.

I'm thinking it's a vacuum issue or something telling the computer it needs to shift. Would this show up in a diagnostic if I took it in?

Any ideas appreciated.
