Greetings! I drive my A3 all the time with no problems. It's got 8200 miles on it. Two days ago, and still today, it's decided to downshift, from all gears, at higher than normal RPM's as you slow down. It's not a major problem but makes for a jerky stop. It's the change in tranny behavior that concerns me. It may also upshift at higher revs, but it's not noticeable enough for me to confirm that. Any thoughts/comments? Thank you very much!

Check the governor. There should be a small filter that feeds oil to the governor. It can become plugged. This will give you almost no governor pressure which causes the tranny to downshift at lower speeds. Also the governor weights can become stuck. Take it out and check for movement of the shaft and weights.

Check the kick-down switch (I assume it has one) is ok.

No, the governor controls the shift points along with the modulator valve (cable connected to the throttle) . The two forces work with and against each other. When you accelerate your pushing the throttle down which gives you more modulator pressure. This is acting against the governor pressure which is controlled by the RPM of the transmission.
