My mate plugged his computer into the car and noticed the left rear wheel speed sensor wasn't picking up direction till 45 mph and it read it as going backward. Bare in mind I have had each wheel speed sensor go and had changed all 4 I didn't expect to have a problem. This didn't throw up any codes or any dash warnings.
I changed the sensor AGAIN and the box has been fine since. I had another guy message me about having the same problem and the WSS turned out to be the problem.
So. Plug a computer in and see what your wheel speed sensor are saying.
Hope this helps

I will test this theory tomorrow on my 09' DCT tomorrow pending if my parts department has wheel speed sensors on hand.
