The future is cold and bleak

Since getting the RS6 chipped I have been having problems with the transmission slipping / not fully engaging properly while under half to full acceleration.

I scanned the car this morning and found this – 18034.P1626 Data-bus powertrain: missing message from transmission control.

Theory at the moment is that the ECU and TCU aren’t communicating properly and when accelerating the torque converter isn’t locking.
