Being that the TCM is mounted right under the ECM in the cowl on the B6, the communication wires go from one, right into the other. On an Allroad, the TCM is mounted under the seat and the communication wires go from there to the speedo and then to the ECM. The shop that is working on the wiring told me that being that the Allroad TCM is mounted farther away, the speed or wave length of the communication that is sent is different and will not communicate with the 2.7t ECM. I'm in no means a wiring expert but seemed to make sence, just not what I wanted to hear. I'm told the only way to cure this issue is to swap a manual transmission. Seeing if anyone has any ideas or am I stuck swapping the trans also? A 6 speed would obviously be preferred, just not quite in the cards right now. Any ideas would be greatfully helpful. Thank you.
Sounds like a load of BS to me, I just don't think they feel like figuring out the wiring.
