Harsh transmission downshift when coming to a stop
The vehicle is actually a 2012 S4 but the model is not listed same engine transmission package nonetheless. The symptom is when you come to a stop The vehicle will downshift hard and it feels like it's somebody hit you from the rear end. I scan the vehicle and found no trouble codes and engine or the transmission. I'm not 100% sure of what pids to look at or what I'm looking for at this point any suggestions would be appreciated Thanks.
Its probably in the s tronics. Or the low side of the dual clutch is going bad.
