Complaint Summary
POWER TRAIN
Owner Narrative
The transmission has all the symptoms of a broken wave plate and/or torque convertor as reported in the first generation T75 transmission service bulletin. This started occurring at 120K. I know the service bulletin was for the 2007-2009 models but the 2012 had the same exact transmission and waveplate. The car feels like it's going to shudder out and die on the highway.
