2015 Chevrolet Traverse Transmission and drivetrain Problems

“Initially I had an issue with sudden heavy vibration, primarily while turning, was not recording with a fault. Per my service records attached there were several trips try a diagnose and repair the issue. The mysterious issue requiring GM engineer support outside of the local dealership technicians. Shortly after my final service for the vibration issue I reported abnormal shifting during acceleration and was advised that the shifting trained to the driver.

“My wife was driving our 2015 Chevrolet Traverse 2lt in a construction zone at the speed limit. The vehicle abruptly shook side to side several times, then shut off engine power abruptly and lurched forward and back 5 times hard enough to throw her into the seat belt.
