TC Shudder
Took 2017 c7 A8 into Chevy dealer for TC shudder. They invoiced me for transmission flush. Thought it should be covered under powertrain warranty. Anyone know a definitive answer and recommendations on how to proceed.
Update: was charged over $400 for the transmission flush to correct TC shudder. Contacted Chevrolet Customer Care and they finally offered to reimburse me $103. Said the codes in the TSB pertained to bumper to bumper warranty and not drive train. The C7 is a 2017 with less than 20,000 miles. Any advise on how to proceed?

Triple flush on my 2016 C7 A8 was done under powertrain warranty at no cost and no questions asked. I had a copy of the TSB with me at the time of the service, think it is TSB-18-355 but am not sure. I can look it up but I am sure someone will know if that is not correct.

TSB-18-NA-355, it is supposed to be done under Powertrain Warranty at customer's request. Do not have to have proof of shudder, is done at owner's request, no questions asked. I had no problems with getting mine done at the dealership at no cost to me.

Take a copy of the TSB with you. The procedure is required to be completed as part of the Powertrain Warranty when a customer complains of the shudder. As long as your car is still within the Powertrain Warranty period it is covered.
