The automatic transmission on my 2019 Chevrolet Tahoe has failed prematurely at approximately 88,000 miles. The dealership confirmed internal transmission damage, specifically that Solenoid #3 in the valve body is sticking and not engaging, which requires a complete transmission replacement. Their written inspection states: “Possible internal damage in transmission. Solenoid 3 in valve body is not engaging.” The component is available for inspection upon request. Safety Risk: This malfunction created several dangerous situations. The vehicle hesitated, struggled to shift into gear, and at times moved forward while in reverse. These symptoms could cause loss of control, delayed acceleration when entering traffic, or unexpected movement putting myself and others at risk. Diagnosis Confirmation: Yes. The problem has been fully inspected, reproduced, and confirmed by an authorized Chevrolet dealership service center. They provided a written estimate of $8,669.59 for a complete transmission replacement. Inspection by Others: The transmission has been inspected by the dealership where the vehicle was purchased. No independent mechanic, police, or insurance representative has inspected it yet, but the dealership’s findings are available. Warning Lamps or Symptoms: Prior to the failure, I experienced hesitation, difficulty engaging gears, harsh shifting, and the vehicle lunging forward while in reverse. Shortly after these symptoms appeared, both the check engine light and tire pressure light came on. Additional Context: GM has released multiple Technical Service Bulletins (TSBs), including 19-NA-153 and 21-NA-199, addressing known issues with their 8-speed transmissions such as harsh shifting, slipping, and valve body/solenoid problems. This suggests a broader pattern of defects. GM and the dealership offered only 10% goodwill assistance, leaving almost the entire repair cost to the consumer, despite this being an internal mechanical defect with normal personal use.

Also I purchased Every warranty there was to buy when I purchased this vehicle and the dealership failed to acknowledge any one of them. So lucky I had another warranty company to bag me up and they are the ones paying this 4to 5,000 dollars repair. I’ve also had to service the Trailer brake system several times.. NEVER used it since I’ve had the vehicle.. until I asked them to just disconnect it because it wouldn’t stop.

But I reached out 1st since I seen where there is a recall but it’s not saying my year of vehicle. Please help. Also. I’m still receiving my oil changes from the dealership. And I get them on a regular. NOTE: The shop that has my vehicle is Not the one listed on the document. But this is what the diagnostic read. And this is what’s being done to my vehicle.

Driving on the interstate when all the sudden there was no power to drive train, the rpm gauge red lined. I put gear shift to neutral and rpm gauge came down, at this time no check engine light. Coasted to exit and parked. Got out and look around Tahoe for damage none found, looked under hood and no damage or fluid anywhere, none found. Got back in Tahoe and shifted into drive. I drove on 2-line highway to nearby town; 25 mph is all it would go. There was not a chevy dealer in town, stop at a Ford dealership and they sent me to an independent shop. Check engine light came on as I drove to independent dealer. Independent dealer checked for codes found transmission he checked fluid level it was full, but fluid smelled burnt and had metal shavings. He pulled it into shop and dropped fluid pan, to visually verify transmission parts were bad. He had to install a new gm transmission.
