According to the gm bulletin that was released I believe in may of 25 my year, make and model has a known issue where the transmission control valve may stick or wear causing jerking and shifting issues and could cause a possible crash. According to the bulletin by gm the fix is to replace the valve cover on the transmission. My vehicle is currently at the Cadillac repair center for this shifting issue and it has been diagnosed to need a valve cover replacement to solve the problem.

Now I have to pay for the repair because my vin is not specifically listed yet but my year, make and model and problem and the solution is all listed . I know I’m apart of this recall please help me
ENGINE Apr 16, 2025
valve body failed and was supposedly repaired. I had the car 1 day and valve body failed again. My car has been in the shop since November 4, 2024 with no estimated time of repair because no parts are available. I was told they would replace the transmission. That has not happened yet. No parts available. My car has been disable for 6 months.
