Power Train problem #1

My 2021 Chevrolet Express van with an 8l90 transmission has failed after only 80k miles, willing to have it inspected. Check engine codes show p0700 and p2714 on 02/08/25. No prior warning lamps. This product has put my safety at risk due to overheating and making the vehicle go into limp mode while on public roadways. The product is known to fail for trucks alike with the same transmission but has yet to be reported for the Chevrolet Express. Has only been confirmed via obdii scanner from parts shop.

Power Train problem #2

When I come to stop in traffic the drivetrain suddenly jolts and pushes the vehicle forward potentially pushing me into the car or traffic in front of me unless I put it in neutral or press hard on the brakes approaching the stoplight. Happens everyday.
