My vehicle has developed a recurring problem involving harsh/jerking transmission engagement, hesitation, shuddering and abnormal shifting. The truck can jerk when engaging or changing gears and has also experienced a hard engagement when shifting from Reverse into Drive. During normal driving, the vehicle can hesitate or feel as though it is repeatedly fluttering/shifting instead of providing smooth and predictable acceleration.  The vehicle has produced diagnostic trouble codes including P0700, U0100 and P0420.  I am concerned that this condition could create a safety hazard, particularly if the vehicle unexpectedly jerks, hesitates or fails to respond normally when accelerating or changing gears in traffic.  I am requesting that NHTSA document this complaint and review whether there is a pattern or potential safety-related defect involving transmission engagement, shifting or drivetrain control on 2021 Chevrolet Silverado vehicles.  GM has published service information concerning delayed and harsh transmission engagement on certain Silverado applications, including 2019–2021 models, which makes me concerned that my vehicle may be experiencing a related issue.   I am retaining my repair records, diagnostic information, receipts, videos and mileage/date information documenting when the problem occurs. I am willing to provide this information if requested. Please help me get my truck corrected, I love my Chevy Truck.
