Jerking or hard shifts on other Silverado 1500 years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2015, 2023, 2024, 2025, 2026.
What this problem usually is
This is the narrower sheet inside transmission shudder for shifts that jerk, lurch or bang. Where the wider sheet also takes in slipping and vibration, these reports are about a shift that arrives too hard: the car lunges forward, or a clunk comes through the floor as it drops into gear.
What got replaced
Owners who name the part that was replaced mention the valve body (6 reports) and the transmission (5 reports).
Recalls and investigations
2 recalls on the transmission and drivetrain cover the 2021 model year. A recall on the same system isn't always the same failure, so read the defect text.
The transmission control valve may fail and cause the rear wheels to lock up.

Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.
