Transmission shudder 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: 2024, 2025, 2026.
What this problem usually is
This is the biggest drivetrain group on the site: a transmission that shudders, slips, hesitates or bangs into gear. It's the everyday version of transmission trouble, where the car still drives but doesn't drive right, and it has three narrower sheets of its own for jerking, hesitation and slipping.
What got replaced
Owners who name the part that was replaced mention the torque converter (10 reports), the valve body (10 reports) and the transmission (8 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.

Is this a known problem?
The manufacturer has sent NHTSA 21 service bulletins or notices for the 2021 Chevrolet Silverado 1500 that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. 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.
Certain vehicles listed above, may have a condition where the transmission control valve has worn, resulting in a gradual loss of pressure within the valve.
This service bulletin advises the technician to check if the transmission cooler lines are twisted to correct customer concerns of Harsh Shift, Shudder, Surge, Stall, Transmission Overheating and/or High Transmission Fluid Temperature.
This service bulletin helps diagnose/reduce possible CCND issues on Transfer Cases - Service 4WD on DIC, Intermittent Failures, Noise Concerns, Driveline/Steering Vibration/Shudder, Intermittent DTCs/MIL Illuminated, Engagement/Disengagement/Ratcheting ...
This service bulletin provides information on Transmission Adaptive Functions and Correcting Low Mileage Harsh Shifts, Slips, or Flares.

Should you keep driving it?
This page can't tell you that. 1 of 95 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
