Does the 2020 Chevrolet Silverado 3500 have transmission problems?

Owner complaints say yes, as a model-year pattern. 14 of 28 relevant complaints filed with NHTSA about the 2020 Chevrolet Silverado 3500 concern the engine, transmission or fuel system (50%), and the largest group is filed under power train (9). For comparison, the 2021 scores 35%. On a test drive, check for shuddering, slipping, delayed or harsh shifts, or a whine at speed. This describes the model year, not any one car: a well-maintained or already-repaired example can be fine, and a clean model year can still have a bad car in it.

Manufacturers fix things mid-generation. A bad year next to a clean one is common; the fix usually arrived in between.

Other heavy-duty pickups with no elevated signal

The percentage is each model year's drivetrain complaint share. No elevated signal describes the model year, not any one car; a well-kept example of a flagged model can still be the right buy, and any of these still needs an inspection.

Which Chevrolet Silverado 3500 years are better?

Should I buy a 2020 Chevrolet Silverado 3500?

That depends on the car in front of you, not just the model year. The 2020 Chevrolet Silverado 3500 has an elevated transmission complaint pattern, so treat it as a car that needs proof: service records showing transmission work, a cold-start test drive, and an independent pre-purchase inspection focused on the transmission. A well-kept or already-repaired example can be a fine car; an unknown one is a gamble.
