2021 Silverado Transmission Recall / Service Bulletin
What happened with the 2019-2021 Silverado transmission
GM issued Technical Service Bulletin (TSB) 19-NA-355 and subsequent updates for Silverado 1500 and Sierra 1500 trucks equipped with the 8-speed 8L90 and 10-speed 10L80/L90 transmissions. Owners reported shudder between 15-50 mph, harsh gear changes, and slip-flare during upshifts.
GM's remedies included: transmission fluid replacement with updated Dexron HP fluid, transmission control module (TCM) software updates, and in severe cases, torque converter replacement ($1,500-$2,500).
Extended coverage: GM extended powertrain warranty coverage to 7 years/100,000 miles for a subset of affected VINs. If your 2019-2021 Silverado has transmission shudder, contact your dealer and check NHTSA.gov for open recalls on your VIN before paying for repairs.
The 2.7L EcoTec3 Turbo Engine - What to Know
The 2.7L turbocharged 4-cylinder became the standard engine on Silverado 1500 in 2019. It produces more torque than the older 4.3L V6 but has a different failure profile than the naturally aspirated V8.
Oil consumption
Some 2019-2022 2.7L engines consume 1 quart per 1,500-2,000 miles. GM issued TSB and extended oil consumption coverage. Monitor oil level frequently.
Repair cost: $0–$3,000 (piston rings if severe)
Carbon buildup (intake valves)
Direct injection without port injection causes carbon deposits on intake valves. Requires walnut blasting every 60,000-80,000 miles.
Repair cost: $400–$900 per cleaning
Turbocharger failure
Turbocharger bearing and wastegate failures reported above 80,000 miles on some units. Covered under extended warranty powertrain plans.
Repair cost: $1,200–$2,800
Intercooler / boost issues
Intercooler condensation and boost control sensor faults. Typically a sensor or solenoid replacement.
Repair cost: $200–$600
