Chevrolet Silverado 1500 (T1XX) Buyer's Guide
5.3L V8 and 10-Speed
The T1XX Silverado (2019-2024) brought a fully redesigned interior, the Multi-Flex tailgate, and the 10-speed automatic across most powertrains. It's the perennial #2 in full-size truck sales behind the F-150.
Engine choices: The 5.3L V8 with Dynamic Fuel Management (DFM) is the volume leader — it can shut off any combination of cylinders down to one. The 6.2L V8 in higher trims makes 420 hp. The 3.0L Duramax turbodiesel inline-six is the fuel economy champion at 30+ MPG highway. The 2.7L turbo four is the base engine and adequate for light duty.
What to look for: DFM-related lifter failure is the top concern on 5.3L and 6.2L engines. The 10-speed (10L80/10L90) has been more reliable than Ford's 10R80 but still worth a thorough test drive. The 8-speed (8L90) on earlier 2019 models had known torque converter shudder.
About the T1XX
The 2019-present Chevrolet Silverado 1500 is the T1XX generation, larger and lighter than its predecessor with a mix of aluminum and high-strength steel in the body. The powertrain range is the broadest in the model's history: a 4.3-liter V6, a 2.7-liter turbocharged four-cylinder, 5.3 and 6.2-liter V8s, and a 3.0-liter Duramax inline-six diesel. Transmissions are eight- and ten-speed automatics. Rear-wheel drive is standard with four-wheel drive optional, and a Trail Boss off-road package sits alongside the ZR2 introduced later in the run.
The larger body increased bed volume and cab space, and the available multi-function tailgate added practical versatility. The 3.0-liter Duramax is the standout powertrain for efficiency and refinement. A significant interior redesign for 2022 addressed the widespread criticism that the launch interior was well behind the competition.
For used buyers, the interior update is the most important dividing line in this generation, and 2022 and later trucks are considerably more pleasant inside. Dynamic Fuel Management, the successor to Active Fuel Management, continues to be associated with lifter failure on the V8s, and the repair remains expensive. The 3.0-liter diesel had early issues with certain components but has a good record overall. Confirming which recalls apply to a specific truck is worthwhile given the number issued across this run.

Frequently asked questions
Is the Duramax diesel worth it?
If you tow regularly or drive long highway miles, yes — 30+ MPG and 900+ mile range. For city/light use, the higher upfront cost and DEF system maintenance aren't worth it.
Should I worry about DFM lifter failure?
Failure rate is low on stock trucks (estimated 2-5%) but catastrophic when it happens. Many owners install an AFM/DFM disabler ($200) as preventative insurance.
5.3L vs 6.2L?
The 6.2L is noticeably quicker and smoother but requires premium fuel and has the same DFM risk. The 5.3L is the sensible choice — 355 hp is plenty for most buyers.
