What transmission does the 2027 Silverado HD use?
The 2027 Silverado HD uses a 10-speed automatic transmission. Diesel-equipped trucks use the Allison 10-speed, which also provides diesel exhaust braking to reduce brake stress on long downhill grades.
Does the diesel have a longer warranty than the gas engine?
Yes. The diesel powertrain is covered for 5 years or 100,000 miles. The gas powertrain is covered for 5 years or 60,000 miles. Both are backed by the standard 3-year/36,000-mile bumper-to-bumper warranty.
Towing and Payload
How much can the 2027 Silverado HD tow?
Up to 38,000 lbs when properly equipped with the Duramax 8.3L diesel. Towing capacity with the gas V8 reaches up to 19,000 lbs. Actual tow ratings vary by configuration, so confirm the specific setup that meets your needs.
What is the max payload capacity?
6,990 lbs is the maximum available payload with the gas V8. The diesel-equipped truck reaches up to 6,170 lbs of payload. These figures make the 2027 Silverado HD one of the most capable HD trucks available.
What towing technology comes standard?
Standard towing technology includes Adaptive Cruise Control, diesel exhaust braking (on diesel models), and up to 14 available camera views for hitching, trailer monitoring, lane changes, and reversing. Available features include Trailer Side Blind Zone Alert and an in-vehicle trailering app. The Allison 10-speed transmission also includes grade-braking strategies to protect the brakes under load.

Trims and Configurations
How many trim levels does the 2027 Silverado HD offer?
Six trims are available: WT, Custom, LT, LTZ, ZR2, and High Country. The WT is the work-focused entry point. High Country sits at the top with a focus on premium comfort. ZR2 is the off-road-focused trim.
What is the difference between the 2500 HD and 3500 HD?
Both the Silverado 2500 HD and Silverado 3500 HD are part of the 2027 Silverado HD lineup. The 3500 HD is built for heavier commercial and gooseneck/fifth-wheel towing. Specific configuration differences between the two are best confirmed with the team at ASA Auto Plaza of Austin, who can match you to the right setup for your work.
What does the ZR2 trim add for off-road use?
The ZR2 brings Multimatic DSSV dampers, a rear e-locker, 35-inch MT tires, aluminum skid plates, and a 1.5-inch factory lift. It is also the first HD truck to offer Terrain Mode, which is unlocked by the combination of electric power steering and the eBoost braking system. Terrain Mode lets you dial in control for dirt, sand, and rock surfaces.
Is Trail Boss available on the 2027 Silverado HD?
Yes. Trail Boss is an off-road package available on the 2027 Silverado HD. It includes a Z71 suspension with mono-tube shocks, an Autotrac 2-speed transfer case, and BFGoodrich All-Terrain tires on 20-inch wheels. For 2027, Trail Boss is available on the Custom trim for the first time.

Technology and Features
What is the infotainment setup on the 2027 Silverado HD?
A 13.4-inch touchscreen is the centerpiece, paired with a 12.3-inch Driver Information Center. Google Gemini AI assistant is built in, and Google Built-In is available. OnStar Basics comes standard for 8 years and includes remote commands, Automatic Crash Response, built-in voice assistance, and real-time navigation.
Does the 2027 Silverado HD have a camera system for trailering?
Yes. The 2027 Silverado HD supports up to 14 available camera views. Those views cover hitching, lane changes, reversing, and trailer monitoring. For anyone who regularly backs into tight spots in Austin or on a jobsite, this system significantly reduces the guesswork.
What is the eBoost electronic braking system?
eBoost is a first-in-class electronic brake boost system for HD trucks. It uses advanced technology to deliver smoother, faster brake response and improved stopping consistency, including under load on long downhill grades. The front rotors measure 14.6 inches with four-piston calipers.
What is first-in-class electric power steering, and why does it matter?
Electric power steering replaces the traditional hydraulic system. For the 2027 Silverado HD, Chevrolet calls it a first-in-class feature for the HD segment. It provides more precise, responsive steering with less kickback on rough terrain, quieter operation, and reduced maintenance compared to hydraulic systems. It also enables Terrain Mode on the ZR2.
Does the gas V8 get an oil level sensor readout?
Yes. The enhanced 6.6L gas V8 now includes a standard oil level sensor with a Driver Information Center readout, so you can check oil level without popping the hood.
Safety
What safety features come standard on every 2027 Silverado HD?
Every 2027 Silverado HD includes Automatic Emergency Braking, Front Pedestrian Braking, Lane Keep Assist with Lane Departure Warning, Forward Collision Alert, Following Distance Indicator, IntelliBeam automatic high-beam assist, and Adaptive Cruise Control. These are standard across all trims from WT through High Country.
Does the eBoost system count as a safety feature?
It contributes directly to safety. The eBoost electronic braking system provides more predictable brake feel and improved stopping power, especially when towing heavy loads downhill. Pairing it with diesel exhaust braking on diesel-equipped trucks gives drivers multiple layers of braking control.
