Yes—some 2015 Silverado pickups have reported transmission problems, especially with the six-speed automatic (6L80/6L90). Not every truck is affected, but complaints include shuddering, rough shifting, slipping, and delayed engagement.
What owners have reported
Across owner forums, consumer complaints, and early-2010s recall data, a pattern emerges around certain transmission behaviors and combinations.
Common symptoms by configuration
- Transmission shudder or judder at moderate speeds, often during light throttle
- Rough or delayed upshifts or downshifts between gears
- Slipping out of gear or failure to stay engaged in drive
- Torque converter issues, including lock-up concerns or heating symptoms
- Harsh downshifts or surges when accelerating
Note: Symptoms can vary by engine (for example, V6 versus V8) and driving conditions. Some issues trigger diagnostic codes that lead to software updates or hardware replacements under warranty.
Official responses and remedies
GM has issued service bulletins and, in some cases, field actions addressing 2014–2015 Silverado transmissions. The emphasis has typically been on software updates and, when needed, hardware repairs under warranty.
- Transmission control module (TCM) software updates to improve shifting and torque converter operation
- Valve body inspection or replacement where sticking or clogging is suspected
- Torque converter replacement if shudder or limp-like behavior persists after software updates
- Full transmission replacement in rare cases where failures remain after other remedies
- Recalls or service actions may apply; verify your vehicle’s VIN for open recalls and service advisories
For the most accurate, VIN-specific information, owners should check recall statuses and service bulletins via the NHTSA recall database and the GM Owner Center.
How to check and address transmission concerns
If you own a 2015 Silverado and notice transmission symptoms, use a step-by-step approach to protect yourself and get a proper fix.
- Check for recalls and service advisories using your VIN: consult the NHTSA recall database and the GM Owner Center.
- Document symptoms with dates, mileage, and operating conditions (speed, throttle position, ambient temperature).
- Visit a GM-certified technician and request a diagnostic run; start with any available software updates as a first step.
- If symptoms persist, have the technician inspect the transmission hardware (TCM, valve body, and torque converter) and discuss warranty coverage or goodwill options.
- Keep all service records and be aware of your rights under warranty, extended coverage, or lemon-law provisions in your jurisdiction.
Timely diagnosis and adherence to recommended service actions can mitigate long-term damage and improve the odds of a satisfactory resolution through warranty or service programs.
Summary
In short, the 2015 Chevrolet Silverado has a subset of vehicles that experienced transmission problems, notably with the 6L80/6L90 automatic transmissions. While not universal, these issues have been reported by owners and have prompted GM service bulletins and, in some cases, recalls. If you own a 2015 Silverado, stay informed about VIN-specific recalls, monitor for symptoms such as shuddering or delayed shifts, and work with a GM-certified dealer to determine whether software updates or hardware repairs are warranted. Staying proactive and documenting symptoms improves the chance of a prompt, appropriate repair.
What year Silverado transmission to avoid?
2011 and 2014 Models
Both the 2011 and 2014 model years had several issues, but the 2014 Chevy Silverado 1500 is the worst model year. Transmission failures, engine problems, cooling issues, stalling, and a noisy engine plague both model years, but the 2014 earned far more complaints from owners.
