What is the recall on the Chevy transmission?

Chevrolet has issued a recall for certain transmission models due to a potential issue that could lead to the transmission slipping or losing power. This recall affects a significant number of Chevy vehicles, and it's important for owners to be aware of the details and take the necessary steps to address the problem.

Overview of the Chevy Transmission Recall

The Chevy transmission recall involves several models and model years, including the Silverado, Tahoe, Suburban, and Yukon. The specific transmission models affected are the 6L80 and 6L90 six-speed automatic transmissions, which were used in these vehicles between 2007 and 2019. The issue with these transmissions can cause the vehicle to lose power or experience unexpected shifting, potentially leading to a loss of control and increased risk of an accident.

These problems can pose a significant safety risk to drivers and passengers, which is why Chevrolet has taken action to address the issue.

How do I know if my transmission has been recalled?

The National Highway Transportation Administration has an individual vehicle identification number (VIN) look up tool. Go to nhtsa.gov/recalls to see if your vehicle has an open recall. Many of the vehicle manufacturers also offer tools to look up if a vehicle has a recall.

What is the GM recall on transmissions?

GM has issued multiple recalls for vehicles with 10-speed transmissions, including a large recall for over 460,000 diesel trucks and SUVs due to a potential rear-wheel lockup caused by a worn valve in the transmission's hydraulic control system. Additionally, a separate recall covers over 90,000 cars and trucks where a transmission control valve issue could cause harsh shifting or, in rare cases, a brief front or rear wheel lockup. The initial fix involves installing new software to detect excessive wear, while more extensive repairs like valve body replacement may be performed if a vehicle's VIN is affected. 
For diesel trucks and SUVs (2020-2022)

• Issue: A worn valve in the transmission's hydraulic control system can cause the rear wheels to suddenly lock up, potentially leading to a loss of control, especially while towing or at highway speeds. 
• Recalled vehicles:
  • 2021 Cadillac Escalade 
  • 2020-2022 Chevrolet Silverado 1500, 2500, 3500 
  • 2021 Chevrolet Suburban 
  • 2021 Chevrolet Tahoe 
  • 2020-2022 GMC Sierra 1500, 2500, 3500 
  • 2021 GMC Yukon, Yukon XL 
• Fix: Install new transmission control module software that monitors valve performance and limits the transmission to fifth gear to prevent lock-up if excessive wear is detected. If a vehicle's VIN is affected, a dealer may also need to replace the transmission's valve body. 

For 10-speed 1500, Camaro, CT4, and CT5 models

• Issue: A transmission control valve can wear excessively, causing pressure loss and leading to harsh shifting or, in rare cases, wheel lock-up. 
• Recalled vehicles:
  • 2020-2021 Cadillac CT4 
  • 2020-2021 Cadillac CT5 
  • 2019-2020 Cadillac CT6 
  • 2020-2022 Chevrolet Camaro 
• Fix: Install new transmission control module software to detect and prevent wheel lock-up. 

What to do

• Check your VIN: Contact a GM dealership or use the official GM recall website to check if your vehicle is affected by any of these recalls. 
• Schedule service: If your vehicle is affected, schedule a service appointment to get the recall repairs completed. The initial software update is often the first step. 
• Wait for parts: Be aware that depending on the specific recall, dealers may need to order parts and your vehicle might be held until repairs can be completed.
