My 2020 Silverado Torque Converter Was Replaced At 49K Miles Due To a Severe Shudder, Now, at 70K Miles, the Shudder Has Returned

Does the Chevrolet Silverado have transmission issues?

Yes, the Chevrolet Silverado does have transmission issues, as many owners have experienced torque converter failure. On the 2019 - 2025 Chevy Silverado and GMC Sierra Owners Facebook page, numerous posts discuss this very issue, reflecting the shared experiences. 

Jacob Parlak says, 

"I have a 2020 Silverado with the 5.3 and 8L90 transmission. At 49,000 miles, the torque converter was replaced under warranty due to a shudder when coming to a stop. Now, at 70,000 miles, the shudder has returned. I've been told there's no warranty coverage for the same issue just 21,000 miles later."

"Does this mean I'll need to replace the torque converter every 20,000 miles, or is there a permanent fix? Would a transmission drain and fill help resolve the problem? Any advice would be greatly appreciated—thank you!"

Another Chevrolet Silverado Owner says,

James Hughes says, "If it just started to do a transmission flush first...mine was doing the same, and the new fluid cleared it up. Chevy recommends a transmission service every 45,000 on these transmissions.

Joey Renteria says,

"I own a 2022 Chevrolet Silverado 2.7-liter with an 8-speed transmission. I got the call that my torque converter failed, so they are going to replace the transmission. It started doing it about 1-2 months ago. I bought it at 60,000 miles, and the problems began at around 85,000 miles."

"The tech said the transmission is about 10 days out (not including installation). Seems too soon compared to what others have said they waited. Should I not get my hopes up? Regardless, they are providing the rental."

General Motors Does Have Problems With its Automatic Transmissions on Silverado and Sierra Trucks

I have documented multiple cases of owners experiencing transmission failure. Check out my report here for more information. 

Does GM Recommend a Transmission Flush or Fluid Exchange?

One thing Silverado and Sierra owners can do to take control of their vehicle's health is to service the transmission regularly. This proactive approach could prevent potential issues and keep your truck running smoothly. 

General Motors does not typically recommend a transmission flush for Silverado and Sierra trucks as part of routine maintenance. Instead, a transmission fluid change is recommended, and the interval for that service depends on the driving conditions. 

Here's a more detailed explanation:

• Transmission Fluid Change: Chevrolet recommends changing the transmission fluid, particularly for those with automatic transmissions, every 45,000 to 60,000 miles or as specified in your owner's manual. 

Why Not A Flush?

Flushing can dislodge debris within the transmission, which could lead to further problems. 

• Severe Service: If you engage in severe service conditions, such as frequent towing or hauling heavy loads, the transmission fluid change interval may be shorter (e.g., every 45,000 miles). 
• Check your owner's manual: Always refer to your specific Silverado's owner's manual for the most accurate maintenance schedule and recommendations. 
• 10-Speed Transmission: The 2020-2022 Silverado typically features a 10-speed automatic transmission, and it's essential to use the correct type of transmission fluid (Dexron-VI ATF). 
• Fluid Type: For the 10-speed transmission, use only Dexron ® ULV transmission fluid. 

Chevrolet says,

Factors to Consider:

• Towing: If you frequently tow heavy loads, you must change the fluid more often. 
• Driving Conditions: If you drive your Silverado in harsh or off-road conditions, you should also change the fluid more frequently. 
• Transfer Case Fluid: If your Silverado has fo-r-wheel drive, the transfer case fluid may also need to be replaced at certain intervals, potentially around 45,000 miles. 
• Severe Service:
• For severe service duty (e.g., frequent towing, off-roading), the recommended interval for changing the transmission fluid and filter is every 45,000 miles. 

Conclusion:

The automatic transmission in the Chevrolet Silverado and GMC Sierra is its weak point. 

According to discussions on Reddit and other forums, there are reports of transmission issues with the 2020-2024 Chevrolet Silverado and Sierra, with users mentioning problems like torque converter failures, "blown valve bodies," and concerns about the transmission running too hot, leading to potential premature wear and tear, particularly when towing heavy loads. 

Owners should have the transmission serviced every 45,000 to 60,000 without fail. This could prevent premature torque cover and transmission failure.
