Does the 2020 -2022 Chevrolet Silverado torque converter have a high failure rate? According to multiple owners, the answer is yes. Here are the problems, what Silverado owners are finding out about the problem, and what you need to know.
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.

I have two company trucks…
I have two company trucks with the 2.7 engine and 8 speed transmission. Just had a transmission replaced on the one with 103k miles. The other truck with 56k is having issues with the transmission as well. For both trucks the dealer won't even try to diagnose the issue. Had to go to a national transmission shop to get service.
I just bought 2020 trail…
I just bought 2020 trail boss and have the dreaded shutter.. previous owner stated had not been serviced to his knowledge…. 155,000.00 miles… having fluid changed now… see what happens!!!
Buy the older truck with 4…
Buy the older truck with 4 speed trans. Mine lasted 220k miles with no torque converter issues. Failed by loosing reverse. Rebuilt it and have so far put on 30k.
Bought a 2015 Silverado LTZ…
Bought a 2015 Silverado LTZ in 2017 with 10000 miles still under warranty. Do not recall if the transmission clunked from when I bought it or within a year or so. It only clunked occasionally asI went up on my moderately steep hill and would stop to back in my garage. Just one loud clunk. I thought it was just the engine dropping from 8 cyl to 4 cyl. The truck started shuddering almost always as I came to stop at the crest of an overpass exit. I would stop to make a right merge and feel a slight shudder. It almost felt like my wheels were slipping on oil. I would also experience this regularly on certain left turn after a stop. In October of 2024 on a 700 mile trip, stopped for gas and started feeling a faint shudder, like mud on a tire or ruts on the road. It would happen for 10 miles or so then disappear only to return after 30 milesor so. Made it to my destination but would only feel the shuddering when driving above 50 MPH. I was nervous on the return trip. Slowly the shuddering worsened. I delayed my return one day from Sunday to Monday in case the transmission failed. I made it home. The next day I called my local Chevrolet garage. As soon as I started the truck and put it in drive, something was worse, it was slipping on almost every stop. I had to stop by the bank and I as put it in gear to leave it hesitated and hard clunk into reverse. I limped to the Chevrolet dealer garage. The whole 15 mile trip was just a lot of shuddering. As I turned into the garage the transmission must have started to shear, for a minute the truck just revved but would not move, it clunked into a high gear and rolled into a parking spot barely responding to the gas pedal. They called me with a burnt out torque converter, some of teeth were sheared off. A rebuilt OEM with 3 year warranty was $10000.00 since I was way out of warranty and my extended warranty ran out. I thought it was going to be around $4500.00. I wasn't going to put in the same transmission that failed. My son in law is a a mechanic, used to work at a dealership. He advised a Jasper rebuilt transmission. They had a rebuilt transmission for $7000.00, 3 year warranty. It could break down any where and any shop could repair, replace. My truck had 167K miles, only a few problems, air conditioning and rear axle seals which were under extended warranty. I did research, did not know there were recommended transmission fluid change, the torque converter is a pos, the transmission cooler doesn't kick in until temperature is 190 plus, the AFM wreaks havoc on lifters and makes your transmission hunt for gears while cylinders are shutting on and off. I did install a device which keeps the truck in V8, fuel economy was reduced by about 30 to 50 miles per tank, almost zero if I drive nice. I am also installing a by pass to reduce transmission temperature so it goes the cooler and going to change the fluid at about 50k.
So far no problems with rebuilt Jasper, still holding my breath though, I have 173300 mile now. Just a bit of info, prior the Chevy I had a 2002 Tacoma, I drove it until 2017, 230K or 260K miles, I forget. I got rof the Tacoma because of the transmission, it would not go into gear occasionally. A few times it just revved on the road, no power. It started getting worse. If the Chevrolet had gone to 200k miles or so, I wouldn't have complained.
The reason is that GM went…
The reason is that GM went to a light weight material on their torque converters to make them lighter for better fuel economy and to make them cheaper. The problem is the lighter weight converters can't handle the torque and they go bad. The bigger issue is that GM knows this is happening and refuse to upgrade the converters so when you buy OEM Parts they are the same parts with the same problem.
I had the same shudder…
I had the same shudder problem so I rebuilt the transmission with a billet torque converter and shift kit problem solved
