The transmission in this truck has been an issue since it had 50k miles on it. It doesn-??t shift correctly or smooth at all. It shifts hard, slow to engage, studders, jerks, pops without any load. This is my second 2021 Chevrolet Silverado 1500 with same issue except it needed transmission replaced and didn-??t know when they-??d get another transmission in as they-??re on backorder and these are work truck and can-??t be down long - dealer said this is a common issue with these trucks - so I got rid of that one. If the dealers know this is a common issues and attorneys are sending letter for class action lawsuit against GM this should tell you something- recall them! No lights have ever come on with any warning on either truck.

- Northlake , TX, USA

Open recall with no remedy. Called GM and they cannot give me any timeframe as far as when a fix will be available. GM has proposed changing the software to limit the truck to fifth gear if excessive wear of the valve is detected but that is not a fix for the issue and they cannot even give a timeframe for that or what they will do to remedy the issue when there is excessive wear. The issue can cause the rear wheels to lock up while driving and is a major safety issue compounded with winter driving conditions yet GM cannot provide any information. I cannot even replace the vehicle as the vehicle cannot be sold in my state of Missouri with an open recall.

MY Windshield wipers stop working on low and high and from time to time my vehicle will not go in reverse. when it does finally go in reverse it's a very hard jerk, also when I'm driving it gets a drag an acts like it wants to stop going. It happens frequently and it has been going on for months.

- Rex, GA, USA

UNKNOWN - The truck began jerking/braking on its own while driving last week. I took it to a local transmission shop where it has sat for the past week as they said the transmission control module/tcm needs to be replaced but the part needed is on back order. This issue sounds similar to the recent transmission recall (N242454440) though our vin does not show there to be a recall on our exact vehicle. Our truck meets the specifications of the recall and having it inoperable has placed a hardship on my family. How can I get it fixed under this recall at a local GM dealer?

Transmission issues such as vibration/grinding, delayed shifting, rough shifting, clunking noises when changing gears, jerking sensations, vehicle is available for inspection. The transmission control valve may fail, causing the rear wheels to lock up. Transmission was inspected, Dealer claimed Torque converter issue and replaced that part, however, ISSUE still exists and Dealer claims that at the 2nd inspection, it was the tires giving me the rough shifting and vibration/griding I feel when driving. No warning messages, just continued vibration that turned into grinding at it continues to get worse. Issue started at 55K miles, truck currently has 60K miles, torque converter was replaced at 58K miles. The issues seems to be the same as the current GMC Diesel transmission recall.

- New Orleans, LA, USA

My truck has less than 50,000 miles on it and the transmission feels has if it's shifting hard and shuttering during the cycles of first to third. I do not see that my truck has a recall, but if there is a problem with my trucks transmission, then I need to have it looked at before the 60, 000 or 5 year warranty expires. Can I just take it to a Chevy dealership and have this inspected at NO CHARGE to me?

When you drive the truck for at least an hour then you turn it off the entire front like vibrates or shakes. It almost feels like something is still turning in the transmission but everything is turned off. This particular truck has already had the engine replaced at 14,000 miles bc it was faulty. It also has issues with tires. The radio and lights also all go off for brief time and then it comes back on. At times the drives side seat belt will lock and it pins you to the seat where you cannot move and you have to remove the seat belt. It is becoming more of an issue. I believe the transmission to be going out. Today, I wasn-??t sure if the vibration in the truck was going to stop. So I stopped driving the truck and went and got another vehicle to drive
