2024 Chevrolet Silverado 2500: harsh or hard shifting

Filed Jul 23, 2026 · Engine, Transmission · CA

First started around 4 to 6000 miles, felt a shuttering between 50 and 65 mph. Shattering lasted from 10 to maybe 30 seconds let off the fuel and reapplied still there on one or two occasions. RPMs were approximately 2000 RPM shattering stopped in our PMs went down to 1500. This is occurred many times taken to a dealership always get same result, no problem found. Problem always occurs just after a transmission shift which I can tell by RPM. When I apply gas shuttering sometimes increases not always. Also noticed that sometimes shifting on a flat surface 65 miles an hour engine will speed up to almost 2000 RPM and when it goes to shift back, I get a clunk or sometimes a shutter normal cruising is about 1500 RPM at 65 mile an hour. I didn’t notice towing an empty trailer about 2600 pounds shattering seemed worse. With no Trailer I sometimes get erratic shifting where RPM goes 1500 to 2000 to 2500 and then back down again then back up again then it can shift all the way back to 1500 RPM still maintaining 65 mph. Also another problem may be connected to transmission, but I have pulled out into traffic pushed on the pedal and it feels like the truck has no power push on the pedal a little bit more still no power and all of a sudden it’s like everything kicks in RPMs, increase rapidly and truck accelerates extremely fast, throwing things off the dash moving things on the floorboard. Sometimes I see that a downshift occurs and RPMs increase other times I see RPM staying right at the 2000 mark and it still occurs almost got rear ended a couple of times. Check engine light has been on one dealership said they pulled over 40 codes. Still they all claim can’t duplicate problem. Yes I agree it is random but with me watching telemeter and County shift points biggest problem area is fourth gear fifth gear and sixth gear.

While driving the vehicle, the vehicle jolted and made a clunk noise. The check engine light came on accompanied by a message on the Dash stating "Reduce acceleration, Drive with Care". The vehicle went into "limp mode", and appeared to be engaged in a single gear. The vehicle was traveling at approximately 30 mph when the transmission malfunctioned. The vehicle was taken to my local Chevy dealer, where they scanned the vehicle and determined that the Valve Body was the issue, based on the scan result. The vehicle is a 2024 Chevy Silverado 2500HD (Gas). It has 29k miles on it. The vehicle was purchased as a "certified Pre-owned" (lease return). Within 20 miles of being driven from the dealer after purchase, I experienced a jolt & clunk. The failure occured 42 miles later.

Transmission has locked up briefly during decelerations, has been making grinding noises, has high transmission fluid temperatures, hard shifts during acceleration and deceleration, and has slipped during acceleration.

Owner from brand new (16 miles) multiple complaints through ownership of harsh shifting, jerky throttle on and off, excessive engine braking, and have been stuck on the side of the road 3x due to the same situation. Never was a code thrown so I was continuously told there’s “nothing wrong.” On [XXX] I was driving [XXX] out of Denver making the climb towards [XXX] to home. As I had my cruise control set at 65, out of nowhere my truck locked up what seemed to be the rear wheels completely, causing my rear end to sway violently. I immediately slowed down and pulled over with no indications or lights being illuminated on my dash. I turned the truck off and let it sit for 10 minutes and restarted it. Having no issues I signaled back onto [XXX] and the truck accelerated to nearly 65 with no issues. As I hit 62 on the dash it again locked up the rear tires. I again pulled over, this time questioning what could be causing this, knowing the first time indeed was what happened. I put my truck into park, and still had no warning lights or check engine light. I then put my truck into neutral and then clicked the auto button thinking maybe something with the rear end is locking my brakes up. Upon doing so I again entered the roadway, big mistake on my part as this time upon reaching 60+mph all 4 tires simultaneously locked up. How I didn’t roll, I have no idea. Easily the scariest set of events I’ve ever faced while driving and that’s considering all of the insane drivers on our roadways today. I literally lodged a complaint with Chevrolet the same day I bought this truck before ever even leaving the dealers lot, and have had zero communication from them other than myself reaching out. They have ignored the problem literally from day one and it easily could’ve cost me or someone else their life. I’m appalled that to date they are still selling these trucks, replacing the valve bodies with the exact same faulty ones, and allowed to put others in danger constantly.

I purchased a 2024 Chevrolet 2500 HD Crew Cab High Country and reported harsh shifting after 3 months 3,000 miles and told that nothing was wrong. Brought truck back in in February 2025 with 12,000 miles due to erratic shifting and loud whining noise. After 4 days in the shop they agreed that there was a problem but didn't know what the problem was. One week ago on Sunday 3/23/25 While driving the engine would rev up for acceleration but didn't speed up. Got to my son's house two miles away. I went leave 20 min. later and the transmission died completely. It would not go forward or reverse.

This vehicle has a severe transmission shift issue that will likely cause an accident at some point. This vehicle has an Allison 10 speed transmission and began shifting extremely hard or violently from 7th to 8th gear in November of 2023. This problem began when pulling a travel trailer that is weight rated well below the capacity of this truck. This hard shift causes vehicle occupants to lunge during the event and it is feared that a catastrophic failure will occur, resulting in a vehicle accident. The vehicle was taken to the dealership where purchased as it is still under manufacturer’s warranty, and in March of 2024 the dealership performed a software update and transmission “re-learn” which solved the issue until the truck was used to pull a travel trailer again. The issue returned in November of 2024. The truck was returned to the dealership for follow up but the dealership has not taken any further action to resolve the problem at this time. There is a service bulletin (N242467600) issued from GM that seems related to this vehicle but I’ve received no notification that this vehicle is eligible for transmission replacement under this service bulletin. This issue will likely result in a personal injury or vehicle accident at some point.
