Power Train Problems of Chevrolet Silverado 2500 - part 2

First issue was around April-may 2025 when my engine started knocking and burning fuel. Warning light came on and it went right in to the dealer where I have all my maintenance done. They determined that it due to (2) faulty fuel injectors and I had them replaced at that time. In December of 2025 my engine started doing the same thing as before with the knocking and burning fuel and reduced speeds when on the highway so again it went into the dealer. It has since been in there and first was told it was the fuel injector again. They priced out the one was bad and I asked them to replace the remaining 6 fuel injectors so I didn't have this issue again in the near future. They did and the vehicle had the same issues going on. During the next inspection it was determined that the engine needed new rocker arms. These were replaced but this also did not solve the problem and the vehicle would not pass the regeneration on the engine. During the next inspection it was determined that we needed to replace a cylinder and one of the valves. After this was complete they were still having issues and then I was told that the piston was bad and there are (2) bad valves so I need an entire engine replacement. My truck only has 130,000 miles and has been in the shop for almost 2 months last year from engine issues and it has had all maintenance completed at he same dealership with records.

While driving, the 10l1000 transmission in the truck attempted to shift from 6th gear to 7th gear. The transmission locked up causing a violent "buck" from the rear end of the truck. The road was icy and could have caused the truck to lose control due to the lock up of the rear wheels. After getting the truck to a repair shop, valve body was deemed the cause of the failure. A complete transmission replacement is needed. Had I lost control of the vehicle due to the lock up, my family and other motorists would have been put at risk of severe injury or worse. No warning lights were illuminated prior to failure.

I purchased my 2025 Chevrolet Silverado 2500hd new from wilsonville Chevrolet in oregon. Since owning the vehicle, I have experienced a noticeable shutter/vibration at highway speeds, consistently between 70–75 mph, whether towing or not. The shutter feels like it is coming from the transmission or driveline, and it occurs on multiple road types and conditions. I reported this issue to wilsonville Chevrolet, but they told me they “could not duplicate” the problem and offered no repair. I then took the truck to power Chevrolet in corvallis, who stated the tires were out of balance and replaced them. This did not resolve the issue, and the shutter at highway speed remains exactly the same. I also contacted gm directly, but was redirected back to the dealership, resulting in no progress. At this point the issue has been reported multiple times, yet no root cause or repair has been provided. I am essentially being sent in circles without a solution. There appears to be a growing history of transmission-related issues with newer Chevrolet hd trucks equipped with the allison 10-speed transmission, and this symptom seems consistent with those reports. A shutter at sustained highway speeds raises a significant safety concern, as a transmission failure at 70+ mph could lead to loss of control or power. In addition to the shutter, I have repeatedly noticed a strong “burning brake pad” smell coming from the rear of the truck. This happens randomly and has also been reported to the dealership, but no cause has been identified. I am unsure whether this is related to the transmission issue, but combined, these symptoms suggest a potential mechanical defect. Given the safety implications and the lack of resolution from authorized dealerships, I am requesting NHTSA’s assistance in investigating this issue.

The vehicle developed a extremely hard down shift and then a check engine light came on. The vehicle went into limp mode, took the vehicle to local diesel mechanic and I was informed that the transmission was bad and had to be replaced, while replacing the transmission I was also told the transfer case was making noise and needed to be replaced. This happened in November of 2025 and the parts are not available. This happened while I was towing our trailer across a bridge when the traffic came to a sudden stop, once traffic started moving we could not get up to speed thus causing a traffic hazard. Yes the repair shop was able to recreate the issue there were no warnings prior to the failure. I know gm has had issues with transmissions in newer models, I did not know that there was a process like this prior to getting my vehicle repaired and I needed it repaired as soon as possible. That is why I went to and independant repair facility.

The vehicle experienced a sudden and complete transmission failure at approximately 77,800 miles. There was no prior abuse or modification. The failure resulted in loss of normal drivability and required full transmission replacement. The transmission was replaced with a remanufactured unit due to catastrophic internal failure. Repair costs were approximately $7,000. I am aware of similar gm transmission issues and recalls affecting comparable model years and components. Although my VIN is not currently listed under a recall, the failure appears consistent with known gm transmission defect patterns. The failure occurred while the vehicle was in the middle of an intersection in heavy traffic, resulting in sudden loss of vehicle functionality. A child passenger was onboard at the time. The incident created a significant safety hazard due to loss of drivability in an active traffic environment.

10l1000 transmission, began having problems with delays and harsh gear engagement. Flare shifting and shuddering. Finally starting having transmission overheating issues while towing. I had to make several unsafe stops with a trailer to wait for the transmission to cool down again before continuing to get it home. Saw trans temps up to 240°f on flat land with 40° outside temps. I could smell the hot transmission fluid inside the truck. When I went to check the fluid level of the transmission, the fluid was full but had a large amount of glitter like metallic flakes. The fluid was very dark brown in color and smelled terribly burnt. The last recall I took in to the dealer for was about the transmissions possibility of failing, locking up, along with the rear wheels at any speed. I have young children that ride in this truck, that in it self was unsettling and unsafe. But then to have issues with absolutely no warning light was concerning. Ive since ordered an aftermarket built transmission to avoid repeating the same issues with a factory gm replacement. My factory warranty had also ended a few months prior to having these problems with it. Leaving me to completely foot the bill for it to be replaced. I had to pull money from my retirement early to cover costs, in fact costing me much more than just the sticker price.

I just financing this car and dealer write on dmv price of $57,057 with 63,631 miles that the tell me that was a pre contract on 9/13/24 then they then the bring the truck on 9/15/2025 with 64156 miles at the price of 61,777 on the contract I dont know what to do.

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.

I am writing to express my serious concern and frustration regarding the unresolved recall on my 2020 Chevrolet Silverado 2500 (VIN: [xxx] ). Despite multiple visits to multiple dealerships, I was repeatedly told that the necessary parts to complete the recall repair were on back order and instructed to “wait for parts. ” no interim solution or assistance was ever offered. As a result of this delay, my vehicle broke down without warning, leaving me stranded on the side of the road. This created a hazardous situation and significant disruption to my day. To make matters worse, I had to pay out of pocket to have the truck towed to a repair shop in an effort to get it operational—an expense I should never have incurred given the known recall and repeated attempts to have the issue corrected by Chevrolet. I have been a loyal Chevrolet owner and have always trusted the brand for its quality and dependability. However, this delay and lack of proactive support is causing significant inconvenience and eroding that trust. This situation is unacceptable for several reasons: 1. Safety risk and recall obligation: Chevrolet acknowledged the defect by issuing a recall, yet I have been forced to operate a vehicle that does not meet your own safety standards for months. 2. Repeated service attempts with no resolution: I followed the proper process and visited an authorized dealer multiple times, only to be turned away each time with no solution beyond “wait for parts. ” 3. Breakdown and financial loss: the vehicle failure and subsequent towing expense are a direct consequence of Chevrolet’s inability to provide timely parts or alternative accommodations.

Transmission valve body issue.

In December of 2024 safety recall n2424440-01 was applied. On the morning of Saturday August 23, 2025 while driving on a two (2) lane highway with the cruise control set to 60 mph the vehicle “shuttered” then the shifted into a lower gear locking the rear wheels bringing the vehicle to an almost complete stop in very short distance. I was able to pull off the road out of traffic. Since it was a light traffic morning, no one else was close limiting the risk to me. Had there been anyone behind me they would have been caught off guard by the sudden stop with no signal of brake lights showing. The vehicle is in “limp mode” and will not exceed 35 or 40 mph. The vehicle will shift in to park and neutral. It will not move in reverse forward. The vehicle has been transported to the nearest Chevrolet dealership for diagnostics and service.

The contact owns 2022 Chevrolet Silverado 2500. The contact stated while driving approximately 50 - 70 mph, the transmission shifted from second gear to eighth gear. No warning light was illuminated.

“shift to park” warning light appears even when vehicle is in park. Faulty solenoid in steering column.

Tramsmission valve body failed causing lack of porpulsion and inability to put the pickup in park while in traffic. After coasting to the nearest chevy dealer they cleared the codes so I could drive home and take it to my local chevy dealer ASAP. The local chevy dealer refused to inspect it until the check engine light came back. One week later the transmission violentley down shifted into 5th gear and stayed there until it was shut off it would not go into park. On the second occurances it gave codes p0700 and p0747. It was towed to the local chevy dealer who claimed to inspect on 3 ocassions but efused to give me any paper work on the results of the inspection. Beacuse they never inspected it. I took it to an indepent mechanic to replace the valve body. The 5000 miles since the valve body replacement have been uneventful. No indicators of failure were seen before the inital failure.

Sudden jerk power train and deceleration while driving and towing 5th wheel, immediate loss of power and could have been catastrophic. Gm has a known defect that requires immediate attention and investigation to affirm this is a broad national problem with the allison 10 speed 10l1000 transmission, specifically the defective transmission control valve body assembly. Do we have to wait for multiple family members to be killed or seriously injured due to this known defect? time for action and resolution. My local dealer tells me this is bigger than anyone knows. . . Why?.

While towing my travel trailer at 55 mph the truck rear tires locked up causing an alerting situation. The transmission automatically shifted out of tow/haul mode, the cel illuminated and the following message appeared on the dash "reduced acceleration condition, drive with caution". This event happened a total of 3 times within a 20 mile distance. Because it was a short burst and I was traveling on a straight section of roadway, the risk of accident was moderate. This would have been a high risk of danger if I were on a curving downhill section of roadway. The situation was confirmed by my local dealer through a diagnostic check exhibiting a p0747 and p0700 error code. There were no cels or other warnings prior to the lockup. The diagnosis was a problem with the transmission valve body. A new valve body was ordered and arrived 14 days later. After the new vb was installed the symptoms appear to be gone after driving about 50 miles.

Truck went into “reduced acceleration” or “limp mode” while pulling my camper. Took truck to kool Chevrolet in grand rapids, mi. They confirmed it is a bad valve body on the transmission. No estimated time from chevy on getting a replacement valve body. They confirmed this is a widespread known issue and could be weeks if not months. I have a family camping trip planned for the upper peninsula of michigan in mid July and they aren’t giving not giving me any indication that I could have my truck back by then.

Gm has acknowledged the problem and has issued a recall on transmissions effecting 2020 – 2022 Chevrolet Silverado 2500/3500 heavy duty trucks equipped with diesel engines manufactured between January 28, 2019 – January 11, 2022. Our truck, a 2021 Chevrolet Silverado 2500hd, was taken in to d’arcy Chevrolet in morris, IL to have recall n242454440 – momentary rear wheel lock-up – transmission and engine control module programming with sp. Under this recall dealers will install new transmission control module software, free of charge. Gm will provide a special coverage program to cover the repair of transmissions that are identified by the remedy software as containing a defective control valve. After the recall service was performed we were told by the dealership that the transmission needed to be replaced. It clearly states under the recall performed that gm is to provide special coverage to cover repairs that are identified by the remedy software as containing a defective control valve. Also, by law, dealers are never to charge for recall repairs. But gm and the d’arcy Chevrolet are refusing to cover the repair costs for the transmission under special coverage program.

While driving my truck it shifts into tow mode by itself, also on June 1st 2025 my truck shifted to 4 low by itself .

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.

When vehicle is placed in park the safety lock will not allow the key to turn to the "off" position and be removed. The vehicle will not turn "off" any further than the accessory position. Sometimes after turning the steering wheel back and forth while working the ignition the key will release. If this does not work after a minute or so, sometimes you can start the truck and immediately turn it all the way off and get the key to release. If all of that fails the last option is to disconnect the battery. It is an intermittent issue that will happen 5 times a day for a week, and then will not replicate again for a week or two.

Component/system: the allison 10?speed (10l1000) transmission valve body catastrophically failed on may?11,?2025, while driving Sunday afternoon down galveston seawall blvd. The truck abruptly dropped from 45?mph into limp mode in heavy traffic, forcing me to pull into the bike lane to avoid being rear?ended. The vehicle remains at classic Chevrolet (galveston,?TX) awaiting the oem valve body—which is on national backorder—and the complete transmission assembly is likewise unavailable. The failed valve body and transmission are available for inspection upon request. Safety risk: unexpected limp mode and gear lock?up in heavy traffic create an immediate risk of rear?end collisions or side impacts as surrounding drivers have no warning of sudden deceleration or loss of drive. Reproduction/confirmation: classic Chevrolet diagnosed and confirmed the failed valve body on may?12,?2025. Their service advisor and my assigned gm case agent (#70179205) have both acknowledged the defect but report no parts available for repair. Inspections: the vehicle has been inspected by classic Chevrolet under warranty. Gm customer care has reviewed my service orders and correspondence. No police or insurance inspections occurred, as no collision ensued—however, the roadside inspection at classic Chevrolet confirmed the mechanical failure. Warnings/symptoms: there were no prior warning lamps, messages, or symptoms before the failure. The valve body failure occurred without any advance indication.

Driving on interstate 10 in arizona transmission suddenly shifted down hard and then into limp mode with check engine light. Took to auto nation gilbert az may 10th they diagnosed valve body failure. Safety was at risk to to vehicle suddenly slowing down in heavy traffic.

While driving to work one day I came to an intersection and stopped. When I went to accelerate to take off my truck shuttered and made a loud noise. The truck immediately went into "reduced power mode" with no warning. I could no longer drive the appropriate speed limit and had to constantly pull over to allow other vehicles to go by. This caused a traffic jam on narrow roads to get the vehicle to a safe spot. My truck only has 43,000 miles on it. The dealership confirmed that the truck has a bad valve body and needs to be replaced. The truck is currently sitting at the dealership and has been since may 15, 2025. As of today, July 18, 2025, gm still does not have an eta on when the part to fix my truck will ship out.

70,000 mile complete transmission failure despite being serviced on-time, as per the guidance. Failure happened while driving and it became dangerous to try to maintain highway speed. Quoted $8390 to replace by the local chevy dealership and quoted 4-6 weeks delivery for backordered parts. This is an unacceptable situation that gm and other manufacturers have artificially manufactured. They design everything to the bare minimum to save fractions of a cent per part, and then they intentionally make the parts unavailable and then the dealership pushes you to trade the broken vehicle in at a massive loss just so you can get back on the road in a newer, more expensive vehicle. This sort of behavior is causing immense financial harm to american families.

My truck has been having the "shift to park" warning for quite a while now. Truck has roughly 72000 miles. Before it would happen intermediately, now it happens all the time. Often I have to leave my truck unlocked for long periods of time due to this malfunction. Hoping my battery will still have power to restart the next time. Reading and researching this issue online, it is a known fact that this is a widespread problem and gm needs to step up and issue a recall.

My business work truck started not shifting properly. I dropped it off at mirak Chevrolet in arlington, MA on 4/29/25 and they diagnosed the vehicle needing a valve body part # 24065357. Gm/Chevrolet has been unable to source this part and was unable to provide an eta. I immediately contacted gm and my case # is 51184758. Then it was approved and escalated for a new transmission and same issue unable to source part and no eta. This is my business vehicle that has not been operable since 4/29 due to a manufacturer issue. No fault on my end. This is a brand new vehicle that should not have these type of issues. I have lost revenue, income, jobs, and I don't have a replacement vehicle. I have a loan on this vehicle that I am making payments towards but there is no end in sight. It has been a month with daily calls to gm for an update or for someone to call me back and nothing. I need my work truck back. This has caused extreme financial stress. I need help.

Transmission was acting funny. Check engine light came on. Took it to a reputable transmission shop who stated it needs a full rebuild due to bad torque converter. $5500. The truck only has 65k mi.
