2017 Chevrolet Silverado Powertrain & Transmission Problems

Transmission is hunting for gear when decelerating. Back and forth it tries to change gear. Just started. I have 64,000 miles on the truck. At 22,000 it started shuddering and the fluid was changed which corrected the issue then. At 53,000 the shudder returned and I paid the dealerdealership to replace the torque converter. Now 12,000 miles later I'm having a shifting issue. This Transmission seems to be problematic.

A well known issue with the torque converter failing due to poor manufacturing and design. Allowing debris to enter the filter system due to the torque converter falling apart. Causing astronomical amounts in repair costs

approximately, on or about [XXX], while driving our Chev Silverado, VIN as noted [XXX] ) started to experience transmission issues when i started from a stop sign and it started hesitating upon acceleration, jerking (gears not meshing correctly every time i had to stop). This included delayed engagement of gears, roughing shifting, slight slipping of gears, at times i could smell a burning like smell, (No leaks noticed on transmission anywhere and no warning lights coming on to warn about Transmission problems). On Jan 23rd, 2026, i took it to B&F automotive had mechanic check fluid level and do drive test with me. Fluid found to be good. I could hear a slight sound like high pitch sound at times, only last few seconds randomly). Mechanic suggested i put some fuel system cleaner in and 90 Octane to hopefully clear the system. dealer also suggested this just as a suggestion though they found no apparent issues during prior service oil change I just had dealer do a 27-point inspection with oil change and they did not notice issues. Since purchase of truck in 2019, from dealer, all services have been done only by dealer (Woodland Motors). we had bought extending service warranty with vehicle. According to dealer, it just expired Dec 2025. I currently have appointment to have dealer inspect it on Monday Jan 25th, 2026, at 1pm concerning our complaint of drive train issues. Current mileage is approx. 63, 060 miles. on advise of mechanic, i called dealer right away and set the above appoint. I explained to dealer rep that this will cause me financial hardship as i am [XXX]. i do maintain a maintenance file with all service records since purchase.

1. The vehicle's transmission does not operate consistently and safely. 2. At times, the transmission will not engage, and this has placed my family in very dangerous situations when changing lanes. 3. At red lights, at times, the transmission will not engage to drive. 4. When slowing in traffic at times , the transmission will not adjust to the slower speed, although the operator is applying the brakes. Then, without warning, the transmission will engage the higher speed, almost launching the vehicle forward suddenly, potentially into another vehicle or person, depending on the situation.

NHTSA Safety Complaint To: National Highway Traffic Safety Administration (NHTSA) Regarding: Vehicle Safety Hazard / Fraudulent Repairs on 2017 Chevrolet Silverado VIN: [XXX] To Whom It May Concern, I am writing to file an emergency vehicle safety complaint regarding a 2017 Chevrolet Silverado, VIN [XXX], purchased on XXX. Huntley Ford performed unauthorized, fraudulent, and unsafe repairs that resulted in the vehicle being returned to me as an active fire hazard, directly violating federal motor vehicle safety expectations. Huntley Ford forced a salvage engine onto the vehicle, stripped me of my repair rights, and intentionally cleared dashboard error codes to mask severe, systemic mechanical defects. Following an engine replacement, transmission replacement, and catalytic converter replacement, I took the vehicle to Sunrise Chevrolet for inspection. The technician at Sunrise Chevrolet discovered that the vehicle was actively burning fluid onto the alternator. The technician explicitly stated that the vehicle was a fire hazard and that there was an emergency safety brake problem, and brakes. Huntley Ford knowingly delivered a structurally compromised and life-threatening vehicle. I request a full investigation into Huntley Ford’s repair safety practices to protect the public from further hazardous non-compliance. I have a 16 page paper trail Word document letter proving Huntley Ford committed auto fraud, has practiced illegal practices, lied, sold us a truck that they cleared codes, after only a few months full transmission, c. converter replacement, engine, and did not fix the truck properly still, returned it back to us when they knew it was not ok, lied, cleared codes, we brought our own scanner, they lied again, said the codes just needed to be cleared. When we notified [XXX], Huntley Ford's repair manager, he did nothing. Sincerely, [XXX]/[XXX] ________________________________________ INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving on Highway 35 in Austin, Texas, my vehicle's transmission unexpectedly failed, which placed myself and my passengers in a precarious situation. The vehicle became inoperable on the side of the highway, necessitating that my passengers and I manually push it while traffic was actively flowing. This mechanical issue occurred without any prior indication. Through my subsequent research, I have observed that this particular problem appears to be a recurring concern with this model of vehicle.

Bought the truck brand new, after 20,000 miles started vibrating. Took it to the dealership said it was the transmission shutters. They changed the fluid. At 50,000 miles did it again, they said GM came out with a thicker fluid, but it in there. Was fine for a while. At around 135,000 miles getting the vibration again. Also, at 140,000 miles cylinder 8 misfiring. Took it in and they tore it apart and said cylinder 4 and 8 lifter failure. Damage to cam and bent rods. Had to replace all lifters, cam and rods. Cost over $10,500, but had BG warranty used that additive every oil change so BG covered $4,000. I went by the oil life indicator on the truck to determine when I needed to change it, but apparently for engine for life you have to change it more frequently at 6,000 miles, so they wouldn’t cover that part.

The contact owns a 2017 Chevrolet Silverado 1500. The contact stated while driving approximately 25-35 MPH from a complete stop at a traffic light, the RPMs increased to 4,000 before the transmission shifted into gear. The contact was able to drive the vehicle. The contact immediately pulled into a relative's driveway and parked the vehicle. The vehicle was towed to a certified mechanic, where it was diagnosed that the torque converter had failed. The torque converter was scheduled to be replaced. The manufacturer was informed of the failure and informed the contact that recalls were issued by the NHTSA. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 71,000. The VIN was not available.

Transmission went out while driving the vehicle and left it stuck in the middle of the intersection we had to push it though traffic. It had no forward movement. Would only drive in reverse. No warning or anything just made a clunk and wouldn't move any further.

See attached document for complaint.

The transmission started to shutter at 94,000 miles. Gwatney Chevrolet quoted $7,500 for a new transmission replacement. Had an in independent shop quote $4,670 for a reman transmission. I have only towed 2,000 lbs at a time in the past. This is the 1st time towing a 6,000lbs camper. It was only driven 800 miles with the camper in tow. The vehicle only has less than 95,000 miles and my transmission is shuttering and has metal shavings in the fluid. Needing a replacement at this time frame and mileage is ridiculous.

Transmission failure, I had to have the transmission replaced and no longer have it for inspection. I was on a one lane highway in Franconia NH with guardrails on each side, and no phone reception. Traffic was trying to get by me including tractor trailers, we were horrified and couldn't get out. these 6L80 transmission in the Chevy Silverado, come to find out, have been failing for a long time. 2 of my friends lost there's also, all of us were between 100k-115K miles. The transmission shop I went to, and others I called said they can't believe there was never a recall, they get many of them. Zero warning, just quit. I take exception care of my vehicles regarding maintenance, always early, these are to expensive to repair when your on a retired budget.

Hard jerking while driving clunks while driving shifts rough really bad when driving changes gears its an automatic stalls at lights runs rough jumps forward has no power at times brakes fail when stopping lunges when breaking Dealership and manufacture know about this Its been to dealership over 9 times same problem

I am having the exact transmission issue for this truck that has been recalled, but when I call to get it serviced, I am told "there isn't any unrepaired recalls. This issue is persistent and unresolved. Please look into this and potentially recall the transmission issue. This truck has constant shifting troubles form 1st to 2nd with shuddering.

I was driving to work last Monday when my truck entered a lymph mode. It would only let me go 40mph, when I was on a road that allowed others to go 60-70mph. I had traffic behind me as well. As I made it closer to work, the truck would only rev up. It left me sitting in a median with traffic going past me. Thankfully, I was not hit. I had to cut the truck off, wait several minutes, then start it back up to limp it to a safe spot where I could have it towed. I had it towed to a transmission shop. Please note* I have done the regular transmission maintenance on this vehicle as well. This shop done a diagnostic test on it ($95 +tax). It was a complete transmission failure. They told me this was due to the torque converter. General Motors, GM, programmed the transmission torque converter to kick on in 2nd gear which causes it to overheat practically everytime it drives. The same transmission shop said they rebuild 3-4 of the 6L80 transmissions a week. I have a 2017 chevy silverado with a 6 speed transmission, the 6L80..... This is an issue that GM should be held liable for. The transmission rebuild will be $4500-4800 + tax. Thank you to whomever reads this. I could really use help. My email is [XXX] . Phone number is [XXX] . I can provide rebuild cost and receipts when needed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have lost my brakes when reversing, however I have good brakes when driving forward. The transmission is also slipping and the torque converter in the transmission is becoming very worn ALREADY. I do not tow anything with this vehicle, and I only have 73,411 miles on this truck.

I own a 2017 Silverado 1500 ecoTech V6, 6L80 transmission, 91500 - over the weekend, I started having an issue shifting from 3rd to 4th. I noticed the transmission was over 190 degrees, as high as 230 degrees, then cooling back to 194. When attempting to shift from 3rd the 4th, it will start, then return to 3rd. It will do so 4 or 5 times until eventually skipping 4th and going to 5th. This happens when the transmission fluid is cold, 80s or when fluid gets to 190+. I called the local Chevy deal, who told me there weren't any open recalls for my VIN and that the diagnostics would be $190 which may or may not be a software update. They would not know until after the disanostics.
