Transmission shuttering and rpms surging under normal driving conditions. Shifting hard and shaking the vehicle at highway speeds.

- Newington, NH, USA

Driving on state highway and truck felt like it went into neutral. Pulled to side of road and put truck in park. Put truck in gear and nothing happened. Truck would not move from side of the road. Had truck towed to dealership and was told that the transmission was burnt out and had to be replaced. 2019 Chevy Trail Boss with 90k miles and the transmission fails. Unbelievable.

1st Time I was idling for 30+ minutes, truck was also making strange knocking noises, pulled on to a major highway and rear end locked up, cars were slamming on brakes, almost got killed. Took to shop left for 2 weeks, they said they could find no issues. I assumed they fixed problem, because there was no knocking any more. 3 weeks later, was idling for about 45minutes, pulled into traffic, dark, raining, rear en locked up. Almost got killed a second time. Took in for service and left truck. This needs to be investigated before someone gets killed!

Truck has excessive shuddering accelerating or decelerating. According to the service person at the dealer it is a problem with moisture and the factory fluid that the truck came with. Diagnostics showed excessive TCC Slippage which requires and upgraded transmission fluid. The TCM was also reprogrammed with the latest calibrations. Total cost $654.30.

6L80E 6 speed transmission. Vehicle slips at low speeds, under light acceleration. Sometimes when it shifts, its very hard and jerky. If this is normal designed operation, the transmission or programming needs to be redesigned.

Event in Order: -AutoStart, failure -Started with key --€œAction Required-€ - -€œSteering Assist Is Reduced, Drive with Care-€ --€œService-€ - -€œTrailer Brake System-€ --€œdash panel information-€ not available -€" Fuel Economy and oil life --€œTraction Control light on-€ -Put truck in reverse, gear not engaged, no response -Put truck in drive, worked, but steering very difficult and made vehicle not safe to drive and/or operate. This has happened to me once before but not to this extent, last was when I was driving and thankfully I was able to pull over and turn the vehicle off. It would not start after repeated attempts but finally started after and functioned normally. These events had not check engine lights and when serviced, the mechanics said they didn-€™t see anything when scanned. OnStar diagnostics had no report when I had it active. I bought this truck less than 18,000 miles ago. Initially bought at 17,181 miles on Feb 22, 2021 and is now at 34,675 miles as of Oct 29, 2021. This is a safety concern as the steering fail can potentially lead to an accident if the truck can-€™t be controlled. Traction control failure can lead to the vehicle becoming stalled in a dangerous situation. Brake systems can lead to unwanted breaking and/or being unable to break. This truck is a danger to operate. I do have video but, upload does not support MP4 format.

Same issue I had with my 2017 Colorado. Shutter/shake when accelerating between 1 & 2. Issue started around 64k miles. Thought maybe it needed the same transmission flush to the newer fluid. Dealer called after 4 days of holding my vehicle (with no loaner or rental option) to tell me that the trans needed an "update" and that it would cost me over $500 since I was over warranty at 67k. There's already a bulletin for the Camshaft Position Actuator Magnet Replacement, which supposedly memics the same issue. However the dealership says "that's not the problem". I'm sure the same trans issue with hard gear shifts is probably related to this issue now. I haven't felt the hard gear shift in a while but it would do it randomly when accelarating out of my driveway.

Truck lunges forward sometimes. It will work properly most of the time and then after stoping, when you tramp on the gas it will hesitate then lunge forward. As I said most of the time it works properly. I consider this a very real hazzard, has been doing this for months. One day at my golf club while pulling into my parking spot, a tight fit, I had to back up to get into my spot. When I tried to go forward it had about a two second hesitation then squealed the tires. I have witnesses. My dealer says everything with the truck is normal after they inspected it. The internet is full of the same thing from other owners of the same truck.

On September 11 at approx. 1630 hrs. my wife and I were going out for dinner. I stopped at a stop light on a hill. Transmission in Drive, foot on the brake. Our truck suddenly started rolling backward. I looked at the dash, no warning lights, gauges still working, transmission in drive, I stood on the brake pedal, no effect, I put the transmission in park, no effect, I engaged the parking brake, no effect other than the parking brake warning light came on. We had rolled back approximately 50 feet. I looked in my rearview mirror and observed a car approaching. Luckily he/she saw my problem and stopped. Things suddenly started coming back to life and came to a gentle stop. When I looked in my mirror I was so close to the car behind me all I could see was his windshield, no hood. I moved the transmission from park to drive and we continued on. I have contacted the dealer and they are attempting to determine what happened. However, I am afraid this will happen to someone else who may not be as lucky as I was or that it may happen to me again. I pull a 5th wheel trailer with this truck.

My truck has a vibration when going down the highway at speeds of 70 mph. The dealer has done a transmission flush but still have the same issue. I am afraid that the driveshaft or the transmission may lock up while we are on the highway with the family.

- Lake Alfred , FL, USA

When backing out of the driveway and shifting from Reverse to drive the transmission slows the engine before slamming into second gear. During the entire driver the transmission shakes before shifting into any gear. I took it to Patriot Chevy in Warminster, Pa on 8/2/21. They said they reset the computer module. I tested it immediately and nothing changed.

- Hatboro, PA, USA

When shifting from reverse to drive the transmission makes a hard slamming sound. It also shutters when driving 70 mph. The dealer told me it-€™s normal.

- Sulphur , LA, USA

I purchased this vehicle back on February and noted that the transmission is kicking hard from first to second gear shift at all times. Went to the dealer and told me tech cannot find nothing wrong and that this is normal as is a 9 shift transmission. When at a fast food full line this vehicle shifted so hard that I almost hit the car on front on me. Having cars all my life and be a mechanic, I can tell you this hard shifting is a safety issue.

- Richmond , VA, USA

The transmission will sometimes hesitate/lag for a few seconds when shifting from 1st gear to 2nd gear. This seems to occur only cold starts where the vehicle has sat for a long period, such as overnight. On the most recent occurrence, I was stopped at a stop sign on my road and began to turn left (northbound) on to the busy highway. While turning from the stop sign on to the highway, the vehicle vehicle hesitated mid-shift and I lost acceleration. After a few seconds, a loud clunk was then heard, the truck jerked - throwing me forward, and acceleration was restored. This delay resulted in a near-miss collision as there was an approaching vehicle headed southbound and I was stuck in their lane since my vehicle was not accelerating. Issue reported to Heartland Chevrolet (501 Rte 291, Liberty, MO 64068) to document and investigate the issue. Vehicle taken to dealer next day. After 3 days of service, the dealer service team could not reproduce the issue and escalated to regional GM engineer (Service Manager called him directly.). Engineer stated that hesitation is normal. Still an on-going issue; work around has been to let the vehicle idle longer before driving on a cold start. Sometimes you can "feel" the hesitation and know when to let off the gas pedal few a few seconds until the shift in to 2nd to avoid the vehicle throwing you forward, being able to have better "control" of the hesitation issue.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that at start-up and occasionally while driving at various speeds, the steering wheel ceased to operate as designed. Additionally, the vehicle occasionally failed to respond when shifted into drive however, the reverse gear worked as designed. The power steering assist warning light was illuminated. The contact recently noticed that the rear driver's side seat belt was not stitched properly. The seat belt strap loosened while attempting to secure his child in the seat belt. Mtn view Chevy (310 E 20th St, chattanooga, tn 37408) was made aware of the failures and informed the contact that the vehicle was over the warranty coverage and there were no recalls associated with the failures. The manufacturer was made aware of the failures and opened a case but informed the contact that recalls were VIN specific and the VIN was not included in any recalls associated with the failures. The manufacturer referred the contact to an authorized dealer to have the vehicle diagnosed. The approximate failure mileage was 44,000. Invalid VIN.

My transmission is shifting really hard particularly at slower speeds. When I begin to slow and then start to accelerate just a little bit it slams into gear at times causing the truck launch forward. I have had it back to the dealer no less then 4 times for the issue. They tell me the same thing every time. If we don't have a code or can't replicate it we can't fix it. From research I have done this seems to be a wide spread problem! I have real safety concerns. Specifically if it does one of these hard shifts while I am in traffic, I am afraid it will push me right into the back of the car in front of me.
