2018 Chevrolet Silverado 2020 was under warranty (22,000 miles)-??.felt a little vibration in my steering wheel and suspected a transmission problem and called the dealer-??s service department. I told them what I felt and they said-??yes you have a transmission problem (that Chevrolet knows about) bring it in and we will fix it. The fix was-??change transmission fluid to synthetic. Now I was not comfortable with the repair but what can I do. I also know changing to the synthetic fluid can handle higher temperatures and will not breakdown as quickly. So my point is Chevrolet knows and knew about the problem and did not even think about a recall due to the expense it would cost them. Chevrolet expects me to absorb the cost of a manufacture problem. Last year was the start of my families transmission problems. It started May of 2023 with my 2014 Silverado-??s transmission (175,000 miles) and ended up getting it overhauled. The truck was not abused. November my 1st grandson-??s 2018 Silverado-??s transmission failed, December 2nd grandson-??s 2015 Serria-??s transmission failed. I also recently (3 days ago) found out my friend-??s 2018 Silverado went failed last year. All within a 6 month-??s period. Now I have lost my 2018 Silverado transmission (mentioned above) with 88,000 miles. This is just my family-??I really can-??t imagine what is going on country wide. All of the above events has prompted me to look into this problem. Every transmission shop and dealer is telling me Chevrolet knows and knew about the problem-??I can go on. I am very concerned and will not stop at getting resolve with GM/Chevrolet taking ownership of the transmission problem. Sure I want help...but I also want to help others with the same problem.
P1. On or about Feb 9, Power Train transmission, Modular-??s. While traveling about 40mph the truck shifted suddenly to low gear, and the water pump blew resulting in steam or smoke from engine hood. Automatic shifting was not possible, after slowing to 5-10 mph check if mauls shifting was an option. All gears L1 L2-??were replaced with -??L-??. P2 March 2023 to presented 2024, the vehicle will vibrate and shake. More like a shimming. This happens what seems to be every.5 to 1.0 mile. P3 March 2023 The Transmission issue listed in para 1 happen exactly as describe above. Except the water pump was fine. On or about June 2021 The Transmission issue listed in para 3 happen exactly as describe above. I TOOK TRUCK TO HENDERSON CHEVROLET in Henderson, NV and reported the transmission sudden shift to low AND how the truck slams into gear when leaving a stop sign light. It feels like someone hit the back of the truck. Jerks forward. Service RESULT: that-??s normal for the truck. October 2019, took truck to back to Circle Chevy / Hyundai in Shrewsbury NJ regarding the slamming and jerky transmission. RESULT: it-??s normal or it didn-??t do it while in service road test. I just bought the truck 1 month earlier from CIRCLE CHEVY of SHREWSBURY NJ. Regarding the most recent trans issue of Feb 2024, the power train went out of warranty in August. The issues should have been fixed when odometer was between 000064 to 60000 or Aug 2024. This truck is unsafe and sudden shift to low gear can cause the truck to get into accident
Vehicle wouldn't accelerate while in moving traffic. Rpm gauge would move but speed gauge would not and vehicle would not accelerate past 30-35. When I pulled over and put my vehicle in park then attempted to put in drive, it would not move. Transmission light turned on. Had it towed to a mechanic who after diagnostics, states it's definitely the transmission/torque converter.
unknow getting gas in oil at 62532 miles on it which can cause the motor to grenade. a lot of the 5.3l on 2018 has this trouble from watching utube and using research, should be recalled and transmissions trouble as well.
I purchased this vehicle from Galles Chevrolet in Albuquerque New Mexico as a certified pre owned vehicle. Couple of days after I noticed a vibration coming from the front steering and drivetrain I immediately took it back to Galles and they told me nothing was wrong with it and that the aggressive tires was what I was feeling. So I took it back and drove it for a couple of weeks and the vibration started getting worse so took it back again they rotated and balanced the tires and said it was fine. A few weeks passed and it started again took it back and told me tires were out of round and that was what I was feeling 21/2 months it sat in the back lot until they figured out who was gonna replace the tires. Finally got the truck back and it was ok until the new tires started cupping again and the vibration was back in total I took it in about 8 times in past 18 months for the same issue and to this day has not been resolved. According to GALLES CHEVROLET the technician stated that that was normal for a 2500 4 wheel drive truck with aggressive tires drives and assured me that there-??s nothing wrong with the vehicle. Now look at the video and tell me if that-??s normal for this truck For some reason it-??s not letting me load a video of me moving the wheel up and down side to side where it moves about 3-?? with the steering wheel locked wheel is very very loose
The GM 6L80 transmissions have a faulty torque converter. When it goes out it causes a horrible vibration and drive train failure. Which leaves you stranded in traffic or on the side of a busy highway. These transmissions have been installed by GM since 2013 knowing they fail prematurely as early as 60k miles. It-??s a running joke that this transmission saved repair shops because of the sheer amount of failures. With the cost passed on to consumers. There are several in detail breakdowns of the defect in this part on various social media platforms and Internet forums. You can call any transmission shop across the nation they can confirm the defect. There where no warning lights prior to, during, or after the failure.
The transmission caused a vibration and sometimes a surge when it would go into gear. I had to be very careful when initially driving forward, especially in heavy traffic making sure I had a safe distance ahead of me. The entire vehicle would shutter when accelerating almost at any speed.
Have 2018 Z71 Silverado truck after a few thousand miles I notice vibation when speed was around 65mph even the passage seat was vibrating and sometime the hard shift like you was hit from behind when shift went online to see if anyone is having this problem and there was something about the Chevy shake

My vehicle has been properly maintained since new. At around 90,000 miles the transmission started making noise. I had trans filter changed and the noise abated. at 92,000 the car started shifting oddly. Several times on the highway the engine would rev and the car loses speed. Loud noises from the transmission and hard shifts. I most recently was unable to accelerate while getting on the highway. This is a truck, I have things I have to transport. I am unsure if I should continue to drive on the highway. I am going to my local dealer next week to explore repair options. I have learned that this problem is well-known to GM.
