Transmission failed at approximately 120,000 miles. All maintenance had been done and 90% of miles on vehicle were highway miles. Appears as though there's a thermostat mounted on the exterior of the transmission that is prone to failing around the 100,000 mile area, and when this part fails, there is no transmission fluid circulating to be cooled, so the transmission gets so hot it fails. There are tons of youtube videos from many GM owners that have had to spend thousands and thousands of dollars to replace the entire transmission, when General Motors knows of the faulty part.

STEERING
I’m have 1-2” dead space in steering. It is hard to stay in lane on highway as when a road dip takes extra movement keep straight. I was told this is normal but had dealer change steering box. Replacement helped a lot but truck is starting to get the 1-2” of play once again. Seems like similar issue to 2016 model year.

My transmission had a history of failing trans symptoms, all documented at the dealer from 10,000 miles until it ultimately failed at 127,000 miles. Those symptoms where a down-shift thud, confusion to what gear it should be in, shuddering, shaking and fluid temp running hot without towing a load. Was told by the dealer this was all normal, that the transmission was "still learning". Eventually the trans failed and was towed to the dealer. Dealer said that pieces of the torque converter were found in the fluid and building up in the filter, ultimately clogging it. I had all my recommended maintenance done at the dealer over the life of the truck. Once the trans failed I had an independent service center rebuild the trans, not wanting the same remanufactured trans that failed put back into my truck without any improvements made. No warning lights ever came on.

Transmission failed and truck shut down mid road while going uphill. Shifting jumps when gears are switched and power jumps and goes down while stepping on gas pedal. At first it showed a check engine light but because i was traveling i had to skip and tried turning on again. It happened at least 5 times while on the road that day and now shifting is messed up and jumps while stepping on gas. I inspected and took to a mechanic for an inspection and said need a new transmission unless there is a recall because it happens to many 2018 chevy silverados 1500.

My truck has had transmission issues since we purchased it. At 79,000 miles the factory transmission finally went out and needed replaced. The truck currently has 81,000 miles on it and is already having transmission problems with the rebuilt parts. Background: the truck began having hard downshifts since purchase. Over the course of our ownership, we noticed it started struggling with shifting from 2nd gear to 3rd and 3rd gear to 4th. Constant "clunking" and shuttering when trying to shift. Approximately November of 2024 the truck suffered from the known GM transmission failures. It was almost "skipping" upon acceleration and had a very hard time with cycling between gears. The transmission began making a sound comparable to a normal operating diesel truck (almost sounded like the turbo engines upon acceleration). The truck was sent to the dealership and the transmission was replaced. However, since this replacement we are now experiencing similar symptoms to the previous transmission. There is a very hard downshift, there is clunking sound when the truck is trying to go from 3rd to 4th, and the truck has a noticeable gear burning smell when driven long distances.

I was driving on the interstate and then all of a sudden my vehicle started shaking while driving and by the time I got home in less than 15 miles, the truck was producing huge clouds of smoke out of the exhaust. I took it to a dealership and it was determined the lifters were bad, less than 6 months after I paid off my vehicle and the extended warranty expired. In repairing the lifters it was determined there was a misfire in cylinder 6 which in conjunction with the lifter failure, it damaged rods and pistons to such an extent full engine replace was deemed necessary. I had every maintenance and inspection done on time since the purchase of the vehicle by a local Chevrolet dealership and there apparently was no warning or concern that my lifters were going to imminently fail and/or cause extensive engine damage. My truck was in the repair shop for nearly a 1 year while I waited for a new engine Chevrolet agreed to pay for half of an engine even though I was out of warranty by a few months, but I was under the mileage on the warranty by 30k miles. The truck was not heavily used. Most miles were highway interstate miles from long road trips, but the vehicle largely sat undriven most days of the week for a couple years leading up to the engine failure.
