It was light at first but lately its been worse. I took it to the dealership a couple of months ago & they replaced something small & said it was fixed. But it still bad. My truck still only has 30K miles.

The contact owns a 2019 GMC Sierra 15000. The contact stated while driving approximately 5 MPH as the vehicle was placed into "drive" the transmission, would hesitate and would not shift into gear. The contact stated that when the "drive" engaged, the shift was very hard and shook the vehicle, which then lunged forward. The contact stated that the "check engine" warning light was illuminated. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that there was no transmission failure. The vehicle was not repaired. The contact stated that the transmission failure is recurring. The manufacturer had not been informed of the failure. The failure mileage was approximately 7,000.

when I bought the vehicle in October2018, I have taken the vehicle back to the dealership multiple occasions and they refuse to fix this issue. The transmission shifts from first to second gear or second to first gear is clunky, jerks forward and shifts without warning. While sitting at a stoplight, the vehicle will sometimes lurch forward several inches without warning even with your foot on the brake. Furthermore when accelerating between first and second year it's sluggish and takes several seconds to shift from first to second the engine Revs high.

Hard shift on take off from 1st to 2nd gear and while driving around random hard erratic shifting. Feels like pickup is getting rear ended. Have take in to Gregg Lair in Amarillo TX and they have reset shift points to no avail. I talked to head service writer and he stated that GM had a problem with their transmission but did not have a remedy for them. He advised to drive for about 3,000 miles and we have and still have the issue. We have been back multiple times and Gregg Lair states that it is still in learn mode after over 10,00 miles. I am a mechanic by trade and in my opinion there is a design flaw with the transmission and/or they have the wrong transmission fluid for the design.

The 2019 GMC SIERRA I own shifts extremely hard from a stopped position or when changing from reverse to drive. The shift is so forceful, that it feels like I have been struck by another vehicle. The overall feeling is that the vehicle is not safe to drive and it is not a reliable mode of transportation. The delayed shift, vibration and jerk, makes this vehicle a hazard to drive, as the ability to predict the issue is impossible. There are no other warning lights, or messages prior to the error. Online forums show this to be a known issue.
Power train, Vehicle speed control, Jan 10, 2022
Transmission jerks, slams, forces a feeling of being rear-ended, delayed acceleration with sudden engagement causing uncontrolled acceleration. I've had it looked at every time I've taken it into the dealership for regular maintenance. They haven't been able to reproduce it as it only happens once, first time after not driving it for a while. No warning lamps or messages ever appear.

WHILE DRIVING THE VEHICLE 21OCT2020 IT STARTED WHINING AND JERKING. I CALLED THE DEALERSHIP TO HAVE IT CHECKED THEY COULDN'T SEE US, SO WE TOOK IT TO A DIFFERENT GMC DEALERSHIP THAT SAID THE CODES HAD NOT BEEN UPDATED, THEY PREFORMED THE RECALL AND SAID IT SHOULD BE FINE. TWO DAYS LATER IT STARTED JERKING AGAIN AND SHUT OFF WHEN STOPPED AT A LIGHT. I TOOK IT TO THE GMC DEALERSHIP WE BOUGHT IT FROM ON THE 28OCT2020 AND I WAS TOLD THAT THE TRUCK WAS FINE, AND THAT THE DIAGNOSTICS SHOWED NO PROBLEMS WHATSOEVER. THE TECH SAID HE WOULD DRIVE IT OUT OF THE BAY, IF BRITTANY WOULD OPEN THE DOOR AND BEFORE HE COULD DRIVE IT THROUGH THE GARAGE BAY AREA AND OUT THE GARAGE BAY DOOR THE TRUCK MADE A CRAZY LOUD NOISE, JERK TO A SUDDEN STOP AND THE TRANSMISSION WENT OUT, AND THE TRUCK WOULD NOT RESTART AT ALL AND HAD TO BE TOWED OUT OF THE BAY DOOR. THE 2019 TRUCK HAS HAD 5 RECALLS FOR SAFETY ISSUES AND WITH 40,000 MILES THE TRANSMISSION WENT ALL THE WAY OUT AND THE TRUCK HAS BEEN SITTING THERE AT THE DEALERSHIP FOR OVER A MONTH WAITING ON THE NEW TRANSMISSION TO COME FROM GMC. I GO IN AND SEE THE TRANSMISSION RECALL ON SO MANY 8 SPEED TRANSMISSION WHICH THIS TRUCK HAS, AND NOW I FEEL LIKE I WAS SOLD A LEMON AND NO ONE SEEMS TO CARE. % RECALLS AND THE TRANSMISSION GOES OUT COMPLETELY AT 40,000 MILES. I AM SO UPSET ABOUT IT THAT I DO NOT EVEN WANT THE TRUCK ANYMORE. IT IS GOING TO RUIN MY RESALE VALUE AND THE LEMON LAW SHOULD APPLY ON A TRUCK ONE YEAR OLD. I HAVE FILED COMPLAINTS WITH THE DEALERSHIP, AND NOW ON THEIR FRONT DOOR IS A SIGN THAT SAYS THEY WILL NOT HONOR THE WARRANTY POLICIES ON ANY VEHICLE THEY SOLD AFTER NOVEMBER 15, 2020. OF COURSE THEY SOLD ME ZURICH EXTENDED WARRANTY TOO, AND I CAN PROMISE I WILL NEVER BUY GMC AGAIN. I ALSO HAVE A 2017 PATHFINDER ALMOST PAID OFF, THAT I AM GIVING TO MY DAUGHTER, AND I WAS GOING TO GET AN GMC ARCADIA BUT NOT A CHANCE NOW.

PULLED ONTO THE MAIN ROAD AND APPROACHED A STOP LIGHT WHEN THE TRUCK STOPPED A LITTLE HARD AS I WAS DEPRESSING THE BRAKE PEDAL. AS I STARTED PRESSING ON THE GAS WHEN THE LIGHT TURNED GREEN, I WAS TRAVELING AROUND 35 MPH OR SO, WHEN THE TRUCK CAME TO A COMPLETE STOP IN WHICH MYSELF & PASSENGER WERE SLIGHTLY THROWN FORWARD DUE TO THE ABRUPT STOP FOR NO APPARENT REASON. THE VEHICLE IN BACK OF ME NEARLY REAR ENDED ME DUE TO THE ABRUPT STOP THE TRUCK DID. I IMMEDIATELY CONTACTED THE DEALER, IN WHICH AFTER SEVERAL DAYS IN THE SHOP, THE DEALER TOLD ME THAT GMC KNEW ABOUT THIS PARTICULAR ISSUE BUT HAS NOT ISSUED A RECALL. THE DEALER WAS INSTRUCTED TO REPLACE THE TRANSMISSION CONTROL MODULE, DUE TO A MALFUNCTION IN THE TCM THAT APPARENTLY WAS TRYING TO SHUT THE TRUCK DOWN COMPLETELY.
