2016 Chevrolet Silverado 2500 Powertrain (other) Problems

the vehicle developed a extremely hard down shift and then a check engine light came on. the vehicle went into limp mode, took the vehicle to local diesel mechanic and i was informed that the transmission was bad and had to be replaced, while replacing the transmission i was also told the transfer case was making noise and needed to be replaced. this happened in November of 2025 and the parts are not available. This happened while i was towing our trailer across a bridge when the traffic came to a sudden stop, once traffic started moving we could not get up to speed thus causing a traffic hazard. yes the repair shop was able to recreate the issue there were no warnings prior to the failure. I know GM has had issues with transmissions in newer models, i did not know that there was a process like this prior to getting my vehicle repaired and i needed it repaired as soon as possible. that is why i went to and independant repair facility.

At only 71,000 miles the 6L90 transmission had to be replaced in my Silverado because of slippage in fifth, sixth and heavy metal shaving showing in the pan. I have never plowed with this truck or abused the transmission. I've only towed up to 7,000 lbs which is well within specifications. As I continue to talk with other owners of the 6L90 and various mechanics, it has become evident that this particular transmission has a very high failure rate. Unfortunately the core to the failed transmission has already been returned, but what if something major internally failed that locked up the drivetrain and caused an accident? My mechanic John Portal has replaced several 6L90's with multiple types of failures. The only warning I received from the transmission was an engine light which only appeared after the transmission started to fail.

The infotainment center seems to malfunction and push buttons on it's own or not respond to input, which seems related to a more serious problem I experienced where the gauge cluster was not reading anything out when I was driving, including not knowing what speed I was at or what gear I was in. I had to turn the vehicle off several times and restart it several times before the issue resolved.

I was driving down the road, the truck began to shake and bounce real bad. I took to the dealership we purchased the vehicle from and they said $3500 for a new front end to replace all the parts. This truck has never been wrecked or hit anything. This vehicle has 85000 miles on it and its supposed to be a diesel farm truck. It appears the front end was made with parts and material that is not in compliance with industry standards. I was told by the dealership mechanic that the front end could collapse going down the road and injure someone when it collapses. This is on the front end of the truck, the entire front suspension is inadequately equipped with components to maintain the structural integrity of the suspension system.

COMPUTER) IS NOT AVAILABLE AND IT IS NOT BEING PRODUCED BECAUSE OF A DEFECT IN DESIGN. THE VEHICLE HAS BEEN WITH A CHEVY DEALER FOR 10 DAYS. I AM 1100 MILES FROM HOME AND GENERAL MOTORS HAS REFUSED TO GIVE ME A LOANER TO DRIVE BACK TO KANSAS CITY.

I PURCHASED A HEAVY LARGE STEEL CABINET WHICH WAS LOADED ONTO MY PICKUP TRUCK. WHEN I ARRIVED AT HOME, I WAS GOING TO LIFT THE CABINET OFF OF MY TRUCK WITH A JOHN DEERE LOADER. I PARKED MY TRUCK ON MY LAWN. I THEN DROVE THE LOADER UP TO THE TRUCK ON THE DRIVER'S SIDE. I RAISED THE BUCKET OF THE LOADER OVER THE CABINET AND CONNECTED IT TO THE CABINET WITH A CHAIN. I RAISED THE BUCKET UP UNTIL THE CABINET WAS ABOUT 4 INCHES OFF THE TRUCK BED. I GOT OFF THE LOADER AND PROCEEDED TO DRIVE MY TRUCK FORWARD OUT FROM UNDER THE CABINET. I STARTED TO PULL FORWARD SLOWLY WHEN I NOTICED THE BACK OF THE CABINET SEEM TO TILT SLIGHTLY DOWNWARD. I WAS CONCERNED THE WHEEL ON THE CABINET WOULD GET CAUGHT BETWEEN THE SPACE OF THE BED AND THE TAILGATE. I DECIDED TO GET OUT OF THE TRUCK AND RAISE THE BUCKET A FEW MORE INCHES HIGHER. THE ENGINE WAS RUNNING AND I PUT THE TRUCK IN PARK ( THE PARK DASH LIGHT CAME ON) AND I GOT OUT. I WALKED TOWARD THE LOADER CAB. WHEN I WAS HALFWAY THERE, THE PICKUP TRUCK ROLLED BACKWARD, HITTING THE CABINET WHICH WAS SUSPENDED FROM THE LOADER STOPPING THE TRUCK. THAT CAUSED THE CABINET TO STRIKE THE BACK OF THE TRUCK BED, PUSHING IT INTO THE CAB, BREAKING THE BACK WINDOW AND DENTING THE CAB ROOF. THERE WAS OVER $9000.00 DAMAGE TO THE TRUCK. I HAD A $2000.00 INSURANCE DEDUCTIBLE. I HAVE FOUND THAT WHEN I MOVE THE GEAR SHIFT LEVER BETWEEN THE " REVERSE " AND " PARK" DETENTS, THERE IS A FLAT SPOT WHERE THE SHIFT LEVER CAN STAY AND A LIGHT WILL INDICATE EITHER "R" OR "P" DEPENDING WHERE IT RESTS ON THAT FLAT SPOT. THIS ONLY HAPPENS BETWEEN "PARK" AND "REVERSE". WHEN I GOT OUT OF THE TRUCK THE LIGHT INDICATED "PARK" BUT WAS ON THE FLAT SPOT AND HELD IN PARK UNTIL IT SLIPPED BACK TO THE REVERSE DETENT CAUSING THE ACCIDENT. THERE SHOULD BE NO WAY THAT THE GEAR SHIFT LEVER SHOULD BE ABLE TO REST BETWEEN GEARS INDICATING IT IS IN PARK.

WHILE DRIVING MY TRUCK IN 6TH GEAR AT 65 MPH, I APPROACHED A HILL AND I CHANGED THE GEAR SELECTOR TO THE MANUAL POSITION AND TO MY SURPRISE IT WENT INTO 4TH GEAR, RACING THE RPMS UP TO 3500 AND TRIED TO SLOW THE TRUCK DOWN QUICKER THAN I WANTED. THE BIGGER PROBLEM WITH THIS IS SLIPPERY SNOW COVERED ROADS, YOUR APT TO LOSE CONTROL. WHEN YOU DOWN SHIFT TO MANUAL IT SHOULD REMAIN IN THE GEAR YOUR IN,AND YOU PUSH A BUTTON AT YOUR DESCRETION AS NEEDED TO A LOWER GEAR. TOOK IT BACK TO THE DEALER AND THEY SAID THATS THE WAY IT IS,BUT THEY WERE SURPRISED IT DID THAT AS WELL. I FEEL ITS NOT SAFE IT
