2019 Chevrolet Silverado 1500 Power Train

THE POWER TRAIN DELAYS SHIFTING FROM 1ST TO 2ND GEAR RESULTING IN HESITATION IN FORWARD MOVEMENT OR A VERY HARD, ABRUPT LURCHING FORWARD SHIFT. THIS HAPPEN ON THE FIRST DRIVE OF THE DAY AND THEN INTERMITTENTLY THROUGHOUT THE DAY. BOTH TYPES OF SHIFTS CREATE UNSAFE CONDITIONS. IT SEEMS THE ENGINE POWER IS LINKED TO THE THE SHIFTING ISSUE AND EITHER NOT ENOUGH OR TOO MUCH POWER IS APPLIED AT THE SHIFT POINT. IN ONE INSTANCE THE POWER TRAIN WAS CONFUSED AND COULD NOT DECIDE WHETHER TO BE IN 1ST, 2ND OR 3RD GEAR AND SHIFTED UP AND DOWN WHILE I WAS ATTEMPTING TO NAVIGATE CONGESTED CITY TRAFFIC AT SLOW SPEED. GM SERVICE BULLETIN 20-NA-102 AND 16-NA-361 SUGGEST THAT THE POWER TRAIN BEHAVIOR IS NORMAL. WHEN I RETURNED THE VEHICLE FOR SERVICE, THIS WAS THE DIAGNOSIS. DISCUSSION WITH THE SERVICE ADVISOR INDICATED THAT IN SOME INSTANCES OTHER ACTIONS ARE TAKEN TO ADDRESS THE SITUATION, BUT IT IS NEVER ELIMINATED. NOW CUSTOMER SATISFACTION PROGRAM N192272400 HAS BEEN ISSUED DUE TO A FAULTY TCM WHICH CAUSES THE WHEELS TO LOCK UP. THIS SHOULD BE AN URGENT RECALL. THESE COMBINED CONDITIONS CREATE AN UNSAFE VEHICLE THAT NEEDS TO BE ADDRESSED AND CORRECTED.

RK PURCHASED A 2019 CHEVY SILVERADO LT 4X4 CREW IN 12/2019 RIGHT FROM THE START NOTICED HARD UNSETTLING LUNGING IN TRANSMISSION WHILE CHANGING GEARS FROM REVERSE INTO DRIVE.( HARD JOLT -LUNGING ) IT WOULD, AT TIMES JOLT HARD ENOUGH TO SLOSH DRINK FROM CUPS INTO THE CUP HOLDER/ OR LAP !. AT APPROXIMATELY 2500 MILE RANGE THE TRANSMISSION ACTUALLY CEASED UP, WOULD NOT GO IN REVERSE NOR DRIVE. THE ENGINES RPM HAD SHOT UP TO 2500 -3000 RPM'S AND WOULD BARLEY CRAWL. HAD IT TOWED IN TO DEALERSHIP . REPROGRAMMED THE COMPUTER AND STATED THAT THIS SHOULD FIX THE ISSUE , . BUT IT DIDN'T , STILL LUNGES AND JOLTS PRETTY MUCH EACH MORNING OR AT UNSUSPECTED TIMES WHILE SHIFTING FROM REVERE INTO DRIVE. CURRENTLY HAS 6200 MILES NOW 4/2020 .HAVE CONTACTED GM AND RECEIVED A CASE NUMBER THAT NO ONE SEEMS WANTING TO ADDRESS AT THE GM -CHEVROLET HEAD QUARTERS. HAVE CALLED FROM 3/24/2020 UNTIL 4/9/2020 NO LIVE PERSON HAS ADDRESSED (VM AFTER VM)

EVERY MORNING SINCE VEHICLE WAS NEW HAS 2600 ON IT NOW WHEN COLD I PULL OUT ONTO STREET WHEN VEHICLE SHIFTS FROM FIRST TO SECOND GEAR THE SHIFT SHIFT SLIPS AND FLARES LIKE IT S IN NEUTRAL AND VEHICLE WILL HESITATE SLOW DOWN WHILE IT'S WAITING TO GET INTO SECOND GEAR, THIS IS A SAFETY ISSUE BECAUSE THEIR IS NO FORWARD MOVEMENT DURING THIS AND POSSIBLY COULD CAUSE AN ACCIDENT BECAUSE VEHICLE WON'T MOVE QUICK ENOUGH, AFTER SHIFT 2-3 IS PERFECT AND 3-4 WILL DO SAME THING SLIP AND FLARE, I'VE BEEN TOLD THIS IS NORMAL BUT I AM A AUTOMOTIVE TECH AND HAVE BEEN FOR OVER THIRTY YEARS THERE IS DEFINITELY SOMETHING WRONG WITH TRANS BUT GM WON'T ADMIT PROBLEM THIS IS WIDE SPREAD AS THERE ARE THE SAME OTHER COMPLAINTS ON THIS WEBSITE.

THE POWER TRAIN DELAYS SHIFTING FROM 1ST TO 2ND GEAR RESULTING IN HESITATION IN FORWARD MOVEMENT OR A VERY HARD, ABRUPT LURCHING FORWARD SHIFT. THIS HAPPEN ON THE FIRST DRIVE OF THE DAY AND THEN INTERMITTENTLY THROUGHOUT THE DAY. BOTH TYPES OF SHIFTS CREATE UNSAFE CONDITIONS. IT SEEMS THE ENGINE POWER IS LINKED TO THE THE SHIFTING ISSUE AND EITHER NOT ENOUGH OR TOO MUCH POWER IS APPLIED AT THE SHIFT POINT.

WHEN I TAKE OFF THE TRUCK JERKS AND SHAKES UNTIL ABOUT 5-10 MPH. IT SEES LIKE THE TRANSMISSION IS NOT GOING INTO GEAR. IT HAPPENS WHEN I FIRST TAKE OFF TO GO. *TR

MY TRUCK WHEN IT IS IN THE CITY AND I?M APPROACHING A STOP SIGN THE TRANSMISSION MAKES THE VEHICLE SHAKE. THE AGGRESSIVE SHAKE ONLY HAPPENS WHEN I?M BRINGING MY TRUCK TO A STOP AFTER GOING PAST THE FIRST GEAR. IT CAN HAPPEN IN THE CITY AND HIGHWAY, BUT THIS ONLY HAPPENS WHEN THE VEHICLE GOES PAST THE FIRST GEAR AND BRINGING THE VEHICLE TO A COMPLETER STOP. I GOT THE VEHICLE CHECKED OUT AND THE DEALER MECHANIC ASSUMED THE PROBLEM WOULD GET FIXED AFTER UPDATING MY TRUCK FROM THE RECENT BREAK RECALL. BUT UNFORTUNATELY THE SHAKING WHEN I PUT MY TRUCK TO A STOP STILL CONTINUES. *TR

TRANSMISSION SHUTTERING AT LOW SPEED CAUSES VIBRATION IN THE STEERING WHEEL ON EIGHT SPEED TRANSMISSIONS. TWO VISITS TO DEALER. TRANSMISSION FLUID CHANGED, NOT CHANGE. INFORMED THIS IS INHERENT IN THIS TRANSMISSION, JUST HAVE TO LIVE WITH IT. DOES NOT SHUTTER IN MANUAL MODE. READ FLORIDA HAS PENDING LAW SUIT FILLED. VERY UPSETTING SPEND THIS KIND OF MONEY FOR SOMETHING GM SHOULD BE ABLE TO EITHER FIX OR REPLACE TRANSMISSION. HAPPENS EVERY TIME TRUCK DRIVEN IN (D) DRIVE MODE.

TRANSMISSION WILL HESITATE AND SHIFT VERY HARD FROM 1ST TO 2ND GEAR ESPECIALLY IN COLDER WEATHER. THIS HAS HAPPENED SINCE I PURCHASED THE TRUCK. DEALER CHANGED TRANSMISSION FLUID AND SAID HARD HESITANT SHIFT WAS NORMAL.

THIS PROBLEM OCCURS AFTER THE VEHICLE HAS BEEN DRIVEN ANY DISTANCE, BUT FAR ENOUGH TO SHIFT GEARS IN THE AUTOMATIC TRANSMISSION AND WHEN THE AUTO ENGINE STOP IS DEACTIVATED MANUALLY OR AUTO ENGINE STOP DOESN'T ACTIVATE DUE TO DRIVING CONDITIONS. WHEN THE VEHICLE COMES TO A COMPLETE STOP THE TORQUE CONVERTER LOCKS AND CAUSES THE VEHICLE TO LURCH FORWARD. THE PROBLEM IS NOTICEABLE IN TRAFFIC, BUT MORE OF A CONCERN WHILE PRECISION PARKING AND WHEN MOVING SLOWLY WITHOUT THROTTLE OR BRAKE BEING APPLIED. THIS HAS HAPPENED IN MY VEHICLE AND IN ALL SIMILAR LOANER VEHICLES THAT THE DEALERSHIP HAS ASSIGNED TO ME DURING SERVICE. SPECIFICALLY, WHEN PARKING THE VEHICLE AND WHEN INCHING FORWARD TO A COMPLETE STOP WITHOUT BRAKE OR THROTTLE, THE VEHICLE WILL SUDDENLY LURCH FORWARD WITHOUT WARNING AND HIT THE SIGN, ANOTHER CAR, OR CURB. THIS PROBLEM IS NOT INTERMITTENT AND HAPPENS DURING EVERY DRIVE AND STOP.

WHEN COLD, THE TRANSMISSION HAS A HARD SLIP WHEN SHIFTING BETWEEN 1ST AND 2ND GEAR. USUALLY HAPPENS IN THE MORNING WHEN I AM LEAVING MY HOUSE. ON ICY/SNOW COVERED ROAD IT WILL CAUSE THE REAR WHEELS TO LOSE TRACTION. THUS CREATING A SAFETY HAZARD FOR ME, OTHER VEHICLES OR PEDESTRIANS ON THE ROADWAY.

WHEN PUTTING VEHICLE IN DRIVE FROM PARK IT JUMPS FORWARD EVEN WITH FOOT ON THE BRAKE. WHEN GOING FROM REVERSE TO DRIVE IT FEELS LIKE THE VEHICLE IS NOT IN GEAR AND THEN ENGAGES AND THEN THE VEHICLE MAKES A CLUNK NOISE AND ABRUPTLY JUMPS FORWARD. THERE IS ALSO A ISSUE WHEN GOING FROM FIRST TO SECOND WHEN ACCELERATING AND THE SAME WHEN DOWNSHIFTING. THE TRANSMISSION ON THIS VEHICLE IS VERY ERRATIC IN NATURE, YOU NEVER KNOW WHAT IT IS GOING TO DO EVERY TIME YOU DRIVE IT. THIS HAS BEEN HAPPENING SINCE THE FIRST 100 MILES AND I NOW HAVE 8600 AND STILL HAPPENING. I HAVE TAKEN IT TO THE DEALER AND THEY STATED THEY COULD NOT GET IT TO REPEAT THE ISSUE EVEN AFTER LETTING IT SIT OUTSIDE IN 20 DEGREE WEATHER TO COOL EVERYTHING DOWN.

I WAS STOPPED ON A HILLSIDE WITH ENGINE RUNNING, SHIFT LEVER IN PARK, AND THE TRUCK STARTED TO ROLL BACKWARDS. THE TRUCK COMPUTER PUT ON THE EMERGENCY BRAKES. I TRIED THIS THREE DIFFERENT TIMES WITH THE SAME PROBLEM OF IT ROLLING BACKWARDS.

VEHICLE SHIFTS HARSHLY MAKING CONTROL QUESTIONABLE AT TIMES. I WENT TO ACCELERATE AROUND A VEHICLE LOST ALL POWER UNTIL IT FOUND A GEAR. SOMEONE WILL GET HURT BECAUSE OF THIS TRUCK ESPECIALLY ON SLIPPERY WINTER ROADS. BEEN TO THE DEALERSHIP 3 TIMES NO FIX. PLEASE HELP

THE 8 SPEED TRANSMISSION SOMETIMES GETS HUNG IN BETWEEN GEARS OR SHIFTS VERY HARD AFTER IT INTERMITTENTLY COMES OUT OF GEAR. THIS WEEK, I WENT TO CROSS A ROAD ON DRY ROAD CONDITIONS AND THE VEHICLE CAME OUT OF GEAR, THE ENGINE REVVED AND I WAS WITHOUT A GEAR FOR 2-3 SECONDS, CAUSING THE ONCOMING TRAFFIC TO BE UNCOMFORTABLY CLOSE BY THE TIME I REGAINED POWER AND WAS ABLE TO CROSS THE ROAD. THERE HAVE BEEN OTHER TIMES THAT I HAVE BEEN AT A STOP SIGN AND I GO TO TAKE OFF AND THE ENGINE REVS UP AS I HIT THE GAS BUT IT IS NOT IN GEAR AND THEN ABRUPTLY SNAPS INTO GEAR, CAUSING THE TIRES TO ACTUALLY SQUEAL. SO THIS ISSUE HAS HAPPENED WHEN THE TRUCK IS STILL MOVING AND ALSO WHEN IT WAS AT A STOP SIGN AND NOT IN MOTION,

2019 CHEVY SILVERADO, 5.3L WITH 8-SPEED TRANSMISSION. EXPERIENCED INTERMITTENT TRANSMISSION SHUDDER AT 32 - 44 MPH. VEHICLE SERVICED PER GM TS BULLETIN TO DRAIN AND FLUSH TRANSMISSION, REPLACE DEFECTIVE FLUID WITH ATF MOBILE 1 SYNTHETIC. THIS WAS DONE TWICE AND PROBLEM GOT WORSE. NOW SHUDDERS CONSTANTLY AT 32-44 MPH. DEALER WAS INFORMED BY GM TECH THAT THIS IS A NORMAL CHARACTERISTIC FOR THIS MODEL. I DISAGREE! MY BRAND NEW TRUCK WITH ONLY 5K MILES SHOULD NOT BE SHUDDERING AND SHAKING. WAS TOLD THAT THE ACTIVE FUEL MANAGEMENT SYSTEM, 2 TO 4 CYLINDER MODE IS SUSPECT AND AFFECTING TORQUE CONVERTER SHUDDER. BUT THIS IS NORMAL? I HAVE REQUESTED REPAIR OR REPLACE OR BUY BACK AND CONTACTED GM CORPORATE DIRECTLY. GM SENIOR ADVISOR TEAM HAS NOT YET CONTACTED ME. I HAVE REFUSED TO DRIVE IT, AND LEFT IT AT THE DEALERSHIP UNTIL RESOLVED. THEY GAVE ME A LOANER TO DRIVE IN THE MEANTIME. APPEARS LOTS OF INSTANCES ON THE INTERNET OF SIMILAR ISSUES AND OWNERS ARE NOT HAPPY. WHY HASN'T GM ENGINEERING FIXED THIS PROBLEM OR ISSUED A RECALL YET? I AM CURRENTLY AWAITING RESPONSES FROM GM / CHEVY FOR RESOLUTION. THIS IS UNACCEPTABLE.

WHEN SLOWING DOWN, THE VEHICLE HAS A HARD DOWNSHIFT. USUALLY IT WOULD BE DESCRIBED AS NOT BEING SMOOTH. TODAY, WHILE TRAVELING ABOUT 40 MPH WITH THE FOOT OFF THE ACCELERATOR, IT DOWNSHIFTED SO HARD IT FELT LIKE I WAS REAR ENDED BY ANOTHER VEHICLE.
