2016 GMC Sierra 1500 Power Train

TRUCK LURCHED UNCONTROLLED FOR SEVERAL FEET WHEN PLACED IN REVERSE GEAR.

THE TRUCK HAS A HORRIBLE VIBRATION FROM AROUND 45 MPH AND UP. HAVE TEST DROVE OTHER 2016 GMC SIERRAS WITH SAME ISSUE. HAVE TAKEN IT BACK TO THE DODGE DEALERSHIP WE BOUGHT IT FROM AND THEY SAID IT SHOULD BE A RECALL

TRUCK SHIFTS REALLY HARD AND IS UNPREDICTABLE. I ALMOST DROVE THROUGH MY GARAGE DOOR THE OTHER DAY SHIFTING TO DRIVE FROM REVERSE. TRUCK WILL LUNGE FORWARD OR DELAY IN SHIFTING. THERE HAVE BEEN A FEW TIMES I'VE HAD TO SLAM ON THE BRAKES BEFORE I BACKED INTO SOMETHING. I HAVE BROUGHT IT IN 3-4 TIMES FOR THE ISSUE AND GMC WON'T REMEDY THE PROBLEM.

THIS ISSUE STARTED A FEW MONTHS AFTER I PURCHASED THE TRUCK TOOK IT TO TWO DEALERS THEY SAY ITS NORMAL. CALLED GMC & THEY HAVE NO RECALL. WHEN DRIVING THE TRUCK & HAVE TO SLOW DOWN IN TRAFFIC THE AUTOMATIC TRANSMISSION DOWN SHIFTS & HAS A VERY NOTICABLE JERK. WILL ACTUALLY JERK THE HOLE TRUCK. PEOPLE WHO HAVE RODE WITH ME TELL ME I HAVE A TRANSMISSION PROBLEM. WHAT CAN I DO
