2018 Chevrolet Silverado 1500

MY VEHICLE IS HAVING HARD DOWNSHIFTING ISSUES. MAINLY FROM 2 TO 1 AND OCCASIONALLY FROM 3 TO 2. I NOTICE THERE ISNT A RECALL LISTED BUT IT DEFINITELY SEEMS LIKE A SERIOUS ISSUE. THAT COULD POSSIBLE CAUSE DAMAGE LATER ON. I'VE READ ONLINE THAT IT SEEMS TO BE A PRETTY COMMON ISSUE WITH THE SILVERADO 2014-2019. I WOULD LIKE AND EXPLANATION AND FIX PLEASE. CHEVROLET HAS CHECKED AND SAID IT DOESN'T READ AS AN ISSUE ON COMPUTER READING. THANKS

ON 8/17/2020 I STARTED GETTING A SEVERE SHAKING IN THE FRONT END OF MY 2018 CHEVROLET SILVERADO CREW CAB 4X4 LTZ. THINKING THAT I THREW JUST A WHEEL WEIGHT I TOOK IT TO MY PRIORITY CHEVROLET IN CHESAPEAKE VIRGINIA AND FOUND OUT IT HAS A SHUTTER SHAKE AS THE DEALERSHIP CALLED IT. AFTER DOING RESEARCH ON THIS I HAVE FOUND THAT THERE IS A CLASS ACTION LAW SUITE AGAINST GM ON THIS MATTER AND IS A VERY COMMON PROBLEM THAT PEOPLE ARE HAVING FROM YEARS 2014 THRU 2019. I WOULD THINK AFTER ALL THIS INFORMATION ON THIS A RECALL WOULD BE PUT OUT ON THIS.I DO NOT HAVE ANY DOCUMENTATION AT THIS TIME DUE TO IT STILL BEING AT DEALERSHIP FOR REPAIR.THIS HAPPENED WHILE DRIVING ON INTERSTATE 64 EAST BOUND AT A SPEED OF 55 UP TO 65 WHEN PROBLEM OCCURRED.

WHILE DRIVING ON INTERSTATE TOWING EMPTY 12' TRAILER, THE ENGINE STOPPED AND RECEIVED STABILITRACK MESSAGE AND TRANSMISSION TOO HOT. THIS HAPPENED AGAIN AFTER LETTING ENGINE COOL DOWN. HAD THE TRAMISSION FLUID CHANGED TWO DAYS LATER. DEALER JUST STATED THEIR WAS A LOSS OF COMMUNICATION WITH THE ENGINE. ONE WEEK LATER RECEIVED TRANSMISSION HOT, IDLE ENGINE MESSAGE ON THE INTERSTATE WHILE HAULING THE SAME TRAILER WITH ONLY A RIDING LAWNMOWER. PULLED OVER FOR 30 MINUTES AND DROVE THE REST OF THE WAY HOME AT A REDUCED SPEED. HIGHWAY SPEED WAS 70 MPH UNTIL IT OVERHEATED, THEN DROVE 50-55 MPH TO GET TO MY DESTINATION TRYING NOT TO LET TRANSMISSION TEMPERATURE OVER 220.

THE PLASTIC RADIATOR HAS CRACKED AND IS LEAKING COOLANT HEAVILY. TRUCK STILL UNDER POWERTRAIN WARRANTY BY GM IS ONLY OFFERING TO COVER 20% OF THE $1,823 REPAIR COST. I NOTICED IT WHEN STOPPED TO GET GAS, THE VEHICLE LEAKING APPROXIMATELY 1.5 GALLONS OF COOLANT WHILE STOPPED FOR APPROXIMATELY 3 MINUTES. THIS CAUSED THE VEHICLE TO OVERHEAT AND NEEDED TO ADD COOLANT JUST TO DRIVE TO SHOP. *TR

TRANSMISSION SHIFTS HARD FROM FIRST TO SECOND/SECOND BACK TO FIRST. I NOTICED THIS ABOUT A WEEK AFTER PURCHASING TRUCK. SHIFTS HARD MOSTLY IN 2WD, NOT SO MUCH IN 4WD OR HAULING/TOWING. LEAF SPRINGS AND SHACKLES HAVE SQUEAKED SINCE DAY ONE OF PURCHASE. ENGINE OIL PRESSURE IS AT 12-15PSI AT IDLE AND WILL NOT EXCEED 32-35 PSI UNDER NORMAL CONDITIONS WITH OR WITHOUT A LOAD. I'VE CHANGED THE OIL FILTER AND OIL PRESSURE SENSOR MULTIPLE TIMES. THERE ALSO SEEMS TO BE A CHIRP/TICK COMING FROM THE PASSENGER SIDE OF THE ENGINE COMPARTMENT. I'VE BEEN TRYING TO NARROW IT DOWN FOR THE LAST FEW WEEKS. SEEMS TO BE SOMETHING GOING ON IN THE ENGINE ITSELF OR POSSIBLE THE AC COMPRESSOR. TRUCK HAS 42,450 MILES
