Chevrolet Silverado transmission problems

VEHICLE ROLLED BACK WHILE IN PARK. TRUCK WAS FOUND AGAINST THE HOUSE WITH THE DOORS LOCKED AND STILL IN PARK. EMERGENCY BRAKE IS TYPICALLY ENGAGED BECAUSE IT IS PARKED ON A SLOPE DRIVE BUT IT WAS FOUND DISENGAGED. WHILE BEING TOWED IT ALSO ROLLED WHILE LOADING ONTO THE TOW TRUCK. AGAIN, IT WAS IN PARK WITH THE EMERGENCY BRAKE ENGAGED. VEHICLE WAS LOOKED AT BY TWO SEPARATE SERVICE DEPARTMENTS WITH NO CAUSE FOUND. DAMAGE WAS DONE TO THE TRUCK AND THE HOME BUT SINCE GM COULD NOT DUPLICATE THE PROBLEM WE ARE RESPONSIBLE FOR ALL DAMAGES. WILL MOST LIKELY GET RID OF THE VEHICLE (TRADING IT IN AT SAME DEALER WHO SOLD AND SERVICED IT) BECAUSE WE DO NOT FEEL SAFE LEAVING THE VEHICLE UNATTENDED. TS

THE TRANSMISSION SLIPS WHEN EITHER STARTING FROM A COMPLETE STOP OR WHEN SHIFTING FROM 1ST TO 2ND GEARS. YOU CAN FEEL THE TRUCK THEN JERK INTO GEAR WHEN ENGAGED. NOTE: THIS IS AN AUTOMATIC TRANSMISSION AND DOES NOT DO IT ON A CONSISTENT BASIS. IT SEEMS THAT TEMPERATURE OR ROAD CONDITIONS ARE NOT A FACTOR. I HAVE TAKEN THE VEHICLE INTO A CHEVROLET DEALER 5 TIMES AND THE PROBLEM STILL PERSISTS. DT

WHEN MAKING A LEFT OR RIGHT TURN, THE STEERING WHEEL GIVES AND CAUSES TEMPORARY STEERING LOSS. TS THE VEHICLE ALSO SUSTAINED THE FOLLOWING FAILURES, THE PCV VALVE MALFUNCTIONED CAUSING THE #2 AND #3 HEAT SHIELDS IN THE TRANSMISSION TO CRACK. THIS MALFUNCTION WAS REPAIRED AND NOW THE 4 LOW GEAR IS INOPERABLE. ALSO, THE FUEL PUMP, OXYGEN SENSOR, AIR CONDITIONER COMPRESSOR AND PUMP MALFUNCTIONED. NOTICEABLY AFTER PURCHASE, THE DRIVER SIDE SEAT GIVES WHEN BRAKING. *JG

CONSUMER CALLED COMPLAINING ABOUT HAVING PROBLEM WITH TRANSMISSION WHICH IS LEAKING, DEALER REPLACED THREE TIMES THE SEAL AND STILL REOCURRING THE PROBLEM. PLEASE PROVIDE FURTHER INFORMATION. TS THE FRONT AND REAR SEALS ARE LEAKING. ALSO, THE PASSENGER SIDE SEAT BELT IS BROKEN. CONSUMER FURTHER STATES THAT THE PASSENGER SIDE SEAT BELT IS USED LESS OFTEN THAN THE DRIVER SEAT BELT AND FEELS THIS IS A FAULT WITH THE BELT ASSEMBLY. *JG

REBUILT TRANSMISSION STILL SLIPPING NOW ALSO IS GEARED WRONG AND CLUNKING WHEN SHIFTING FROM P/R/N/D WAS NOT HAPPENING BEFOR REBUILDING IT. HANDED BULLETEN STATING IT WAS NORMAL. ENGINE HAS KNOCKING AND PINGING ALL THE TIME. GM WILL NOT DO ANYTHING ABOUT IT IS NORMAL. THEY GAVE US A 100,000 MILE 6 YR WARRANTY EXCEPT THERE IS A CLAUSE THAT STATES IT DOES NOT COVER PRE EXISTING CONDITIONS AND THEY REFUSE TO SEND US SOMETHING STATING THIS IS NOT CONSIDERED A PRE EXISITING CONDITION IT'S IN OUR FILE AND SAID THEY WOULD DO NOTTHING MORE FOR ME SAID GOOD BYE AND HUNG UP. ENGINE IS ALSO LOSING GAS MILEAGE, POWER AND IS MISSING. WE ARE CONCERNED THAT IT MAY CAUSE PROBLEMS WHILE WE ARE TOWING OUR BOAT BASED ON YOUR SERVICE BULLETIN NUMBER 01058 BUILETIN SEQUENCE NUMBER 620. WE ARE CONCERENED THAT IT MAY CAUSE SERIOUS INJURY OR LOSS OF LIFE. DT
