2004 CHEVROLET SILVERADO Power Trainautomatic Transmission Problems

TL* THE CONTACT OWNS A 2004 CHEVROLET SILVERADO. THE CONTACT STATED WHEN SHIFTING INTO DRIVE FROM A COMPLETE STOP, THE TRANSMISSION WOULD SLIP INTO NEUTRAL. THE CONTACT WOULD ATTEMPT TO ACCELERATE BUT THE VEHICLE WAS RESISTANT. WHEN REMOVING HIS FOOT FROM THE BRAKE, THE VEHICLE WOULD INDEPENDENTLY ROLL BACKWARD. THE VEHICLE WAS LEFT WITH THE DEALER WHERE THE CONTACT WAS AWAITING REPAIRS. THE FAILURE MILEAGE WAS UNKNOWN AND THE CURRENT MILEAGE WAS 27,000.

2004 CHEVROLET SILVERADO. AT ABOUT 20,000 MILES THE TRUCK STARTED TO HESITATE WHENEVER I WOULD TAKE OFF FROM A RED LIGHT, IT WOULD DO THIS ABOUT ONCE A MONTH OR SO. AT 30,000 MILES OR SO, IT WOULD KIND OF JUMP INTO GEAR WHEN FIRST TAKING OFF OR JUMP INTO REVERSE. DEALER WOULD SAY THEY TEST DRIVE AT EACH OIL CHANGE BUT COULD NOT FIND NOTHING, I WAS SURE THEY WOULDN'T BECAUSE IT DIDN'T HAPPEN EVERY TIME. NOW IT'S OCCURRING EVERY OTHER WEEK OR SO. FINALLY AT 76,000 MILES IT WOULDN'T GET PASS SECOND GEAR, DEALER FINALLY FOUND A PROBLEM AND NOW IT'S $2800 TO REPLACE PARTS. NO HEAVY CITY DRIVING, I ONLY LIVE 5 MINUTES FROM WORK. I PUT THE TRUCK ON THE HIGHWAY ONCE A MONTH TO TRAVEL ABOUT 300 MILES ROUND TRIP. THE ONLY TIME THE DEALER WROTE ANYTHING DOWN, I DISCOVERED, WAS AFTER THE WARRANTY EXPIRED....

1. NOTICED TRANSMISSION SLIPPING OVER THE LAST FEW MONTHS 2. A FEW WEEKS AGO, THE TAIL LIGHT, RIGHT TURN SIGNAL AND CRUISE CONTROL AND DASH LIGHTS STARTED MALFUNCTIONING 3. RECENTLY, THE PAINT AROUND REAR PASSENGER DOOR AND ROOF IS PEELING. *NM

DT*: THE CONTACT STATED WHILE IN MOTION THE TRANSMISSION SLIPPED AND JERKED INTERMITTENTLY. THE VEHICLE WAS TAKEN TO THE LOCAL DEALERSHIP FOR INSPECTION. THE DEALER GREASED THE DRIVESHAFT WITH HI-TEMPERATURE GREASE ON THE SPLEEN. AT 2000 MILES LATER, WHILE DRIVING AT 70 MPH, THE DRIVESHAFT SHEARED, BROKE AWAY FROM THE TRANSMISSION AND REAR END. THE CONTACT LOST CONTROL OF THE VEHICLE. HOWEVER THE VEHICLE WAS ABLE TO BE PULLED ONTO THE EMERGENCY LANE. THE VEHICLE WAS TOWED TO THE LOCAL DEALERSHIP WHERE THE DEALER REPLACED THE DRIVESHAFT AND TRANSMISSION. *AK

FAILURE OF THE NEUTRAL POSITION SAFETY SWITCH, 2004 CHEV SILVERADO DIESEL WITH ALLISON TRANSMISSION. THE SAFETY SWITCH SHORTS OUT AND FAILS DUE TO WET DRIVING CONDITIONS. THIS FAILURE RESULTS IN THE TRANSMISSION GOING INTO A "FAIL SAFE" CONDITION THAT DOES NOT ALLOW THE TRANSMISSION TO SHIFT, STRANDING THE VEHICLE. CHEVROLET HAS REDESIGNED THE PART NOW 3 TIMES, BUT WILL NOT WARRANTY OR STAND BEHIND THEIR PRODUCT. THIS SWITCH HAS FAILED ON ME TWICE DURING SNOW CONDITIONS. *NM

WHEN VEHICLE HAS BEEN DRIVEN FOR LESS THAN 2-3 MILES AND WHEN TRANSMISSION IS COLD THE FOLLOWING OCCURS: WHEN THE VEHICLE OPERATOR STOPS AT AN INTERSECTION, STOP SIGN, OR STREET CORNER - THE ENGINE AND TRANSMISSION CONTINUES TO PROPEL THE VEHICLE FORWARD WHILE THE BRAKES ARE APPLIED. THE RESULT IS THAT THE BRAKES ARE FIGHTING AGAINST THE ENGINE. THE VEHICLE OPERATOR MUST PUT THE VEHICLE IN NEUTRAL TO STOP THE VEHICLE. IN MANY CASES, THE VEHICLE TRAVELS WELL INTO THE INTERSECTION OR WELL PAST THE NORMAL STOPPING POINT BEFORE IT FINALLY COMES TO A HALT. THE RESULT HAS BEEN SEVERAL NEAR COLLIISIONS WITH CROSS TRAFFIC. THE DEALER HAS BEEN CONSULTED, BUT THE RESPONSE HAS BEEN: "UNABLE TO DUPLICATE THE PROBLEM - ALL SYSTEMS OPERATING CORRECTLY" "THIS IS NOT TRUE!! THIS VEHICLE HAS ONLY 16,000 MILES AND IS 18 MOS OLD - BUT THIS HAS OCCURRED NEARLY 10 TIMES. THE MOST...

DT: 2004 CHEVROLET SILVERADO. THE CONSUMER STATES THAT THE TRANSMISSION HAS A SLIP IN IT AND IT STALLS. THE DEALERSHIP INSISTS THERE IS NOTHING WRONG WITH THE VEHICLE AND IT CANNOT BE FIXED. THE VEHICLE HESITATES AND THEN CLANGS WHEN IT CATCHES INTO GEAR. THE MANUFACTURER STATED THEY NEED TO SPEAK WITH THE DEALERSHIP BEFORE THEY COULD MAKE A DECISION. THE PROBLEM HAS BEEN OCCURRING SINCE APPROXIMATELY FEBRUARY 2005. THIS DOES NOT HAPPEN ALL OF THE TIME. *AK

THE PROBLEM STARTED APPROXIMATELY A MONTHS AFTER PURCHASING THE VEHICLE. HAS NOT HIT ANYTHING YET, BUT HAS COME CLOSE ON SEVERAL OCCASIONS.

DT: WHILE DRIVING, THE CONSUMER FOUND HE WAS UNABLE TO GET THE ENGINE OUT OF 3RD GEAR AS THOUGH IT NEEDED TO BE GEARED DOWN. THE VEHICLE IS AN AUTOMATIC AND THOUGHT IT WAS AN ISOLATED INCIDENT.
