2003 CHEVROLET AVALANCHE Power Trainautomatic Transmission Problems

PICK A PROBLEM. PIN FROM TRANSMISSION GEARS WERE TOO SHORT FROM THE MANUFACTURER, CAUSING THE TRANSMISSION TO NOT SHIFT PROPERLY. THIS REPAIR WAS DONE AT 8000 MILES. 4 QUARTS. LOW ON OIL WITHIN MONTH OF CHANGING. NO LEAKS AND NO EXPLANATION FROM THE DEALER AS TO WHERE THE OIL WENT. A/C FUNCTIONED IMPROPERLY AFTER TRUCK SURGED AT TRAFFIC LIGHT. STILL NO EXPLANATION. REMOTE ENTRY WORKS WHEN IT WANTS TO. INTERIOR LIGHTS PULSE WHEN TRUCK IDILING. HEATER MOTOR FUNCTIONS ACCORDING TO SPEED OF VEHICLE, SLOW WHEN BRAKING AND SPEEDS UP WHEN ACCELERATING. DRIVERS POWER WINDOW STOPPED FUNCTIONING AND STARTED WORKING THE EVENING BEFORE TAKING IT TO THE DEALERSHIP FOR REPAIR. POPPING NOISE FROM EXHAUST JUST AFTER STARTING AND SHUTTING OFF. FROM INSIDE THE VEHICLE WHILE RUNNING I CONTINUOUSLY HEAR COOLING FLUIDS FLOWING. SOMETIMES THE HORN DOES NOT FUNCTION WHILE THE VEHICLE IS TURNED OFF. BRAKING HAS ALWAYS BEEN A PROBLEM FROM...

2003 CHEVROLET AVALANCHE WITH HARSH AND SUDEN UNEXPECTED DOWN SHIFTS. DEALER HAS ATTEMPED REPAIR SEVERAL TIMES WITHOUT REPAIRING THE PROBLEM. WHEN SLOWING IN TRAFFIC OR FOR A TURN THE TRANSMISSION WILL DOWNSHIFT HARD AND CLUNK AND BANG AS IF SOMETHING IS GOING TO BREAK. THIS IN MY OPINION IS A SAFETY HAZARD ON SLIPPERY ROADS WHILE MAKING A TURN AS IT COULD CAUSE A SPINOUT. LAST CALL FROM DEALER THE SERVICE MANAGER READ TO ME A TSB FROM CHEVROLET SAYING THIS WAS A NORMAL CONDITION AND NOT TO ATTEMPT A REPAIR. NOT ACCEPTABLE. I HAVE BEEN AN AUTO TECH FOR 38 YEARS. I FEEL THE TRANSMISSION IS SHIFTING INTO 1ST GEAR INSTEAD OF 2ND WHEN SPEED DROPS JUST BELOW 20MPH. THIS JUST MAY BE A SHIFT PROGRAM PROBLEM, BUT WHAT DAMAGE IS BEING DONE TO TRANSMISSION OVER LONG TERM? *AK

TRANSMISSION STARTED MAKING GROWLING AND WHINING NOISE WHILE ATTEMPING TO SHIFT INTO 4TH GEAR, THEN STARTED SLIPPING IN 4TH GEAR.SHIFTING WAS ALSO STIFF OR HARSHER THAN WAS NORMAL FOR THE VEHICLE PRIOR TO THIS. I TOOK TO DEALER AND WAS DISMISSED AS THEIR COMPUTER DID NOT RECORD ANY TROUBLE CODES. 1 WEEK LATER, AND ONLY 65 MILES TRAVEL DISTANCE, BOTH 2ND AND 4TH GEARS COMPLETELY FAILED, CAUSING A COMPLETE OVERHAUL AND REBUILD OF TRANSMISSION. VEHICLE HAD ONLY 14, 700 MILES ON IT WHEN PROBLEM SURFACED. DEALERSHIP TOLD ME NO KNOWN PROBLEMS ASSOCIATED WITH THIS MODEL VEHICLE.*AK

THE TRUCK CONTINUED TO SHAKE WHEN DEPRESSING THE GAS PEDAL. TURNS OUT THE TRANSMISSION WAS MESSED UP. THE DEALER FOUND LOTS OF METAL IN THE PAN. REBUIT THE BROKEN PARTS @ 15,000 MILES NOT A NEW ONE JUST REBUILT. *AK

ON DECEMBER 12, 2003 VEHICLE STALLED IN THE MIDDLE OF AN INTERSECTION, RESULTING IN A CRASH THAT COULD HAVE BEEN FATAL. CONSUMER STATED, THIS VEHICLE HAD BEEN SEVEN TO EIGHT TIMES AT DEALER WITH ENGINE AND TRANSMISSION PROBLEMS. DEALER COULD NOT DUPLICATE OR CORRECT THE PROBLEM.*AK
