2002 Chevrolet S10

2002 CHEVROLET S-10 LS X-CAB PICKUP MANUAL TRANSMISSION: LOUD KNOCKING NOISE COMMING FROM TRANSMISSION AND SHIFTING THROUGH GEARS IS ROUGH. WHEN CLUTCH PEDAL IS PRESSED NOISE DISAPPEARS BUT, WHEN PEDAL IS RELEASED A LOUD BANG IS HEARD FROM TRANSMISSION AND KNOCKING NOISE RETURNS. THE ROUGH SHIFTING OCCURS MOSTLY GOING INTO 3RD GEAR BUT ALSO OCCASIONALLY IN ALL OTHER GEARS. BROUGHT TO DEALER TO REPAIR FOR THE FIRST TIME ON JUN 2, 2003. TECHNICIAN SAID NOISE IS " NORMAL " FOR THIS TYPE OF VECH. DUE TO A HEAVIER DUTY TRANSMISSION. CLUTCH SLAVE UNIT WAS FOUND LEAKING, CAUSING THE ROUGH SHIFTING...DEALER REPLACED SLAVE UNIT. ON AUG. 4, 2003 TRUCK WAS ONCE AGAIN BROUGHT IN TO DEALER TO INQUIRE ABOUT KNOCKING NOISE FROM TRANS AND SHIFTING PROBLEMS (THIS TIME TRANSMISSION WOULDN'T ALLOW SHIFTER TO GO INTO 1ST GEAR AND SHIFTING WAS ROUGH AGAIN) AFTER GETTING SECOND AND THIRD OPINIONS FROM VARIOUS SHOPS, AND ALL STATING THAT KNOCKING NOISE DOES NOT SOUND "NORMAL" AND A PROBLEM WITH SHIFTING. ONCE AGAIN SERVICE TECH AT THE DEALER STATED THAT KNOCKING NOISE IS NORMAL AND FOUND NO PROBLEMS WITH SHIFTING BUT MAY HAVE FIXED A PROBLEM, BECAUSE AFTER LEAVING SERVICE DEPT, SHIFTING WENT BACK TO NORMAL BUT KNOCKING IS STILL THERE.*AK

INITIAL COMPLAINT STARTED AT APPROX 17,100 MILES. THERE WAS WATER REPORTED IN THE REAR END DIFFERENTIAL. DEALER (LUCAS CHEVROLET) REFUSED TO REPAIR UNDER WARRANTY AND TO GIVE SUGGESTIONS ON HOW WATER GOT INTO SEALED UNIT. WE PAID TO HAVE THE FLUID CHANGED AND DEALER ASSURED THAT THERE WAS NO DAMAGE TO REAR END DIFFERENTIAL. SECOND COMPLAINT WAS THAT THERE WAS A WHINING NOISE COMING FROM THE REAR END AT APPROXIMATELY 20,000 MILES. THE NOISE OCCURED BETWEEN 50 & 70 MPH AND WOULD QUIT WHEN THE GAS PEDAL WAS LET OFF. A DIFFERENT DEALER (JIM REED CHEVROLET) "REBUILT" THE REAR END DIFFERENTIAL. NOTE: DEALER WAS VERY HELPFUL IN FIXING PROBLEM. THE NEXT COMPLAINT WAS THAT AT APPROXIMATELY 23,000 MILES, AFTER THE REAR END DIFFERENTIAL FLUID WAS CHANGED, THE WHINING NOISE CAME BACK. THE DRIVING CONDITIONS WERE THE SAME AS THE SECOND COMPLAINT. THE DEALER (JIM REED CHEVROLET) AGAIN "REBUILT" THE REAR END DIFFERENTIAL. ON THE WAY HOME FROM THE DEALER (JIM REED CHEVROLET) THE REAR END IS STILL WHINING.

IN COLD WEATHER THE RUBBER BOOT ON THE MANUAL TRANSMISSION SHIFT LEVER GETS SO STIFF THAT IT WILL FORCE THE SHIFT LEVER OUT OF GEAR IF IT IS ON A DIFFERENT SIDE OF THE SHIFT PATTERN FROM WHERE IT WAS FOR THE EXTENDED PERIOD OF COLD. FOR EXAMPLE, IF IT IS PARKED IN 1ST GEAR OVERNITE IN THE COLD, IT WILL POP OUT OF 2ND OR 4TH GEAR WHILE UNDER POWER UNLESS I DRIVE WITH MY HAND ON THE SHIFT APPLYING PRESSURE TO KEEP IT IN GEAR. THIS MAKES IT DIFFICULT TO STEER AT TIMES AND IMPOSSIBLE TO ADJUST OTHER CONTROLS. DT

AT 90 DEGREES OR ABOVE THE VEHICLE WILL , AT TIMES, LOSE POWER TO THE TRANSMISSION MAKING ENTERING TRAFFIC A SAFETY HAZARD. ENGINE RPM'S ARE ADEQUATE BUT VEHICLE WILL NOT SHIFT GEARS AND ACCELERATE. DANGEROUS CONDITION WHEN ENTERING HEAFY TRAFFIC. MANUFACTURER TECHNICAL ASSISTANCE CANNOT ASSIST DEALER IN FIXING THE PROBLEM. DEALER EXPERIANCED THIS PROBLEM IN A TEST DRIVE BUT COULD NOT REPAIR AT THIS TIME.*AK
