2001 Chevrolet Redundant Silverado 2500

I HAD JUST REPLACED THE HUB AND BEARING HOUSING ON THE RIGHT FRONT AXLE ON MY FOUR WHEEL DRIVE 2001 CHEVROLET HD2500 SILVERADO PICKUP AND WAS IN THE PROCESS OF REFILLING AND BLEEDING THE AIR FROM THE BRAKE LINES. DURING THIS PROCESS IT APPEARED AS IF IT WAS REQUIRING MORE FLUID THAN I HAD REMOVED IT WAS THEN THAT I NOTICED BRAKE FLUID DRIPPING FROM THE LEFT FRONT WHEEL WELL. TO MY SURPRISE AFTER REMOVING THE PLASTIC WHEEL WELL COVER I COULDN'T BELIEVE MY EYES AT WHAT I SAW, THERE WERE THE BRAKE LINES EITHER RUSTED AWAY OR DELAMINATED. I HAVE NEVER EXPERIENCED ANYTHING LIKE THIS IN OVER FIFTY YEARS OF REPAIRING MY OWN VEHICLES, I CAN ONLY BE THANKFUL THAT I WASN'T ON THE ROAD TOWING MY FIFTH WHEEL TRAILER WHEN THE BRAKE LINES FAILED IN SUCH A CATASTROPHIC MANNER. SINCE THIS HAPPENED LATE IN OCTOBER OF 2013 I HAVE YET TO REPLACE THE BRAKE LINES, IF YOU NEED PICTURES OF THE PROBLEM I CAN PROVIDE THEM TO YOU. *TR

TL* THE CONTACT OWNS A 2001 CHEVROLET SILVERADO 2500. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 45 MPH UPHILL, THE TRANSMISSION INDEPENDENTLY SHIFTED DOWN. THE VEHICLE WOULD NOT ACCELERATE AND THEN STALLED. THE CONTACT PARKED THE VEHICLE AND PROCEEDED TO A AUTO PARTS STORE WHERE HE PURCHASED CIRCLIP AND INSTALLED IT IN THE VEHICLE. HE WAS THEN ABLE TO GET THE VEHICLE TO SHIFT INTO FIRST AND SECOND GEAR. THE DEALER WAS NOTIFIED AND THEY STATED HE WOULD NEED TO REPLACE THE TRANSMISSION OR HAVE IT REBUILT AT HIS EXPENSE. THE VEHICLE WAS NOT REPAIRED. THE VEHICLE WAS NOT DRIVEN SINCE THE INCIDENT. THE FAILURE MILEAGE WAS APPROXIMATELY 150,000.

CRANKSHAFT SENSOR DEFECTIVE. 2001 CHEVROLET 2500HD SILVERADO 8.1L VIN G VEHICLE HAS HAD A ON AND OFF PROBLEM WITH RUNNING ROUGH, ERRATIC SHIFTING, SERVICE ENGINE SOON LIGHT ON OR INTERMITTENT. TOOK TO THE DEALER BOUGHT FROM, NEVER ABLE TO FIND ANYTHING WRONG. SAID IT MIGHT BE CRANK SENSOR, BUT IF ITS RUNNING O.K. DON'T WORRY ABOUT IT. THIS PROBLEM STARTED IN APPROX FEB, 2004 AND WAS LAST AT THE DEALERS SPRING 2007. 3 DAYS IT WAS THERE AND THEY STILL COULD NOT EVEN SAY IF THERE WAS A PROBLEM. ENGINE LIGHT STILL ON. PROBLEM WITH THE ERRATIC SHIFTING, ROUGH RUNNING , ENGINE LIGHT ON CONTINUED UNTIL SEPT.2008 WHEN THE PROBLEM BECAME VERY SERIOUS. VEHICLE BEGAN TO STALL OR SIMPLY JUST QUIT RUNNING ALL TOGETHER. YOU WOULD BE DRIVING AT HIGHWAY SPEEDS OR JUST LOCAL DRIVING AND THE VEHICLE WOULD SIMPLY SHUT DOWN, LEAVING YOU WITH NO BRAKES OR STEERING. IT COULD NOT BE RESTARTED UNTIL YOU STOPPED, LET IT SIT FOR A SOMETIMES UP TO 10 MINS. VEHICLE WOULD DO THIS 2-3 TIMES A DAY, OR WEEKS BEFORE DOING IT AGAIN. IN JULY 2009 THE PROBLEM BECAME SERIOUS, WHERE THE VEHICLE WOULD JUST SHUT OF WHILE JUST SITTING AT RED LIGHTS OR STOP SIGNS. MY MECHANIC DID A SCAN AND DTC'S FOR CRANK SENSOR AND SEVERAL OTHERS CAME UP. IT WAS THOUGHT THAT EVERYTHING FROM BROKEN WIRES TO MODULES HAD TO BE CHECKED. I SUBSCRIBED TO A ONLINE VEHICLE REPAIR INFO SITE AND IMMEDIATELY FOUND A PRODUCT SAFETY RECALL #06083 12/11/2007 FOR VEHICLES WITH AN 8.1L V-8 ENGINE. THE VIN NUMBERS ON MY VEHICLE WERE HIGHER THAN THOSE IN THE RECALL, BUT THE DESCRIPTION OF THE PROBLEM FIT EXACTLY. MY MECHANIC WAS SHOWED THE INFO AND COULD NOT FIND ANYTHING ON HIS SERVICE SIGHT. IT WAS DECIDED TO CHANGE THE CRANK SENSOR. THE VEHICLES PERFORMANCE INCREASED 100% AND THE PROBLEM SEEMS TO BE RESOLVED. THE OLD CRANK SENSOR WAS SAVED. APPARENTLY G.M. HAS MANY MORE VEHICLES OUT THERE WITH BAD CRANK SENSORS THAN THEY ACKNOWLEDGE. *TR

VEHICLE IS 2001 CHEVROLET SILVERADO 2500 HD WITH 6.6L DURAMAX DIESEL AND ALLISON AUTOMATIC TRANSMISSION. AT APPROXIMATELY 88,000 MILES / APPROX 2500 HOURS, THE TRANSFER CASE HYDRAULIC PUMP WORE THROUGH THE REAR HALF OF THE TRANSFER CASE, RESULTING IN LARGE AMOUNT OF TRANSMISSION FLUID BEING RELEASED ON THE UNDERSIDE OF THE VEHICLE. SINCE THE OIL IS FLAMMABLE AND IT GETS SPRAYED ALL OVER THE BOTTOM OF THE VEHICLE (INCLUDING THE EXHAUST SYSTEM) IT PROBABLY PRESENTS A FIRE HAZARD. IT IS AT THE VERY LEAST A KNOWN DEFECT, AS MINIMAL RESEARCH ONLINE (SEE HTTP://WWW.DIESELPLACE.COM/ AND SEARCH IN THE DRIVETRAIN THREAD FOR "PUMP RUB") WILL SHOW DOZENS, IF NOT HUNDREDS OF OWNERS OF THIS VEHICLE TYPE THAT ARE HAVING TO FIX THIS PROBLEM. *TR

2001 CHEVROLET SILVERADO HAS HAD A HISTORY OF PROBLEMS. *MR THE FUEL PUMP WAS REPLACED AND WAS DIAGNOSED BY K-S FUEL INJECTION AS BEING THE CAUSE OF THE ENGINE LIGHTS AND LOW POWER, THE WAS A FUEL LEAK IN WHICH THE REAR HOUSING WAS CRACKED AND LEAKING OIL, THE TRANSFER CASE AND THE DRIVESHAFTS WERE REMOVED, THE FRONT WHEEL BEARING WAS NOISY AND WAS REPLACED, THE UPPER BALL JOINT WAS BAD, AND A FAULTY "NSDU" SWITCH WAS REPLACED. *SC
