2008 CHEVROLET SILVERADO 2500 Power Train Problems

THIS IS A 2008 CHEVY SILVERADO HD Z71 4X4 WELL TAKEN CARE OF. AND THE TRANSMISSION GOES INTO LIMP MODE ON FAST STOPS. THIS IS EXTREMELY DANGEROUS DUE TO THE FACT THAT IF A LOAD IS ON BOARD AND IT GOES INTO LIMP MODE THIS COULD BE DANGEROUS FOR ALL BEHIND THE VEHICLE AND AROUND. WHICH COULD BE A THREAT TO ALL UNEXPECTEDLY CAUSING UNDUE HARM TO OTHER WHILE IN CONTROL OF THIS VEHICLE. AND VEHICLE SENDS OUT A CODE. *TR

MY TRUCK HAS 69,755 MILES WHEN THE TRANSMISSION WENT INTO PROTECTION MODE. JERRY SMITH GARAGE OF ANACORTES WA. FOUND LOSS OF PRIME OF FLUID DUE TO POSS STICKING LUBE REGULATOR VALVE IN PUMP COVER. THIS WAS AT COST OF $5849.87 I FEEL THAT THIS TRUCK A 2500 HEAVY DUTY TRANY SHOULD LAST LONGER THAN 69,755 MILES. IT WAS BEING DRIVEN ON THE STREET

TL* THE CONTACT OWNS A 2008 CHEVROLET SILVERADO 2500. WHILE THE VEHICLE WAS PARKED IN THE DRIVEWAY, IT ROLLED BACKWARDS AND CRASHED INTO A TREE. THE CONTACT WAS CAUGHT BETWEEN THE DRIVER'S DOOR AND THE RUNNING BOARD. THE CONTACT SUSTAINED INJURIES TO THE KNEES AND DEEP LACERATIONS TO THE BODY AND HEAD, WHICH REQUIRED MEDICAL ATTENTION. A POLICE REPORT WAS FILED AND THE VEHICLE WAS TOWED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 98,000. THE VIN WAS NOT AVAILABLE.

AFTER TRUCK SITS FOR A WEEK OR MORE, ONCE STARTED AND PUT IN REVERSE IT WILL BACK OUT OF GARAGE VERY SLOWLY WHEN GIVEN FUEL EVEN AT 3000RPM. THE GARAGE SAYS TO LET IT WARM UP SHOULD NOT HAVE TO DO THIS. I THINK TRANS. FLUID OIL IS DRAINING DOWN AND HAS TO FILL BACK UP. SHOULD NOT HAVE TO DO THIS.

VEHICLE HAS BEEN STALLING AND LOSING TRAILER BRAKES. THERE IS A RECALL ON THIS BUT THIS PARTICULAR TRUCK DID NOT FALL IN THE RECALL. THE TRAILER BRAKE MODULE ON THE FRAME RAIL OF THE TRUCK WAS FULL OF WATER. I HAS BEEN REPLACED AND ALL IS GOOD NOW. COULD HAVE BEEN A VERY BAD SITUATION BUT WAS ABLE TO PREVENT AN ACCIDENT.

TRANSMISSION LINES AND OTHER AREAS ARE LEAKING BAD. THEY ARE LEAKING FROM ALL THREE HOSES AT THE FACTORY CRIMP. *TR

I HAVE REPLACED TRANSMISSION COOLER LINES TWICE (2 TIMES), SINCE PURCHASING THIS TRUCK WITH 59K MILES ON IT. BOTH TIMES WITH AC DELCO PARTS. BOTH TIMES THE TRANSMISSION COOLER LINES LEAKED, NOT AN INSTALLATION PROBLEM. 11/21/13- I FIRST NOTICED IT WHEN DRIVING AT 25 MPH PICKING UP MY KIDS FROM SCHOOL, AND I HAD TRANSMISSION FLUID SPRAYING OUT FROM UNDERNEATH MY TRUCK, CAUSING IT TO SMOKE/SMOLDER ON MY EXHAUST PIPE. (TRANSMISSION FLUID IS FLAMMABLE). THE CRIMP HAS SEPARATED FROM THE HOSE. THIS IS THE FIRST TIME I REPLACED WITH GENUINE GM PARTS. 1/16-14- 2ND TIME WAS DURING THE WINTER WHEN THE TRUCK WAS WARMING UP IN THE DRIVE WAY AND YET AGAIN THE CRIMP WAS CAUSING A LEAK, WHICH DUMPED ABOUT A GALLON OF FLUID ON MY DRIVEWAY. (AGAIN TRANSMISSION FLUID IS FLAMMABLE) I REPLACED THE LINES ONE MORE TIME AND I'M ABOUT FED UP WITH THE LACK OF HELP GM IS GIVING. THE CURRENT SET OF COOLER LINES ON THE TRUCK ARE JUST NOW STARTING TO DRIP SO ITS ONLY A MATTER OF TIME BEFORE THEY GIVE OUT AGAIN. THE TRUCK HAS VERY LOW MILES AND I METICULOUSLY MAINTAINED, THIS IS A KNOWN GM PROBLEM ON MORE THAN 1 MODEL OF VEHICLE AND I AM UNSURE WHY GM WILL NOT EXTEND A WARRANTY TO THESE FAILED PARTS. MY LOCAL GM SERVICE DEPT. HAS REFUSED TO HELP ME IN ANY WAY, EVEN THOUGH I HAVE BOUGHT GM PART EVERY TIME. WHEN WILL GM FACE THE FACTS BEFORE ONE OF THESE CATCHES FIRE AND SOMEONE DIES???? *TR

I TOOK MY TRUCK TO A REPAIR FACILITY, TO HAVE A LEAK REPAIRED, AT THE REAR OF THE TRANSFER CASE. THE MECHANIC THOUGHT THE REAR SEAL WAS LEAKING, SO HE REPAIRED THAT. ONCE THE REAR SEAL REPAIR WAS MADE, THE MECHANIC DISCOVERED THERE WAS STILL SOME LEAKING OF TRANSMISSION FLUID. UPON CLOSER INSPECTION, HE FOUND A HAIRLINE STRESS CRACK IN THE REAR SECTION OF TRANSFER CASE HOUSING. THE CRACK FIRST RAN PERPENDICULAR, THEN MADE A TURN LEFT (HORIZONTAL), TOWARD TOP OF WHERE DRIVE SHAFT ENTERS. ON SEPT. 03, 2014, A LOCAL CHEVROLET DEALER TOOK THE ORDER, FOR PART NO. 19125656CV, THEN ON SEPT. 08TH THAT SAME DEALER ADVISED THE MECHANIC WORKING ON MY TRUCK THAT THE PART WAS ON NATIONAL BACK ORDER, WITH NO ESTIMATED DATE OF WHEN IT WOULD BE AVAILABLE. I WAS ALMOST FORCED TO PURCHASE A BRAND NEW COMPLETE TRANSFER CASE ASSEMBLY, FOR OVER $1,500.00, JUST TO GET MY TRUCK BACK ON THE ROAD, AGAIN. COMMON SENSE TELLS ME, CHEVY MUST BE HAVING PROBLEMS, WITH AN AWFUL LOT OF TRUCK TRANSFER CASE REAR HOUSING SECTIONS, IN ORDER TO RUN COMPLETELY OUT OF SPARE PARTS; NATIONWIDE. I FEEL THIS LEAK COULD BE A SAFETY HAZARD, BECAUSE ONCE THE TRANSMISSION FLUID RUNS OUT, THE GEARS IN THE TRANSFER CASE WOULD PROBABLY SEIZE UP, CAUSING THE DRIVER TO LOSE CONTROL AND CRASH. I FEEL A RECALL SHOULD BE ISSUED, FOR THIS PROBLEM AND CHEVROLET SHOULD BE FORCED TO INCREASE PRODUCTION OF THE REPAIR PART NEEDED AND HAVE A SUPPLY OF THESE PARTS ON HAND (NATIONWIDE). FORTUNATELY FOR ME, MY MECHANIC WAS ABLE TO FIND THE REPAIR PART I NEEDED IN A JUNK YARD. *TR

TRANSMISSION FLUID LEAKING FROM CRIMPS WHERE METAL ENDS ARE ATTACHED TO RUBBER HOSES. *TR

Mileage: 28,537

MY TRUCK WAS DIAGNOSED AT THE DEALER WITH ALL OF THE TRANSMISSION COOLER LINES LEAKING, AT THE CRIMPS. NEARLY EVERYONE I KNOW THAT HAS A 2007-2009 HAS HAD THE SAME ISSUE. IF UNDIAGNOSED, THIS COULD LEAD TO TRANSMISSION FAILURE DUE TO FLUID LOSS, LOSS OF PRESSURE, ETC. CLEARLY A MANUFACTURING DEFECT, NO DIAGNOSIS OF CAUSE DUE TO ELEMENTS OR DRIVER ERROR, ETC. *TR

TL* THE CONTACT OWNS A 2008 CHEVROLET SILVERADO 2500. THE CONTACT STATED THAT THE TRANSMISSION WAS LEAKING FLUID AND THE VEHICLE WOULD STALL WITHOUT WARNING. THE DEALER AND THE MANUFACTURER WERE CONTACTED, BUT DENIED ANY ASSISTANCE WITH REPAIRS TO THE VEHICLE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 38,000 AND THE CURRENT MILEAGE WAS 41,000.

2008 CHEVY SILVERADO 2500, GAS ENGINE, 34,600 MILES. TRANSMISSION IS HAVING ISSUES THAT DEALER CANNOT SEEM TO FIX. NEW PUMP PUT INTO TRANNIE, STILL HAVING PROBLEMS. USUALLY HAPPENS IN TOW HAUL MODE, HAULING APPROX 5,000 LBS. TRANSMISSION WILL NOT SHIFT UP, HOLDS AND REVS TO 3500 OR 4000 RMP'S. I TAKE FOOT OFF GAS AND IT BUMPS INTO GEAR. MOST OFTEN HAPPENS AT 35MPH AND 55 MPH. WHEN SLOWING DOWN TRANSMISSION SLAMS INTO LOWER GEAR AND REVS VERY HIGH. AT 55 MPH ON I-435 IN KCMO DURING RUSH HOUR, TRUCKS TIRES LOCKED UP AND SQUEALED WHEN TRANNIE DOWN SHIFTED. HAS A MAJOR ISSUE BETWEEN 30-40 MPH. AGAIN, SLAMS BETWEEN GEARS THROWING PASSENGERS FORWARD (I DON'T WANT TO THINK ABOUT HOW IT IS AFFECTING THE HORSES!) WE ARE FIRST AND ONLY OWNER OF TRUCK. TRUCK TREATED VERY WELL, NO OFF-ROADING OR ABUSE. SAD THAT WE ARE HAVING THIS ISSUE..... IT DOESN'T EVEN HAVE 35,000 MILES ON IT!!!!! *TR

AUTOMATIC TRANSMISSION LINES 2008 CHEVY SILVERADO WITH ALLISON TRANSMISSION. FACTORY TRANSMISSION LINES LEAK AND MUST BE REPLACED. WHEN THE WEATHER TURNS COLD, THE LINES/CRIMPS HOLDING THE RUBBER HOSE TO THE PIPES FAIL AND AUTOMATIC TRANSMISSION FLUID IS LOST, SOMETIMES IN CATASTROPHIC MANNER, CAUSING THE VEHICLE TO LOOSE PROPULSION. REPORTS OF FAILURE ARE EXTREMELY COMMON, AND IT IS NOT UNUSUAL, THAT THE LINES MAY HAVE BEEN REPLACED 3 TIMES WITHIN THE 1ST 50,000 MILES. GM HAS ISSUED 'NEW, UPDATED' PARTS, BUT THEY ARE NO BETTER THAN THE ORIGINAL PARTS. THE NEW PART NUMBERS ARE 20759971, 20759972, 20759973. WILE REPAIR IS COVERED ON THE 36K BUMPER TO BUMPER WARRANTY, THERE IS NO COVERAGE ON THE 100K WARRANTY. GM SHOULD REPLACE THE LINES FREE OF CHARGE FOR THE 1ST 100K MILES WITH A HOSE THAT WILL NOT FAIL. CONSUMERS CAN TAKE THE ORIGINAL GM LINE TO A HYDRAULIC SHOP, HAVE THE RUBBER PORTION OF THE LINES REPLACED WITH STANDARD HYDRAULIC HOSE SUITABLE FOR ATF FLUID AND THERE ARE NO FURTHER FAILURES. IF CONSUMERS CAN FIX THE LINES, PERHAPS GM CAN FIND A SOLUTION. *TR
