NHTSA Complaint #10504373 — 2008 CHEVROLET SILVERADO

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
