POWER TRAIN:AUTOMATIC TRANSMISSION:COOLING UNIT AND LINES
TRANSMISSION COOLER LINE LEAKING TRANSMISSION FLUID AT AN ALUMINUM CRIMP THAT CONNECTS A RUBBER HOSE TO THE TRANSMISSION COOLER; AN INFERIOR DESIGN. AS SUCH, A TRANSMISSION OIL LEAK IS A FIRE HAZARD. I AM AWARE OF TWO CAR FIRES THAT WERE CAUSED BY LEAKING TRANSMISSION COOLER LINES. THE LAST ONE INVOLVED A FORD TAURUS STATION WAGON WHERE THE OWNER HAD THE TRANSMISSION REBUILT BY HIS LOCAL TRANSMISSION SHOP (A NATIONAL FRANCHISE TRANSMISSION REPAIR SHOP) AND THEY CROSS-THREADED THE LOWER COOLER LINE AT THE TRANSMISSION. THE TRANSMISSION FLUID LEAKED ON TO THE EXHAUST CROSS-OVER PIPE AND THE CAR BURNED TO THE GROUND ON THE SIDE OF ROAD IN THE INTERSTATE. THE OWNER'S INSURANCE COMPANY SUBROGATED AGAINST THE TRANSMISSION SHOP FOR THE DAMAGES. FORTUNATELY, NO ONE GOT HURT, BUT THEY CAME CLOSE. *TR
