Power train

15 reports1 crash
“ON THE FREEWAY AND CAR SUDDENLY HAS OVERDRIVE LIGHT BLINKING, AT THE SAME TIME I BEGAN LOSING POWER, I WAS ABLE TO GET OFF FREEWAY BUT NOT AFTER I OPEN HOOD AND NEARLY GOT RUN OVER. I WAS CHECKING TO SEE IF THERE WAS OVERHEATING OR SMOKE. BUT NOTHING. I HAVE ALREADY REPLACED PCM, TRANSMISSION, AND TORQUE CONVERTER. CONSEQUENTLY MY SHIFTER IS BROKEN AND YOU CAN SEE DOWN INTO TRANSMISSION. OBVIOUSLY NO I CAN'T DRIVE, I WILL HAVE TO HAVE VEHICLE TOWED. WHY HASN'T TRANSMISSION BEEN RECALLED ON THIS VEHICLE. I COULD NOT THINK ABOUT IF MY CHILD WOULD HAVE BEEN WITH ME AND STOOD IN FRONT OF CAR. HE NEVER WOULD HAVE BEEN ABLE TO MOVE THAT QUICKLY OR EVEN WORSE WITH FREEWAY DRIVING I EVEN COULD HAVE BEEN HIT FROM BEHIND.”
