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.

ON A PRIOR DATE THE GAS PEDAL STUCK AND WOULD NOT MOVE, CAR JUST IDLED IN A PARKING LOT FOR ABOUT FIVE MINUTES. THIS WASN'T FIRST TIME IT STUCK, BUT PRIOR TIMES IT ALWAYS RELEASED RIGHT AWAY. *TR

THEN THE CAR DIED AND I HAD TO WAIT A FEW MINUTES TO TURN IT BACK ON. 2ND INCIDENT- I WAS DRIVING ON A BUSY ROAD DURING RUSH HOUR AND TRIED TO STOP AT A STOP LIGHT BUT THE CAR ACCELERATED SO I HAD TO KEEP BREAKING BUT THE CAR WOULD NOT STOP ACCELERATING SO I TURNED THE CAR OFF. WHEN I TRIED TO TURN THE CAR BACK ON, NOTHING WORKED (HAD NO POWER AT ALL THEREFORE I COULD NOT TURN ON MY HAZARDS TO SIGNAL TO PEOPLE THAT MY CAR WAS STALLED). I WAITED THEN TRIED TO TURN IT ON AGAIN AND IT TURNED ON BUT WAS STILL ACCELERATING ONLY I WAS IN PARK SO IT DID NOT GO ANYWHERE. I TURNED THE ENGINE OFF BUT DID NOT TURN THE CAR OFF SO I COULD TURN HAZARDS ON. I WAITED SEVERAL MINUTES THEN TRIED AGAIN AND WAS ABLE TO PULL OFF THE ROAD. *TR

15V606000 · Power Train:automatic Transmission:gear Position Indication (prndl); Power Train:automatic Transmission:lever And Linkage:floor Shift

Sep 29, 2015

Ford Motor Company (Ford) is recalling certain model year 2001-2008 Ford Escape and Mercury Mariner vehicles manufactured March 31, 2001, to September 1, 2009. The affected vehicles are equipped with either a 2.3L or 3.0L engine and have had their CD4E transmission replaced with remanufactured one that was rebuilt between June 11, 2015 through July 15, 2015. These service repair part transmissions have a shift lever bolt that may not be properly tightened. As a result, the shift control lever could disengage from the transmission without warning.

Consequence & remedy

Consequence: If the shift lever disengages from the transmission, a driver may be unable to shift gear positions and the indicated shift position may not represent the gear position the vehicle is in. Should a disengagement occur while the vehicle is being driven, when the driver goes to stop and park the vehicle, the gear selection indicator may show that the transmission is in the "PARK" position, but the vehicle transmission may not actually be in the "PARK" gear position. If the vehicle is not in the "PARK" position there is a risk the vehicle will roll away as the driver and other occupants exit the vehicle or anytime thereafter. A vehicle rollaway increases the risk of injury to exiting occupants and bystanders.

Remedy: Ford will notify owners, and dealers will inspect the transmissions and either tighten the manual shift lever bolt or replace the manual shift lever assembly. These repairs will be performed free of charge. The recall began on October 23, 2015. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 15S28.
