NHTSA Complaint #10225030 — 2002 FORD EXPLORER

BLINKING O\D LIGHT, TRANSMISSION WILL ONLY SHIFT INTO OVERDRIVE UNDER NO LOAD, LATE AND HARD SHIFT FROM 1ST TO 2ND (OR ACCEL TO ABOUT 20 MPH THEN BACK OFF TO MINIMIZE JAR TO DRIVE LINE COMPONENTS), AND 4-WHEEL DRIVE WILL NOT ENGAGE. SAFETY ISSUES: (1) PULLING OUT IN TRAFFIC, CAN'T ACCELERATE UNTIL SHIFTS INTO 2ND GEAR (HAVE TO BACK OFF IN 1ST BEFORE IT SHIFTS) (2) 4-WHEEL TRACTION LOCK DOES NOT FUNCTION. FROM THE DAY I BOUGHT THIS EXPLORER NEW, THE TRANSMISSION SHIFTED LATER AND HARDER THAN I THOUGH APPROPRIATE. THEN AT ABOUT 80 TO 85K MILES THE OD AND 4-WHEEL DRIVE STOPPED WORKING AND SHIFTS BETWEEN 1ST TO 3RD BECAME MUCH WORSE. THE TORQUE CONVERTER LOCK UP STILL SEEMS TO BE WORKING (CAN TELL WHEN IT'S RUNNING ROAD SPEED IN 3RD GEAR). AFTER SOME RESEARCH USING FORD SHOP MANUALS, THERE SEEMS TO BE DIRECT RELATIONSHIP BETWEEN 1ST TO 2ND LATE/HARD SHIFTS AND THE OVERDRIVE PROBLEM BUT I CAN;T FIND AN OFFICIAL FORD POSTING OR TECH BULLETIN TO PROVIDE DETAILS. INTERNAL PRESSURES CONTROL THE SHIFTING AND THERE ARE SEVERAL VALVES, ORIFICES, SOLENOIDS, ETC THAT CAN CAUSE IMPROPER CONTROL PRESSURES. FORD MUST KNOW OF THE PROBLEM AND TRUTHFULLY, I THINK THE RELIABILITY OF THE TRANNY IN THE IRS EXPLORER FALLS WELL BELOW THE PUBLICS EXPECTATIONS AND SHOULD BE EVEN FARTHER BELOW FORDS ACCEPTANCE CRITERIA. DESPITE THE PREMATURE FAILURE, I WOULD PROBABLY BE CONTENT IF FORD PROVIDED THEIR EXPLORER OWNERS A DETAILED DESCRIPTION OF THE FAILURE, DEVELOPED A LONG TERM FIX, PROVIDED FORD OWNERS SOME REASONABLE OPTIONS TO INSTALL THE PARTS AND/OR MAKE THE MODIFICATIONS NEEDED FOR A LONG TERM FIX (TO INCLUDE SELF REPAIR AS AN OPTION), AND ESTABLISH A HELP DESK TO ASSIST CUSTOMERS WITH THIS EXTREMELY HIGH TRANSMISSION FAILURE RATE. *TR
