DIAGNOSTIC PROCEDURE

If there is a service concern involving one of the orange “Service tagged transmissions” call the toll-free number between the hours of 8:00AM and 4:30PM EST Monday through Friday (a recorder is on 24 hours per day), after conducting the following diagnostic procedure.

Use the following procedure when servicing the orange tagged transmissions:

  1. Check and record the transmission fluid level.
    1. If low, fill with Motorcraft MERCONŽV Automatic Transmission Fluid (XT-5-QM) (new fluid for 1998 4R70W transmissions) to the proper level and check for a leak.
    2. If a leak is the only concern, call the toll-free number prior to the repair.
  2. Check the vehicle harness connectors for proper installation at the Transmission Range (TR) sensor, Output Shaft Speed (OSS) sensor, Vehicle Speed Sensor (VSS) and transmission connector.
  3. Perform EEC system Quick Test and record all codes.
  4. If no fault codes are present, go to Step 5. If fault codes are present, perform the required pinpoint tests as directed in the 1998 Powertrain Control/Emissions Diagnosis (PC/ED) Service Manual for any fault codes received. Repair all NON-transmission codes and verify if transmission symptom still exists.
  5. If the transmission symptom exists, install Rotunda New Generation Star (NGS) Tester and follow the appropriate output state control instructions to determine if the concern is internal to the transmission.
  6. If the transmission requires service, call Ford Motor Company toll-free at (800) 551-0692 (all U.S. and Canadian dealers only).

    NOTE:DO NOT DISASSEMBLE ANY TRANSMISSION PRIOR TO CALLING THIS TOLL-FREE NUMBER.

    All diagnostic information (fluid level, EEC codes, transmission test results with NGS, transmission concern, and transmission tag information) must be recorded before calling Ford Motor Company.
