Shift Point Road Test

WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
Special Tool (s)

GFD134414Courtesy of FORD MOTOR COMPANY
 Vehicle Communication Module (VCM) and Integrated Diagnostic System (IDS) software with appropriate hardware, or equivalent scan tool
NOTE: Always drive the vehicle in a safe manner according to driving conditions and obey all traffic laws.

This test verifies the shift control system is operating correctly.

  1. 1.

    Bring engine and transmission up to normal operating temperature.

  1. 2.

    Operate vehicle with the selector lever in the D position.

  1. 3.

    Apply minimum throttle and observe speeds when an upshift occurs. Refer to the Shift Speeds chart in this article.

  1. 4.

    With the selector lever in the D position and speed above 80 km/h (50 mph) and less than half throttle, move the selector lever from the D position to manual 2 position and release the accelerator pedal. The transmission should downshift into 2nd gear. With the transmission remaining in the manual 2 position, move the selector lever into the manual 1 position and release the accelerator pedal. The transmission should downshift into 1st gear at speeds below approximately 45-56 km/h (28-35 mph).

  1. 5.

    If the transmission fails to upshift/downshift, refer to Diagnosis By Symptom .

Road Test - Adaptive Drive Cycle 

NOTE: Always drive the vehicle in a safe manner according to driving conditions and obey all traffic laws.

  1. 1.

    Connect the scan tool to the DLC.

  1. 2.

    NOTE: Disconnecting the battery does not clear the KAM.
    NOTE: Do not clear the PCM KAM.

    Using the scan tool, clear the adaptive table before conducting an adaptive drive cycle test.

  1. 3.

    Verify the transmission fluid is at normal operating temperature, between 96.7 °C-102 °C (206 °F-215 °F). If the transmission fluid is not at operating temperature, drive the vehicle until the operating temperature is reached.

  1. 4.

    NOTE: The transmission fluid must be at operating temperature before proceeding to this step.

    Drive the vehicle on a level road surface performing the adaptive drive cycle.

    1. 1.

      Accelerate from a stop with light throttle to 24 km/h (15 mph) then release the accelerator pedal.

    1. 2.

      Gently brake and bring the vehicle to a stop and hold the brake for 6 seconds.

    1. 3.

      Repeat substeps 1 and 2 an additional 5 times.

    1. 4.

      Accelerate from a stop with light throttle so the 1-2, 2-3 and 3-4 shifts occur with engine rpm between 1, 700-2, 000.

    1. 5.

      Continue accelerating until the vehicle speed reaches 80 km/h (50 mph) or the 5-6 upshift is reached.

    1. 6.

      Gently brake and bring the vehicle to a stop and hold the brake for 10 seconds.

    1. 7.

      Repeat substeps 4, 5 and 6 an additional 3 times.
