Pinpoint Test E: Excessive Clutch Slippage

WARNING: This page is about a different car, the 2006 Mercury Montego, 2006 Ford Freestyle, and 2006 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The transmission control module (TCM) is integrated into the mechatronic assembly. If installing a new transaxle or a mechatronic assembly, the TCM will need to be checked and recalibrated (reflashed) to the latest level calibration available.
  1. E1 ELECTRONIC DIAGNOSTICS 
    • Check to make sure the transaxle harness connector is fully seated, pins are fully engaged in the connector and in good condition before proceeding.
    • Connect the scan tool.
    • With the vehicle in DRIVE and REVERSE at idle, monitor PIDs. (CLTAMP_MES) actual current for forward/reverse clutch solenoid and (CLTAMP_CMD) for commanded current forward/reverse clutch solenoid.
    • Is the current value between both PIDS no greater than 10 milliampere? 

    Yes:  GO to  E2.

    No:  INSTALL a new mechatronic assembly. REFER to MECHATRONIC ASSEMBLY . (Refer to the NOTE  preceding this pinpoint test.)

  2. E2 ELECTRONIC DIAGNOSTICS 
    • Check to make sure the transaxle harness connector is fully seated, pins are fully engaged in the connector and in good condition before proceeding.
    • Connect the scan tool.
    • With the vehicle in DRIVE and REVERSE at idle, monitor PIDs. (TR) (TSS_SRC), Pulley A (SPD_PULA) Speed.
    • The turbine shaft speed should be equal to Pulley A (primary) Speed.
    • Is the turbine speed equal to pulley A (primary) speed? 

    Yes:  GO to  E3.

    No:  REFER to DIAGNOSIS BY SYMPTOM .

  3. E3 ELECTRONIC DIAGNOSTICS 
    • Connect the scan tool.
    • With the vehicle in NEUTRAL and PARK at idle, monitor PIDs. (TR), (TSS_SRC), Pulley A (SPD_PULA) Speed.
    • The turbine shaft speed should be equal to engine speed, and pulley A (primary) speed should be at zero.
    • Is the turbine speed equal to engine speed, and pulley A (primary) speed at zero? 

    Yes:  CLEAR all DTCs. ROAD TEST to verify if concern is still present. Concern could be intermittent.

    No:  REFER to DIAGNOSIS BY SYMPTOM .
