Pinpoint Test E: Excessive Clutch Slippage
WARNING: This page is about a different car, the 2005 Mercury Montego, 2005 Ford Freestyle, and 2005 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.
- 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 the note preceding this pinpoint test.)
- 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 .
- 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 .
