Special Tool(s)

WARNING: This page is about a different car, the 2011 Lincoln MKZ and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

SPECIAL TOOL(S)

Vehicle Communication Module (VCM) and Integrated Diagnostic System (IDS) software with appropriate hardware, or equivalent scan tool

Prior to torque converter installation, all diagnostic procedures must be followed. This is to prevent the unnecessary installation of new or remanufactured torque converters. Only after a complete diagnostic evaluation can the decision be made to install a new or remanufactured torque converter.

Begin with the normal diagnostic procedures as follows:

Preliminary Inspection
Know and Understand the Customer Concern
Verify the Concern - carry out the torque converter operation test
Carry out Diagnostic Procedures:

Retrieve and record all DTCs. Refer to DIAGNOSTICS in this service information.

Repair all non-transaxle related DTCs first.
Repair all transaxle DTCs.
Carry out Pressure Test. Refer to SPECIAL TESTING PROCEDURES in this service information.
Carry out Stall Speed Test. Refer to SPECIAL TESTING PROCEDURES in this service information.
Carry out diagnostic routines. Refer to DIAGNOSIS BY SYMPTOM in this service information.
Use the index to locate the appropriate routine that best describes the symptom(s). The routine will list all possible components that may cause or contribute to the symptom. Check each component listed, diagnose and repair as required, before repairing the torque converter.

Torque Converter Operation Test

NOTE: The Torque Converter Clutch (TCC) will not engage if the Transmission Fluid Temperature (TFT) is below 0°C (32°F).

Using the scan tool, make sure the TFT is within specification 43°C-47°C (109°F-117°F).
Accelerate the vehicle to 35-60 km/h (22-37 mph) and maintain a consistent speed.
Release the accelerator pedal to close the throttle then press the accelerator to partially open the throttle while monitoring the scan tool engine speed and TCCAMP_MES. The PID will read 0 when the TCC is released, and 1 when the TCC is applied. The engine speed will increase when the TCC is released and decrease when the TCC is applied.
If these actions do not occur, see Torque Converter Operations Concerns, refer to DIAGNOSIS BY SYMPTOM in this service information.
