Torque Converter Operation Test

WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The Torque Converter Clutch (TCC) will not engage if the Transmission Fluid Temperature (TFT) is below 0°C (32°F).
  1. Using the scan tool, make sure that the TFT  is within specification 43°C-47°C (109°F-117°F).
  2. Accelerate the vehicle to 35-60 km/h (22-37 mph) and maintain a consistent speed.
  3. Release the accelerator pedal to close the throttle and 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.
  4. If these actions do not occur, see Torque Converter Operations Concerns, refer to DIAGNOSIS BY SYMPTOM .
