Torque Converter Operation Test

WARNING: This page is about a different variant/trim than selected.
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 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 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.
  4. If these actions do not occur, see TORQUE CONVERTER OPERATIONS CONCERNS , refer to DIAGNOSIS BY SYMPTOM  .
