Circuit Description

The flow of transmission fluid starts in the bottom pan and is drawn through the filter, control valve body assembly, transmission case and into the oil pump assembly. The oil pump assembly pressurizes the fluid and directs it to the pressure regulator valve where it becomes the main supply of fluid to the various components and hydraulic circuits in the transmission. Hot fluid exiting the torque converter flows through the converter clutch apply valve and into the transmission cooler lines to the oil cooler located in the vehicle radiator (and auxiliary cooler if equipped). From the cooler, fluid returns to cool and lubricate the front of the transmission. In forward drive ranges, D4 fluid from the manual valve is routed through an orificed cup plug in the rear of the transmission case to feed the rear lube fluid circuit.

When the powertrain control module (PCM) detects a high transmission fluid temperature (TFT) for a long period of time, then DTC P0218 sets. DTC P0218 is a type C DTC.

Conditions for Running the DTC

No TFT sensor DTCs P0711, P0712 or P0713.

Conditions for Setting the DTC

The TFT is greater than 130°C (266°F) for 600 seconds (10 minutes).

  1. Install a Scan Tool .
  2. Turn ON the ignition, with the engine OFF.

    Important

    Before clearing the DTC, use the Scan Tool in order to record the Failure Records. Using the Clear Info function erases the Failure Records from the PCM.

  3. Record the DTC Failure Records.
  4. Clear the DTC.
  5. Inspect for correct transmission fluid level. Refer to Transmission Fluid Checking Procedure .

  1. Inspect the engine cooling system and transmission cooling system for the following conditions:
    • Air flow restrictions
    • Air flow blockage
    • Debris
  2. Inspect the transmission cooling system for damaged cooler lines.
  3. Test the oil cooler flow. Refer to Automatic Transmission Oil Cooler Flushing and Flow Test .

Perform the following procedure in order to verify the repair:

  1. Install a Scan Tool .
  2. Select DTC.
  3. Select Clear Info.
  4. Start and idle the engine until it reaches normal operating temperature.
  5. Monitor Engine Run Time and Trans. Fluid Temp. on the Scan Tool .
  6. Drive the vehicle for 10 minutes.
  7. Ensure that the transmission fluid temperature has stabilized and is less than 129°C (264°F).
  8. Select Specific DTC.
  9. Enter DTC P0218.
