Ford Taurus Service Manual: General Procedures

Solenoid Body Identification Procedure

Original Solenoid Body Service Tag

  1. Using the scan tool, select Powertrain, Transmission and Transmission Solenoid Body Identification from the toolbox icon and follow the instructions displayed on the scan tool.
    The solenoid body identification screen displays solenoid body identification information:
    • Solenoid body identification is a 7-digit number
    • Solenoid body strategy is a 13-digit number
      The next screen displays the current solenoid body identification and strategy data file stored in the PCM. If the solenoid body strategy field is blank, the module contains a partial transmission solenoid body strategy. This is due to a corrupt or missing file at the time the programmable parameters were completed.
  1. NOTE: The 13-digit solenoid body strategy number consists of only numbers. Letters are not used.

    Compare the solenoid body identification and strategy (if available) to the solenoid body original service tag located on top of the transmission case.

Replacement Solenoid Body Service Tag

  1. If the solenoid body identification and strategy on the scan tool match the solenoid body service tag or replacement tag, then the solenoid body identification and strategy are correct for this transmission and a solenoid body strategy download is not required. If the solenoid body service tag or replacement tag is missing or damaged so its not readable or does not match the identification or strategy on the scan tool, remove the solenoid body connector and view the solenoid body identification and strategy printed on the solenoid body connector. If its not readable, remove the main control cover, REFER to Main Control Cover. The 7-digit identification number and the 13-digit strategy number are stamped on the solenoid body.

  1. NOTICE: If the solenoid body information does not match the module information, transmission damage or driveability concerns can occur.

    Inspect the solenoid body identification and strategy printed on the solenoid body connector and compare this to the solenoid body service tag on the transmission case. If the solenoid body identification and strategy printed on the solenoid body connector does not match the solenoid body service tag or if the solenoid body identification and strategy printed on the solenoid body connector match the solenoid body service tag on the transmission case but do not match the solenoid body identification and strategy numbers displayed on the scan tool, a solenoid body strategy data download is required.

Solenoid Body Strategy Download

  1. Using the scan tool, select module Programming and Programmable Parameters under the toolbox icon and select transmission. Follow the instructions displayed on the scan tool.
    There are fields to enter the solenoid body 7-digit identification and 13-digit strategy recorded from the solenoid body.
  1. NOTICE: If the solenoid body information is not correct, transmission damage or driveability concerns can occur.

    Enter the solenoid body identification and strategy.
    The scan tool verifies the numbers entered are valid and display a message if the information is not valid.
    The scan tool will check to verify the file is present on the scan tool. If the file is present, the technician may proceed with downloading the file to the PCM. If the file is not present, the scan tool will need to be connected to the PTS server to download the file onto the scan tool.

  1. Verify the file is present on the scan tool. If the file is present, go to Step 8. If the file is not present, continue with this procedure.
  1. Connect the scan tool to the PTS server.
    The screen will display a progress bar when connecting to the network.
  1. Follow the instructions on the network to download the strategy file to the scan tool.
    The screen will display a progress bar when downloading the strategy file to the scan tool and display a message if it is downloaded successfully.
  1. If the scan tool cannot connect to the PTS server, download the file from www.motorcraft.com.
    If the scan tool cannot download a strategy from the web site, a partial strategy will automatically be downloaded.
  1. Reconnect the scan tool to the vehicle.
  1. Follow the instructions displayed on the scan tool.
  1. If a new solenoid body was installed, compare the 7-digit identification and the 13-digit strategy fields from the solenoid body to the replacement solenoid body tag provided with the solenoid body service kit and place it over the existing identification tag.
    The scan tool will automatically download the strategy file or partial strategy file to the PCM and will display a progress bar while downloading. The scan tool will display a message when it is finished downloading the data that states that the file was downloaded successfully.

  1. NOTICE: If a drive cycle is not completed, erratic shifts and driveability concerns may occur.

    Test drive the vehicle. Refer to Solenoid Body Strategy Drive Cycle in this section.

Solenoid Body Strategy Drive Cycle

NOTE: Always drive the vehicle in a safe manner according to driving conditions and obey all traffic laws.

NOTE: The engine and transmission must be at normal operating temperature.

  1. Bring the transmission to normal operating temperature.
  1. With the engine running and the brake applied, move the selector lever through the gears in the following order, pausing in each gear for 4 seconds: N, R, N, D, R, D, N. Repeat this pattern 2 times. If any engagements feel soft or harsh, repeat this procedure.
  1. Drive the vehicle and accelerate at a moderate throttle so that the upshifts occur at 2,000 rpm up to 80 km/h (50 mph) and brake moderately to a stop. Repeat this pattern 2 times.
  1. Drive the vehicle and accelerate at a moderate throttle so the upshifts occur at 3,000 rpm up to 80 km/h (50 mph) and brake moderately to a stop. Repeat this pattern 2 times.
  1. With the engine running and the brake applied, move the selector lever through the gears in the following order, pausing in each gear for 4 seconds: N, R, N, D, R, D, N. Repeat this pattern 2 times.
  1. From a stop, accelerate to 40 km/h (25 mph), then release the throttle. Keep the throttle closed and pull the selector lever into the "L" position and allow the vehicle to coast down to 16 km/h (10 mph). Repeat this pattern 2 times.

Transmission Fluid Level Check

Material

  1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Section 100-02.

    Ford Taurus. Automatic Transmission

  1. Start the engine and move the selector lever slowly through each gear, stopping in each position and allowing the transmission to engage.
  1. With the engine running in PARK on a level hoist make sure the transmission is at normal operating temperature 85-93º C (185-200º F). Check the transmission fluid is even with the oil leveling plug hole.
