Solenoid Valve Check: Notes

WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
  1. Use scan tool MB991502 to measure the transmission fluid temperature. The desired transmission fluid temperature setting for performing the solenoid valve check is 20°C (68°F).
  2. Remove the A/T control solenoid valve assembly connector.
  3. Measure the resistance between the solenoid valve terminals.
  4. The measured resistance of the solenoid valve when the transmission fluid temperature is 20°C (68°F) should match the specified resistance on the chart below.

    Specified resistance: 

    RESISTANCE SPECIFICATIONS

    TERMINAL NO. NAME RESISTANCE
    No. 7 - No. 10 Torque converter clutch solenoid valve 2.7 - 3.4 Ω [at 20°C (68°F)]
    No. 6 - No. 10 Low-reverse solenoid valve
    No. 4 - No. 9 Second solenoid valve
    No. 3 - No. 9 Underdrive solenoid valve
    No. 5 - No. 9 Overdrive solenoid valve
  5. If the solenoid valve resistance is within the specified range, check the power supply and the ground circuits.
  6. If the solenoid valve resistance is not within the specified range, drain the transmission fluid and remove the valve body cover.
  7. Disconnect the connector of any solenoid valves that are not within the specified range.

  8. Measure the resistance between terminals 1 and 2 of any solenoid valve that was not within the specified range.

    Specified resistance: 2.7 - 3.4 Ω [at 20°C (68°F)] 

  9. If the resistance is not within the specified range, replace the solenoid valve.
  10. If the resistance is within the specified range, check the wiring harness between the affected A/T control solenoid valve assembly and the solenoid valve. If a problem is not found in the above steps, check the solenoid valve O-rings and replace them if necessary.
