Description:

  • The fault code indicates a low voltage condition in the gate select actuator circuit. The gate select actuator is responsible for controlling the shifting mechanism in the transmission. A low voltage condition in this circuit can affect the proper operation of the gate select actuator, potentially leading to shifting issues.

Possible Symptoms:

  • Difficulty shifting gears or failure to engage specific gears

  • Inability to shift out of a particular gear position

  • Malfunction Indicator Lamp (MIL) or Check Engine Light illuminated

  • Possible impact on the vehicle's overall drivability and transmission performance

Possible Causes:

  • Faulty gate select actuator

  • Damaged or loose wiring in the gate select actuator circuit

  • Poor electrical connection at the gate select actuator or related components

  • Faulty transmission control module (TCM)

  • Low voltage in the vehicle's electrical system

Related Parts:

  • Gate Position Actuator: The gear gate assists in gear shifting. This actuator controls how the gear is selected. If the actuator fails to select the right gear, there may be slippage or other malfunctions

Possible Solutions:

  • Inspect the gate select actuator for any signs of damage or malfunction, and replace if necessary

  • Check the wiring in the gate select actuator circuit for any damage, and repair or replace as needed

  • Ensure a proper electrical connection at the gate select actuator and related components

  • Test the voltage in the circuit to identify any low voltage issues and address them accordingly

  • If other components or systems are experiencing low voltage, diagnose and resolve the underlying electrical system issue

  • If the problem persists, consider testing and potentially replacing the transmission control module (TCM)
