    • Check for any shorted, damaged, or corroded wires and connectors leading to the Gear 6 solenoid. Repair or replace as necessary.
  • Test Solenoid:
    • Test the Gear 6 solenoid to ensure it is functioning correctly. Replace the solenoid if it is found to be defective.
  • Measure Current:
    • Use a multimeter to measure the current at the solenoid. Ensure the current is within the specified range.
  • Consult Technical Support:
    • If the issue persists after performing the above checks, consult technical support or the manufacturer for further assistance.


Regular inspection and maintenance of the electrical system can help prevent solenoid-related issues and ensure reliable operation of the transmission.
