This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with the electrical circuit that controls shifting between the 5th and 6th gears. It's like when a light switch is stuck and won't turn on the light.
The P1885 code is triggered when the transmission control module (TCM) detects a high voltage condition in the shift circuit responsible for changing gears between 5th and 6th.
The P1885 code indicates that the voltage in the 5th to 6th gear shift solenoid circuit is higher than expected. This could be due to a short circuit, faulty solenoid, or issues with the wiring or connectors.
• Transmission not shifting properly
• Check Engine Light is on
• Reduced fuel efficiency
• Faulty shift solenoid
• Wiring issues or short circuit
• Malfunctioning transmission control module (TCM)
Transmission Control Module (TCM): An electronic device that controls the transmission's functions.
Shift Solenoid: An electromechanical device that helps control the flow of transmission fluid.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the shift solenoid for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the faulty shift solenoid.
• Update or replace the transmission control module if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools (screwdrivers, wrenches)

Moderate
• Ford Explorer
• Mazda 6
• Lincoln Navigator
• Regular transmission fluid checks and changes.
• Routine inspection of transmission wiring and connectors.
• Avoid aggressive driving that can stress the transmission.
Transmission Control Issue
• Avoid driving at high speeds until the issue is fixed.
• Consult a professional mechanic for a thorough diagnosis.
Check with the vehicle manufacturer for transmission warranty coverage.
This code has been commonly reported in vehicles with high mileage or those that have not had regular transmission maintenance.
Moderate – It is advisable to address this issue soon to prevent further transmission damage.
Driving with transmission issues can be unsafe. Ensure repairs are done by a qualified professional.
• Vehicle must be driven to simulate the shift between 5th and 6th gears.
• Ensure the transmission fluid is at the correct level.
The shift solenoid is located inside the transmission, accessible by removing the transmission pan.
Q: Can I drive my car with a P1885 code?
A: It's not recommended as it can lead to further transmission damage.
Q: How can I prevent this code from appearing again?
A: Regular maintenance and inspections of the transmission system can help prevent this issue.
