This summary uses the existing diagnostic information shown in full below.
Your car has a part called a torque converter clutch that helps it change gears smoothly. This code means there's a problem with the electrical circuit that controls this part, like a wire might be broken or something isn't connected right.
The P1836 code indicates that the powertrain control module (PCM) has detected a high voltage condition in the torque converter clutch (TCC) circuit.
The torque converter clutch circuit is responsible for locking the torque converter to improve fuel efficiency and reduce engine load. A 'high' circuit condition means the voltage is higher than expected, which could be due to a short to power or a fault in the circuit wiring or connectors.
• Poor fuel economy
• Transmission slipping
• Check Engine Light illuminated
• Faulty torque converter clutch solenoid
• Short to power in the TCC circuit
• Damaged wiring or connectors
Torque Converter: A device that transfers rotating power from the engine to the transmission.
Clutch: A mechanism for connecting and disconnecting a vehicle's engine from its transmission system.
• Use an OBD-II scanner to confirm the code.
• Inspect the TCC solenoid and wiring for damage.
• Check for short circuits or open circuits in the TCC circuit.
• Replace the torque converter clutch solenoid if faulty.
• Repair or replace damaged wiring or connectors.
• Clear the code and test drive to ensure the issue is resolved.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Dodge Ram
• Regularly inspect and maintain transmission components.
• Ensure electrical connections are secure and free from corrosion.
• Follow the manufacturer's service schedule.
Transmission Circuit Issue
• Avoid driving aggressively until the issue is fixed.
• Monitor fuel efficiency for any changes.
Check with the vehicle manufacturer as transmission components may be covered under a powertrain warranty.
This code has been associated with transmission issues in vehicles with high mileage or poor maintenance history.
Moderate – It should be addressed soon to prevent further transmission damage.
Driving with a faulty torque converter clutch can lead to increased fuel consumption and potential transmission damage.
• Vehicle at operating temperature
• Steady speed on a flat road
The torque converter clutch solenoid is typically located within the transmission housing.
Q: Can I drive with a P1836 code?
A: It's possible to drive for a short period, but it's not recommended as it can lead to further 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.
