This summary uses the existing diagnostic information shown in full below.
This code means that a part in your car's transmission, called a solenoid, is getting too much electricity. It's like when you turn on a light switch and the light bulb gets too much power and might burn out.
The P2739 code is triggered when the transmission control module (TCM) detects a high voltage condition in the pressure control solenoid F circuit.
The pressure control solenoids are responsible for regulating the hydraulic pressure in the transmission. The TCM monitors the voltage and current levels in the solenoid circuits. If it detects a voltage level that is higher than expected, it sets the P2739 code. This can be due to electrical issues such as a short circuit or a fault in the solenoid itself.
• Harsh or erratic shifting
• Transmission slipping
• Illuminated check engine light
• Faulty pressure control solenoid F
• Short circuit in the solenoid wiring
• Faulty transmission control module (TCM)
Solenoid: An electromechanical device that converts electrical energy into mechanical movement.
TCM: Transmission Control Module, a computer that controls the transmission.
• Scan the vehicle for codes and freeze frame data.
• Inspect the wiring and connectors for damage or corrosion.
• Test the solenoid for proper resistance and operation.
• Replace the faulty pressure control solenoid.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the transmission control module if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Camry
• Honda Accord
• Ford F-150
• Regular transmission fluid changes
• Routine inspection of wiring and connectors
• Avoiding overloading the vehicle
Transmission Control
• Have your transmission inspected by a professional.
• Avoid driving the vehicle aggressively until repaired.
Repairs may be covered under the powertrain warranty if the vehicle is still within the warranty period.
This code has been associated with transmission issues in vehicles with electronic control systems, particularly in models from the early 2000s onwards.
Moderate – It is advisable to address this issue soon to prevent further transmission damage.
Driving with a faulty transmission can be unsafe and may lead to further vehicle damage.
• Vehicle at operating temperature
• Transmission in drive
The pressure control solenoid is located inside the transmission, usually attached to the valve body.
Q: Can I drive with a P2739 code?
A: It's not recommended to drive for long periods with this code as it can cause further damage to the transmission.
Q: How can I reset the P2739 code?
A: You can reset the code using an OBD-II scanner, but it's important to fix the underlying issue first.
