P2739 code definition

The P2739 code is stored when the PCM detects an abnormality with a specific solenoid circuit or pressure control solenoid.

What the P2739 code means

The computer-controlled automatic transmission in your vehicle applies varying degrees of hydraulic pressure to provide torque converter lockup and shift actuation. Pressure is regulated through at least one electronic pressure control solenoid which is controlled by the PCM.

Although the actual parameters of the code will differ across manufacturers and models, almost every application relies on calculations based on engine load, throttle position, vehicle speed and engine speed in order to determine the desired degree of pump pressure necessary for the most efficient operation.

If the appropriate amount of fluid pressure doesn’t coincide with the actual amount that is detected, the code will be stored. Some applications will only turn on the Check Engine Light after multiple failure cycles.

What causes the P2739 code?

Many reasons could lead to the P2739 code being triggered in your vehicle:

  • An electronic pressure control solenoid malfunctioning

  • Hydraulic blockages occurring inside the internal transmission fluid passages

  • Low transmission fluid

  • Transmission fluid that has been contaminated or is otherwise dirty

  • Mechanical failures within the transmission

What are the symptoms of the P2739 code?

Unfortunately, sometimes, there are no detectable symptoms related to the P2739 code, despite the fact that your vehicle isn’t performing correctly. Other times, you’ll notice something is wrong right away because you won’t be able to shift. The torque converter clutch may also refuse to engage or disengage.

Another common symptom is that your vehicle will go into “limp-in” mode. The PCM will activate this mode because it ensures your engine can only operate at minimal RPMs, keeping the temperature down and preventing further damage.

Your transmission may slip or become overheated. Shifting may become quite difficult. Fuel efficiency will most likely suffer.

This code is often associated with gear ratio, lock up, shift solenoid, converter clutch and transmission slippage codes.

How does a mechanic diagnose the P2739 code?

Your mechanic will use a scanner to diagnose this code along with a digital ohmmeter. They’ll then go on to examine the transmission and possibly the transmission pan by removing it.

Depending on the extent of the problem, they may also need to check on the wiring and connectors. Once this part of the diagnosis is done and the codes are cleared, the mechanic will test drive the vehicle to see if they reappear.

Common mistakes when diagnosing the P2739 code

High-pressure pumps are often replaced in error because many mechanics will overlook the wiring malfunctions and/or electronic pressure control solenoid that may be responsible for the problem.

How serious is the P2739 code?

You never want your transmission to overheat which is a possibility if the problems behind the P2739 code continue to go overlooked. At the very least, this will most likely be an expensive repair because of the damage that occurs when transmissions overheat.

Although the other symptoms listed above are definitely not dangerous, they are certainly extremely dangerous. “Limp-in” mode, for example, will make your vehicle all but useless.

Harsh shifting and decreased fuel efficiency could also end up costing you quite a lot of money.

What repairs can fix the P2739 code?

  • Transmission fluid may be replaced

  • Replacement of the transmission and torque converter if overheating occurred

  • Replacing/repairing burned or otherwise damaged wires

Additional comments for consideration regarding the P2739 code

If the control solenoid is functioning as it’s supposed to and all the circuits meet the manufacturer’s specifications, take a look at the torque converter, high-pressure pump, or even the PCM.
