<<See All OBD Codes

Finding an issue with your car can be stressful, and an OBD code may leave you confused. Well, we have the answers for you, so read on and don’t worry. The P2737 code is defined as a Pressure Control Solenoid "F" Control Range/Performance. This code is set when the Transmission Control Module (TCM) of your vehicle notices that the Pressure Control Solenoid isn’t working as needed.

Your vehicles TCM helps it to transmission into different gears so that you can have a smooth ride in your vehicle. The TCM employs the Pressure Control Solenoid to be able to control the hydraulic pressure within the transmission. This is needed so that the various clutch packs can be applied which then enable the various gear ratios to be applied so that the vehicle can efficiently propel on road. The PC solenoid is basically an electronic pressure regulator, and controls the transmission line pressure as per the current flow through its coil windings. When the current flow increases, the magnetic field produced moves the solenoids plunger further away from the exhaust port, which ultimately decreases the output fluid pressure. This then results in a decrease in line pressure, the line pressure solenoid valve is responsible for regulating oil pump discharge pressure. This is done to suit the drivers need and respond to the signals from the TCM. Any issues noticed result in the P2737.

What causes this problem with the Pressure Control Solenoid "F" Control Circuit Range/Performance?

• Defects of the Pressure Control Solenoid
• Dirty or contaminated transmission fluid
• Transmission filter is dirty or clogged
• Defect in the Transmission Pump
• Defects present in the Transmission Valve Body
• Restrictions in the hydraulic passages
• Corrosion or damages of the connectors
• Faults in the wiring, possible damages also present
• Malfunction of the PCM

1. Electronic Pressure Regulator - Works by employing a push valve and a vent valve to be able to maintain the desired outlet pressure. A faulty regulator can cause the P2737 code to set. Fix it via repairs or replacement. You can search for the one for your vehicle using the easy and simple searching options on PartsAvatar.
2. Transmission Control Module - Is the module that helps change the gears so that the vehicle can function on road. A TCM fault can very much cause error code P2737 to set. In order to fix this issue you will have to either repair or replace the TCM. Find the perfect fitment TCM for your vehicle today on PartsAvatar. Order online from the comfort of your home and have it reach your doorstep in just days!
3. Oil Pump - Helps in circulating the engine oil under pressure to the rotating bearings, the sliding pistons and the camshaft of the engine. This process helps lubricate the bearings and thereby allows use of higher-capacity fluid bearings and also assists in cooling the engine. A faulty pump can be the reason why you have the P2737 code set. Fix this problem via repairs and see if the code persists, if it does; then you will have to opt for replacement. You can choose from a wide range of brands and prices to get the one suiting your budget and quality. PartsAvatar ships to the remotest corners of Canada, so don’t worry about cross border shipping charges or any delays.
4. Pressure Control Solenoid Valve - Is responsible for controlling the fluid pressure to the internal friction plate clutches or drum bands of your vehicle. A bad or failing transmission pressure control solenoid can cause multiple issues like slipping, which causes the transmission to heat up. You will also note the P2737 code to set due to a faulty PC solenoid valve. Try to fix the problem by repairs or replacement as needed.
5. Transmission Pump - Is the pump that helps in circulating the fluid. A faulty pump can harm the whole TCM. Try to fix the problem via repairs or replace it.
6. Powertrain Control Module- Is the processing unit of your vehicle which manages all the other modules so that your car functions smoothly. A faulty PCM can result in random codes to be set, so try to fix it first. If that doesn’t help you will have to replace it. Replacing the PCM requires reprogramming. Ensure you take help from a professional diagnostician for this. Find what you’re looking for on PartsAvatar and avail free shipping on orders over CAD $99.
7. Transmission Valve Body- A crucial part of the TCM, the Transmission valve body works in a network system. It directs pressurized transmission fluid to a network of valves which put together correct clutch packs for smooth gear functioning. You will have to resolve the issue with the transmission valve body to get rid of the P2737 code. You can find one on PartsAvatar, order online and track your shipment till it reaches your doorstep.

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P2737 code by mentioning some major symptoms below:

Common Symptoms

• Increase in the consumption of fuel as compared to before
• The Check Engine Light gets activated
• You may find the Transmission overheating
• A slip of Transmission when shifting becomes common
• It is hard to shift transmission
• Misfire-like symptoms are present
• PCM puts the transmission into limp mode

It is very important to fix the fault code P2737. So here are some ways with which you can correct this issue:

• Change the fluid and filter
• Replace faulty Pressure Control Solenoid or repair it if possible
• The faulty transmission pump will need to be repaired or replaced
• The Transmission valve body needs repairs or replacement
• Flush the transmission to clean passages
• Clean the corrosion from connectors and check wiring and circuitry for damages
• PCM needs Flashing or replacing

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

Here are some steps which you should follow in order to diagnose this P2737 fault code:

The first step is to research the Technical Service Bulletins (TSB’s). For this you will have to match your vehicle’s year of manufacture, model and transmission. The reason why the TSB should be referred is mainly to save you time, and effort. It serves as a great tool during diagnosis.

Second step -Fluid check: Measure the level of fluid and also observe the condition of the fluid for any dirt or contamination. Don’t be hasty in changing the fluid, check the vehicle records to see when the fluid and filter change was done last. Depending on what you have found, you can proceed to changing the fluid or simply skip this step if the fluid level and purity is good.

Third step -Wiring inspection: Moving on to the wiring, perform a detailed visual examination and see if there are any damages present. Continue inspection of the connectors and see if the pins are corroded, bent or damaged. Check the wires and connectors going to the transmission pressure solenoids, transmission pump as well as the PCM. Depending on the type of vehicle the transmission pump may be driven electrically or mechanically. Fix all the issues you have found by conducting repairs or replacements as required.

Fourth Step -Continuity Check: These will be done to figure out the problem if it wasn’t with the fuel, filter or electrical components. Continuity check is an advanced step, and hence will need certain tools like a digital multimeter and the specific technical references for the vehicle. Get hold of them and also all the troubleshooting information for your particular vehicle from the TSBS.

Fifth Step- Voltage Check: To confirm the voltage and fluid pressure requirements you will need to refer the TSBs. In terms of continuity checks, they will usually be 0 ohms of resistance, but for safety refer your vehicles information source. When performing the continuity checks you have to ensure that power is removed from the circuit. This is important to avoid shorting the circuit and causing more damage to the vehicle. If you find that there is no continuity or resistance then that’s an indication that there is faulty wiring present which may be open or shorted and needs to be repaired/replaced.

Common Mistakes When Diagnosing the P2737 Code

• An issue of engine misfire present
• Problem present with the Transmission pump
• An Internal transmission issues
• A driveline issue present
