Why Does My Ford Fusion Say 'Shift System Fault'?

When a "Shift System Fault" message and check engine light illuminate, such powertrain control module (PCM) has identified a transmission system fault.

When this light illuminates, a defect code is recorded in the PCM's memory. This code indicates why the light is illuminated and what may be required to resolve the issue.

P0756 and P0766 were reported by your Ford vehicle. Shift solenoids "C" and "D" transmission performance codes. This implies that when such solenoids are employed, the PCM does not see the shifts as they should.

This might be an issue with a low fluid level, a solenoid, a valve body, or an internal transmission.

There are currently no technical service advisories available for this issue. However, there is a recall. Recall that 20B34 relates to a probable failure of the transmission cooler.

Ford will replace your transmission cooler free of charge. If this cooler fails and the transmission fluid is low, this might be the source of your difficulties.

If indeed, the cooler has not failed, you must get your transmission evaluated to determine the source of the problem.

Your Ford vehicle employs an electronic shifter to interact between the shifter and the transmission computer. This warning appears when the shifter component itself is malfunctioning.

Perhaps an internal electrical malfunction or a problem with the wiring to the shifter.

You'd need a scan tool to see if the shifter is communicating correctly; if it isn't, you can presume that perhaps the shifter assembly has managed to fail or that there is a wiring problem at the shifter assembly.

More About A Shift System Fault

The shift system fault indicates that perhaps a problem has been found chiefly with shifter electronics or even one of the transmission electronics. Unfortunately, this problem can be caused by a variety of electronics.

The problem codes must be read/checked using an entirely suitable scan tool or computer hooked directly to your vehicle's data port.

This must be a gadget capable of reading your model's systems. Following this, at least one error code should be set in any vehicle's computers.

The code is then diagnosed, leading to the problem's root cause. Once the root cause is identified, you may correct the defect. You must do this to assist in pinpointing the problem, and it should be the initial step.

Testing will need to be done from there to assist in identifying the defect and repairing it effectively. We assume this problem involves one of the shifter circuits that you must change.

Why Shifting Problems Occur

Several more factors might create problems while shifting gears. If the catalytic converter or exhaust is blocked, the engine may feel back pressure, making it difficult for the gearbox to shift gears.

Causing it to trigger the shift system to pop up a warning. Shifting issues might also be based on:

  • Interlock switch failure error means that the device necessitates using the brake pedal to change from park to drive or reverse. If shifting from the park is difficult, this might cause a malfunctioning interlock.
  • Shift Cables and Linkages can get rusted or covered with heavy grease. Other factors, such as moisture, oil, and even dirt, can affect your shift cables and linkages, which results in difficulty in shifting. This mostly happens when you haven't warmed up the engine and heat box enough. The gunk softens after you have warmed up your engine enough.
  • Low transmission fluid may also be the reason for your car's sluggishness and difficulty in shifting gears. Transmission fluid is the transmission's main go-to fluid for keeping the parts cool and lubricated. Moderate transmission fluid flushing is critical to keep a long-lasting life for your transmission.
  • The internal computer in your car may be causing the error or malfunctioning. The internal computer in a vehicle communicates with all the transmissions, including shifting between park to drive or park to reverse and even when natural shifting occurs while driving.

Why Your Car Has A Check Engine Light

Checking the engine light is the most apparent sign of anything wrong with your car, gearbox, or otherwise. The engine light can signal a variety of problems beneath the hood.

When the transmission triggers the light, it typically means that sensors within the car have detected vibration or other subtle abnormalities that the driver may overlook.

The engine light may illuminate if the transmission is overheated, the transmission fluid is low, or the sensors are defective, among other things.

Consultation with a skilled specialist is the best approach to discovering why and what needs to be remedied.

A technician can diagnose to learn when your transmission is to blame or whether a minor repair is required.
