P0782 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P0782 can be described as 2-3 Shift Malfunction. If the PCM would identify some fault in the 2-3 shift malfunction, then the powertrain control module would trigger up the P0782 error code.

Don’t worry if P0782 error code is triggering again and again. We offer wide range of auto parts at affordable prices to our dear customers. It would mean that an issue in the automatic transmission shifting has been detected. The trouble is generally caused due to mechanical failure or the electronic malfunction. You must keep this in mind that this fault code is exclusive to vehicles with automatic transmission.

What causes this problem with the 2-3 Shift Malfunction?

• Issue of electrical short to power
• There can be an electrical short to ground
• 2-3 shift solenoid might be defective
• The power or ground circuit wiring might be opened or disconnected
• TCM or PCM might have failure internally

1. Automatic Transmission Fluid - Do you remember when was the last time you got your car Automatic Transmission Fluid checked up? A dirty Automatic Transmission Fluid can cause a lot of issues like displaying P0782 code.
2. Powertrain Control Module - Poor Powertrain Control Module can cause a lot of difficulties, so why not get it replaced at time?
3. Speed Sensor - Are there some faults in your Speed Sensor? Don’t waste time and get them replaced or else P0782 code can turn up.
4. Body Control Module Component - OBD Code P0782 can appear because of faulty Body Control Module Component.
5. Automatic Transmission Sensor - Everything is fine with Body Control Module Component and still P0782 code triggering? Then you must get your Automatic Transmission Sensor checked.

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P0782 code by mentioning some major symptoms below:

Common Symptoms

• Transmission slipping
• Transmission extravagant heating
• Visibility of the check engine light
• There can be a failure to shift into or out of gear
• Transmission might get stuck in “limp-home” mode
• Grinding shifting
• The fuel efficiency might start dropping

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P0782:

• The leakage in the transmission should be repaired
• Repair or replace the quirky transmission
• The malfunctioning circuits, shift solenoid or shift solenoids packs should be repaired or replaced as per the need
• You must fix the defective hydraulic pump
• Make sure to mend the faulty torque converter
• It is essential to restore the flawed wiring, connectors, and components
• Carefully adjust the faults in the PCM or TCM

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of automatic transmission module, oil pressure sensor, vehicle speed sensor, wheel sensor, transmission sensor and many more. Now all your problems would vanish within no time.

If you are willing to successfully diagnose the errors that can cause a P0782 trouble code, a mechanic should have an advanced scanner, a manual pressure gauge, hydraulic pressure diagram, and a digital volt/ohmmeter. Now once all these tools have been gathered, the mechanic should diagnose the trouble code by completing the following steps:

• The transmission fluid by should be inspected and this can be done by removing the dipstick. If the fluid smells burnt or looks unusual, then you should remove the transmission pan and inspect it properly for debris. After the transmission is rebuilt, if needed, fill it with fluid enough to fix any leaks.
• After it has been repaired, then you should fill the transmission fluid to its normal level. In addition to the fluid, inspect all the wiring, connectors, and components for any damage. The stored codes and freeze-frame data should be downloaded using the advanced scanner, and then clear the P0782 trouble code.
• Start the vehicle and it should be allowed to reach a normal operating temperature before test driving it to see if the code returns. Now if the code still exists, inspect the pressure of the hydraulic pump using a manual pressure gauge. With the aid of a hydraulic pressure diagram, determine the operating pressure of the pump and compare it to the manufacturer's specifications.
• If the code returns upon clearing, then inspect the reference voltage and ground circuits to see if any are open using the digital volt/ohmmeter. Using a manual wiring diagram, the mechanic should test all of the related circuits and the solenoid if they think a shift solenoid is at fault. After solenoid replacement, clear the code and retest the system.
• After that the powertrain control module should be inspected if everything checks out and the code persists. Upon replacing the PCM, if needed, clear the code and retest the system again to see if the code returning back or not.

Common Mistakes When Diagnosing The P0782 Code

A lot of people make a big mistake of attempting to diagnose the shift solenoid circuit. Save yourself a big headache and make sure that you are addressing the correct auto part before beginning your diagnosis.
