How do you fix the code P0750?
Encountering the P0750 error code can be frustrating, especially if you're unsure what it means or how to address it. This code indicates a problem with the Shift Solenoid "A" in your vehicle's transmission system. At Kevin's Autos, we’ve seen this issue many times and are here to guide you through the steps to diagnose and fix it effectively.
What Does the P0750 Code Mean?
The P0750 code is a generic OBD-II trouble code that signifies a malfunction in the Shift Solenoid "A" circuit. Shift solenoids are critical components in an automatic transmission, as they control the flow of transmission fluid to engage the appropriate gears. When this solenoid fails or its circuit is disrupted, your vehicle may experience shifting problems or even fail to shift altogether.
Symptoms of the P0750 Code
If your vehicle has triggered the P0750 code, you may notice the following symptoms:
- Check Engine Light is illuminated.
- Difficulty shifting gears or failure to shift.
- Transmission stuck in one gear (often limp mode).
- Decreased fuel efficiency.
- Unusual noises coming from the transmission.
Common Causes of the P0750 Code
Several factors can lead to the P0750 code being triggered. These include:
- Faulty Shift Solenoid "A".
- Wiring issues, such as damaged or corroded wires in the solenoid circuit.
- Low or dirty transmission fluid.
- Faulty transmission control module (TCM).
- Mechanical issues within the transmission.
Steps to Diagnose and Fix the P0750 Code
Follow these steps to diagnose and resolve the P0750 code:
- Step 1: Check the Transmission Fluid
Start by inspecting the transmission fluid. Low or dirty fluid can cause solenoid malfunctions. If the fluid is low, top it off with the manufacturer-recommended type. If it’s dirty, perform a transmission fluid flush.
- Step 2: Inspect the Wiring and Connectors
Examine the wiring and connectors leading to the Shift Solenoid "A". Look for signs of damage, corrosion, or loose connections. Repair or replace any damaged components.
- Step 3: Test the Shift Solenoid
Using a multimeter, test the resistance of the Shift Solenoid "A". Compare the readings to the manufacturer’s specifications. If the solenoid is out of spec, it may need to be replaced.
- Step 4: Scan and Test the TCM
Use an advanced diagnostic scanner to check for additional codes or issues with the Transmission Control Module. If the TCM is faulty, it may require reprogramming or replacement.
- Step 5: Consult a Professional
If the issue persists after performing the above steps, it’s time to consult a professional mechanic. At Kevin’s Autos, we have the tools and expertise to diagnose and repair complex transmission issues.
Preventing Future P0750 Errors
To avoid encountering the P0750 code in the future, follow these maintenance tips:
- Regularly check and change your transmission fluid as per the manufacturer’s recommendations.
- Inspect wiring and connectors during routine maintenance to catch potential issues early.
- Address transmission issues promptly to prevent further damage.
Conclusion
Fixing the P0750 code requires a systematic approach to identify and resolve the underlying issue. While some steps can be performed at home, others may require professional assistance.

Frequently Asked Questions
What causes shift solenoid code?
It's common for there to be issues with the transmission fluid, whether you don't have enough fluid or the fluid is dirty. You might also see damaged connectors or wiring. The solenoid, transmission pump, or valve body can also be damaged or have another issue.
How much does it cost to fix a shifting solenoid?
In general, a single faulty transmission solenoid replacement costs approximately $250. Replacing the entire solenoid pack can cost around $400. As you can see, replacements are often costly, so you want to make sure that you do not replace a functional shift solenoid.
Can I still drive my truck with a bad shift solenoid?
However, it isn't recommended. Driving with a bad transmission solenoid can damage your transmission even more, leading to costly repairs. It's best to take your ride to an auto repair shop once you notice any of the symptoms of a bad transmission solenoid.
How do you fix a shift solenoid A that is stuck on?
How To Correct P0752 Shift Solenoid A Stuck On
- Check out the transmission filter carefully; Replace it if it is clogged or broken.
- Replace the faulty Shift solenoid.
- Check out the level of transmission fluid and top up if required.
- Change the transmission fluid if you discover if dirty or contaminated.
How to reset transmission solenoid?
- Step 1: Turn off the vehicle's air conditioner and set the car into Park (P) position to prevent it from freewheeling.
- Step 2: Wait around 20 seconds before turning the ignition off.
- Step 3: Wait at least 10 seconds, then start the engine and let it idle for a couple of seconds.
Can I drive with a bad transmission shift solenoid?
You can still drive your vehicle even if it has a malfunctioning transmission solenoid. However, it isn't recommended. Driving with a bad transmission solenoid can damage your transmission even more, leading to costly repairs.
How much does it cost to replace a transmission shift solenoid?
In general, a single faulty transmission solenoid replacement costs approximately $250. Replacing the entire solenoid pack can cost around $400. As you can see, replacements are often costly, so you want to make sure that you do not replace a functional shift solenoid.
How do you replace a transmission shift solenoid?
Replacing a transmission shift solenoid or a shift solenoid pack involves dropping the transmission oil pan in order to access the valve body, (where the solenoids/solenoid pack is mounted), locating and replacing the faulty solenoid and then replacing the oil pan using a new pan gasket before refilling the ...
How do you know what shift solenoid is bad?
A 'bad' solenoid will prevent the car from shifting up from a lower gear to a higher one. You will hear it when you drive as the RPM will keep climbing and you won't be able to accelerate anymore. You are stuck in 1st or 2ndmaybe 3rd if you have a transmission with a lot of gears.
Will disconnecting battery reset transmission?
Disconnecting the battery cable for a short period will not fully reset your ECU because residual power remains in the circuits. If you want to perform a full reset, wait at least 15 minutes before reconnecting the battery to ensure all residual power has been drained.
