Shift Solenoid ‘A’ Performance or Stuck On
If your dashboard is flashing the P0752 trouble code, you’re likely here seeking clarity and a solution.
This guide unpacks the meaning, symptoms, causes, and how you can fix this issue.
Having tackled the P0752 code in numerous vehicles, I know exactly how frustrating and disruptive it can be.
In this post, you’ll learn precisely how the P0752 code affects your transmission’s operation, key symptoms to watch for, and step-by-step repair instructions.
Time to roll up our sleeves and get into the details.
Key Takeaways
- Code Definition: P0752 indicates a performance issue or a stuck ‘on’ condition in shift solenoid ‘A’.
- Symptoms: These include delayed shifting, unexpected neutral shifts, reduced fuel efficiency, and the check engine light turning on.
- Common Causes: Causes range from faulty shift solenoids to low or contaminated transmission fluid and electrical issues.
- Diagnostic Steps: Begin with a diagnostic scan, check the transmission fluid, and inspect the shift solenoid and electrical connections.
- Repair Strategy: Clean or replace the transmission filter if needed, replace faulty solenoids, and ensure all electrical connections are secure.
- Post-Repair: Reset the Transmission Control Module and take a test drive to confirm the problem is resolved.

What Does P0752 Trouble Code Mean?
Ever been cruising down the road when your car decides to throw a tantrum, lighting up your dashboard like a Christmas tree? If one of those illuminated symbols comes with a P0752 trouble code, you’re looking at a specific issue with your automatic transmission.
Let’s dive in.
In plain English, the P0752 code signals a problem with the shift solenoid “A” circuit. This solenoid is a little electronic wizard that controls the flow of hydraulic fluid to engage the correct gear.
Think of it as the middleman between you pushing the gas pedal and your car smoothly shifting gears without you noticing.
When your car’s computer, the brain of the operation, spots an issue with how this solenoid is behaving, it flags the P0752 code.
This can mean the solenoid is stuck open, stuck closed, or even that the electrical path it needs to operate is on the fritz.
Here’s the kicker:
A faulty solenoid can lead to noticeable problems. Your car might not shift into gear correctly, you could experience a drop in fuel efficiency, or it might even go into limp mode, where it locks into a single gear to prevent further damage. It’s like your car is saying, “I’m not happy, and now you won’t be either.”
Understanding this code is the first step in getting your smooth ride back. Remember, ignoring it is like ignoring a toothache—it won’t get better on its own and will likely lead to more complex problems down the road.
So, if your dashboard is giving you a heads-up with the P0752 code, it’s time to check under the hood or let a pro take a peek.
P0752 Trouble Code Symptoms
When dealing with the P0752 trouble code, you might notice several distinct symptoms, including:
- Delayed shifts or failing to shift
- Unexpected shifting to neutral
- Lower fuel efficiency
- Transmission slipping
- Engine stalling when coming to a stop
- Check engine light is on
- Vehicle entering limp mode
P0752 Trouble Code Causes
The P0752 trouble code can be triggered by a variety of issues within your vehicle’s transmission system, such as:
- Faulty shift solenoid ‘A’
- Blocked fluid passages in the transmission
- Low transmission fluid level
- Dirty or contaminated transmission fluid
- Transmission fluid leaks
- Electrical issues in the shift solenoid circuit
- Malfunctioning transmission control module (TCM)
How To Fix A P0752 Trouble Code
Resolving a P0752 trouble code involves a systematic approach to both diagnose the underlying issue and carry out the necessary repairs. Here’s how you can tackle this problem:
1. Diagnostic Scan
Start by using an OBD-II scanner to confirm the presence of the P0752 trouble code and check for any other related codes. Codes in combination could indicate more complex issues.
2. Inspect Transmission Fluid
Check the level and condition of your transmission fluid. Low, dirty, or contaminated fluid can cause improper shifting. If the fluid is dirty or smells burnt, it should be replaced and the system flushed.
3. Examine Shift Solenoid and Wiring
Locate shift solenoid ‘A’. This is often accessible by removing the transmission pan. Inspect the solenoid and its wiring for any signs of damage or wear. Test the solenoid’s resistance with a multimeter to ensure it falls within the manufacturer’s specifications.
4. Check Fluid Passages
Ensure that the fluid passages in the transmission are not blocked. You might need to clean the transmission filter or replace it if it’s clogged.
5. Review Electrical Connections
Look for any loose or corroded electrical connections that might affect the solenoid’s operation. Clean and secure all connections.
6. Test or Replace the Shift Solenoid
If the solenoid is defective, it will need to be replaced. However, if tests show it’s functioning correctly, look at other potential electrical issues or the transmission control module itself.
7. Reset the Transmission Control Module
After repairs, reset the TCM to clear the fault code and relearn the transmission’s settings, which can be done with a professional scan tool.
8. Road Test
Finally, take your vehicle for a test drive to ensure that the issue has been resolved and that the transmission is shifting smoothly without any of the previous symptoms.
Addressing a P0752 trouble code may require some technical knowledge and comfort with vehicle maintenance. If you’re unsure, it’s advisable to seek help from a professional mechanic.
