What does the P0753 code mean?
The P0753 code is a diagnostic trouble code related to the shift solenoid A electrical circuit. This code is triggered when the transmission control module (TCM) detects an abnormal voltage or resistance level in shift solenoid A’s electrical circuit.
The shift solenoid is responsible for controlling the hydraulic pressure in the transmission, which in turn controls the shifting of gears. When the TCM detects a problem with the shift solenoid, it illuminates the check engine light and stores the P0753 code.
If the solenoid goes through a short circuit or another type of issue, it may affect the performance of the TCM and make your car less safe to drive due to bad gear shift timing and it can even affect the fuel efficiency of your car.
What causes the P0753 code?
So by now, you can already tell that the code has something to do with the shift solenoid’s operation, but you won’t be able to fix it unless you can figure out the underlying issue. To cut your worries short, we’ve created a list of the most expected (and a few unexpected) reasons behind the code P0753 activation:
Faulty shift solenoid
A faulty shift solenoid is the most common cause of the P0753 code. This issue can arise due to wear and tear, corrosion, or damage to the solenoid’s wiring or connector. Symptoms of a faulty shift solenoid include harsh shifting, delayed shifting, and transmission slipping.
Low transmission fluid
Low transmission fluid can also cause the P0753 code to appear. Insufficient fluid levels can cause the transmission to overheat, which can damage the shift solenoid. Additionally, low fluid levels can cause erratic shifting and slipping.
Transmission control module (TCM) malfunction
A malfunctioning TCM can also trigger the P0753 code. This issue can arise due to a software malfunction, wiring issues, or a faulty TCM. Symptoms of a malfunctioning TCM include hard shifting, delayed shifting, and transmission slipping.
Which car models does the P0753 code affect the most?
We gave it our best to search through NHTSA’s complaints and testimonies of drivers that experienced the most problems with the code P0753 based on a specific vehicle model. What we were left with is a list of a few cars that proved to be less reliable in that sense, so they frequently experienced the code P0753:
- Nissan Altima: In the case of the Nissan Altima, the issue is related to a faulty transmission control module (TCM) that can cause solenoid failures and result in P0753 codes. Nissan has acknowledged this issue and issued recalls for affected vehicles.
- Ford Mustang: For the Ford Mustang, the issue is related to a design flaw in the transmission control module that can cause it to overheat. This, in turn, can lead to solenoid failure and P0753 codes. Ford has also issued recalls for affected vehicles.
How to diagnose the P0753 code
Diagnosing the P0753 code requires specialized diagnostic tools and equipment. Here are the steps to diagnose the code:
Scan the vehicle’s computer
The first step in diagnosing the P0753 code is to scan the vehicle’s computer using an OBD-II scanner. This scanner will retrieve the code and provide additional information about the issue.
Check the transmission fluid level
After scanning the vehicle’s computer, check the transmission fluid level. If the fluid level is low, add fluid to the appropriate level and check for any leaks.
Inspect the shift solenoid
If the fluid level is not the issue, inspect the shift solenoid for damage, corrosion, or wear. Check the wiring and connector for any damage or loose connections.
Check the TCM
If the shift solenoid is functioning correctly, check the TCM for any software malfunctions or wiring issues. Perhaps there’s another malfunction with TCM-related components in this case, so having an experienced mechanic take a look into it can save you trouble.
How to fix the P0753 code
Fixing the P0753 code will depend on the underlying cause. Here are some potential fixes for each cause that we’ve mentioned so far:
Faulty shift solenoid
If the issue is a faulty shift solenoid, the solenoid may need to be replaced. The cost of this repair can range from $150 to $400. Once the solenoid is replaced, it should lead to the proper information flow to the TCM and that should fix the issue.
Low transmission fluid
If the issue is low transmission fluid, you can add fluid to the appropriate level and check for any leaks. You may not realize it, but the loss of transmission fluid is one of the most common culprits behind all sorts of transmission-related problems, and the same goes for issues with the code P0753.
At least this one is an easy fix since you can top up the fluid level yourself, or have a mechanic look for leak spots if there’s a leak somewhere in the system.
Transmission control module (TCM) malfunction
If the issue is a malfunctioning TCM, the TCM may need to be replaced. The cost of this repair can range from $400 to $800. This is one of the worst-case scenarios so you should make sure that a faulty module is the reason behind the code before attempting to replace it with a new one.
How to prevent the P0753 code
Routine maintenance is the key to preventing the P0753 code from appearing. Here are some preventative measures:
- Regularly check the transmission fluid level and add fluid as needed.
- Change the transmission fluid and filter at manufacturer-recommended intervals.
- Avoid aggressive driving, which can cause the transmission to overheat.
- Seek professional help immediately if any issues arise to prevent further damage.
In conclusion, the P0753 code is a significant issue that can cause serious problems if left unaddressed. As long as you make sure to keep up with these maintenance tasks, you should be carefree when it comes to dealing with any sort of transmission system damage.
Our take
As it turns out, the code P0753 is one of the most common TCM-related error codes you can diagnose in your car, and many drivers aren’t aware of its cause. So, before you get the idea of doing a costly TCM replacement, consider the steps listed in this guide to diagnose and fix the issue.
Sometimes it can simply be something plain and simple like the solenoid replacement, which can at least be much more convenient for your wallet.
How serious is the P0753 code?
The seriousness of the P0753 code depends on the specific symptoms that are present in the vehicle. If the vehicle is still shifting properly and no other transmission problems are present, then the issue may be minor. However, if the vehicle is experiencing harsh shifting, slipping, or other issues, then the problem could be more serious and potentially lead to further damage if not addressed.
Can I continue to drive my vehicle with a P0753 code?
If your vehicle is experiencing no noticeable symptoms and is shifting properly, then it may be safe to continue driving. However, if you are experiencing harsh shifting, slipping, or other issues with your transmission, then it’s best to have your vehicle inspected by a professional as soon as possible.
How can I fix the P0753 code?
The specific solution to a P0753 code will depend on its underlying cause. In some cases, it may simply involve replacing a faulty solenoid or repairing wiring issues. In other cases, it may require more extensive repairs to the transmission or TCM. It’s best to have your vehicle inspected by a professional to determine the exact cause of the code and the appropriate solution.
