You might’ve encountered a P0750 code on your scan tool before and wondered what it meant. P0750 is a diagnostic trouble code (DTC) that indicates an issue or multiple issues with your vehicle. Read on to find out more about this DTC and how to deal with it.
Diagnostic trouble code P0750 code stands for “Shift Solenoid ‘A’.” This is a generic transmission code that applies to select vehicles with OBD-II. You might encounter this code in certain vehicles manufactured after 1996, which include vehicles from Chrysler, Ford, Dodge, Hyundai, Toyota, and many more.
If your vehicle’s powertrain control module (PCM) detects a malfunction within the shift solenoid “A” circuit, it can register a P0750 code. The shift solenoid “A” circuit is one of the solenoids in your vehicle’s automatic transmission. The exact location of the shift solenoid “A” circuit can vary depending on your vehicle’s make, model, and transmission configuration.
Shift solenoids are components in your vehicle’s automatic transmission that regulate the amount of fluid between hydraulic circuits and change the transmission gear at the right time. A P0750 code can indicate a general malfunction within the “A” circuit, so you might have to check all the parts that are associated with it.
The code appears in a 2007 Dodge Ram 1500 SLT 5.7L because of the following conditions:
Note: The definition of code P0750 might be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.
A P0750 code can be caused by a number of factors. Here are some of the most common causes of P0750 code.
Some codes associated with the shift solenoid “A” circuit include P0751, P0752, P0753 and P0754. Multiple DTCs can be stored in your vehicle’s PCM at once. However, if your PCM only has a P0750 stored, you can expect one or more of the following symptoms to manifest.
When diagnosing a P0750 code, it’s important to consider your vehicle’s make, model, and transmission configuration. Your vehicle’s manufacturer might have a different diagnostic and repair procedure from the one shown in the following video.
Now that you’ve narrowed down the problem with your vehicle, it’s time to start troubleshooting. Here are some ways you can fix a P0750 code:
First, you’ll have to test your shift solenoid to make sure it’s actually the issue. This is where things can get a little complicated. Some manufacturers recommend testing your solenoid with the engine running, while others ask that you switch to a specific gear first.
Check with your owner’s manual first so that you can safely test your shift solenoid according to its instructions.
In some cases, you can solve a P0750 code with a simple transmission fluid change or refill. First, you’ll have to perform a thorough visual inspection of your transmission fluid: is it still clean, or has it turned dirty over time from debris and other contaminants? Is there enough fluid in the system, or is your transmission running dangerously low?
Both of these issues can seriously damage your transmission, so you’ll want to act fast to get rid of whatever’s causing your vehicle to throw a P0750 code. However, keep in mind that these are only common repairs that might not work for every vehicle. What solves a P0750 on a Ford might not work on a P0750 on a Dodge. If you aren’t sure what to do, it might be best to call your local mechanic for help.
