The P0750 code indicates that the shift solenoid, which is one of the devices that controls the flow of transmission fluid within the unit, has malfunctioned in some way. This diagnostic code indicates a problem with shift solenoid A, which is the solenoid responsible for switching your car between first and second gear, which means that if you don’t handle the problem, the car will at some point become unable to shift out of first gear.
More About the P0750 Code
Solenoids work with the powertrain control module (PCM) to switch gears in an engine. In an automatic transmission, this process needs to happen with no input from the driver, and the intention of the solenoid is to make sure the engine is functioning at optimum power for whatever speed you’re at. This specific code indicates that the powertrain control module (PCM) isn’t seeing the expected RPM change when it would expect the car to switch into second gear.

What Are the Symptoms of a P0750 Code?
This code can be very heavily impactful not only on your driving but also the health of the car. That’s why the check engine light will come on with this code. Additionally, you should expect that, at the very least, you’ll start noticing issues with switching from first gear to second gear; in some instances, your car may be unable to switch from first gear to second gear at all, leading to a top speed of around 35 miles per hour and sending the car into limp mode.
What Are Some Causes of a P0750 Code?
Issues with transmission fluid are some of the most common causes of this problem, whether it’s a low transmission fluid level or dirty transmission fluid. There may also be problems with the wiring and connections, as well as potential problems with the A solenoid, the transmission pump, or the valve body; in some very rare instances, it may be a problem with failure of the PCM.
How Serious Is the P0750 Code?
This code can be incredibly serious, as any codes with the transmission often are. Not only can this code eventually harm your ability to drive if it isn’t already, but refusing to handle the code will inevitably result in damage to your transmission, by far one of the most important parts of your vehicle and one of the more expensive parts to fix.
Can I Still Drive with a P0750 Code?
Experts do not recommend driving if your engine is throwing a P0750 code. Not only can this code sometimes mean that your car is unable to go above around 35 miles per hour, but the more you drive on it, the higher likelihood you have of seriously damaging your transmission. Instead, it’s important that you take your vehicle to a local repair shop safely, whether you’re able to drive it there or you need to call a tow truck.
How Easy Is It to Diagnose a P0750 Code?
If the problem with this code is not that you need to refill or replace the transmission fluid, then it can be very difficult to diagnose a P0750 code. There are many different elements within the engine that can be causing it, and you need to know how to understand all of these causes and check for each one of them. Instead of trying to fix the problem on your own, take your vehicle to an expert and let them check.
How Difficult Is It to Inspect a P0750 Code?
The inspection process for a P0750 code is also frequently very difficult. You need to be able to check wiring and connectors for signs of damage and corrosion, which may be more difficult than you might think; additionally, if your wiring isn’t the problem, the process of inspection requires you to test the solenoids and other components, which are in-depth processes that many DIYers have a difficult time handling. Unless you’re an advanced car repair DIYer, leave this problem to the experts.
Need Additional Help with Your P0750 Code?
If your vehicle is throwing the P0750 code, then you might be able to replace or refill the transmission fluid and fix the problem. However, if the problem doesn’t go away just with a careful transmission fluid fix, it’s likely that you’re dealing with a more difficult issue that might need an expert’s careful handling. That’s where a local repair shop can come into play.
With Kelley, you can easily find a repair shop in your area that’s able to help you with the problem you’re experiencing, no matter what it might be. This includes if your engine is throwing other codes outside of this one.
