The P0755 code indicates an issue with your transmission shift solenoid. This will apply to whichever shift solenoid that your make and model has indicated is the “B” solenoid; different vehicles may consider the “B” solenoid to be in different places. The problem that the P0755 code indicates is that the gear ratio used in the gear shift is different from the expected gear ratio, depending on the calculations the engine is using. Some vehicles may require more than one inaccurate transmission before setting this code.
More About the P0755 Code
Shift solenoids are part of an automatic transmission. Automatic transmissions use these solenoids to open and close valves, allowing transmission fluid to run through the vehicle in the correct manner for all your shifting needs. If your shift solenoid is malfunctioning, then it may not be able to shift gears appropriately, which can even make your vehicle completely undrivable. Most vehicles with automatic transmissions have at least three shift solenoids, although many modern vehicles have more than three.

What Are the Symptoms of a P0755 Code?
There are a number of symptoms you might experience with the P0755 code. These include anything from just the check engine light turning on to more serious issues like your vehicle getting “stuck” in a specific gear or being unable to move while in gear. You can also experience a variety of other transmission-related issues, such as delayed, harsh, and erratic shifts, as well as the transmission overheating.
What Are Some Causes of a P0755 Code?
There are a number of causes that might contribute to a P0755 code. This may include issues with your transmission fluid, such as a low fluid level or dirty transmission fluid. It can also be due to problems with your wiring or connectors in any part of this system. Finally, it may be due to issues with a faulty transmission pump, solenoid, or valve body, all of which can lead to these issues.
How Serious Is the P0755 Code?
The P0755 code tends to be a problem that will increase over time. Although it might not seem especially severe right now, it’s very likely that you will see worsening issues over time, causing you to eventually need more significant fixes for the issue. The best thing to do is to assume that your P0755 code will be very serious, which will help you fix the problem early on.
Can I Still Drive with a P0755 Code?
While your vehicle may technically drive with the P0755 code active, it’s not a good idea. Oftentimes, the issue can cause serious problems within your gears, including issues with the vehicle getting “stuck” in gear or being unable to move when in a specific gear, which is very dangerous if you’re on the road. Additionally, decreased fuel economy means that your vehicle may actually be more expensive to run than it is to get the problem fixed.
How Easy Is It to Diagnose a P0755 Code?
The diagnosis process of the P0755 code can be difficult simply because there are so many possible causes. You need to check the transmission fluid, wiring and connectors, solenoid, transmission pump, valve body, internal pressure, and even the powertrain control module (PCM) and related areas. The more of these components you know how to check, the easier the diagnosis process will be, but many DIYers don’t know how to check these components, which can lead to general problems.
How Difficult Is It to Inspect a P0755 Code?
The inspection process, as with the diagnosis process, can be very difficult for the P0755 code. Many people don’t know how to inspect the transmission from home, and issues with the inspection can even lead to further problems that you might not be aware of. For most people, it’s best to give this problem over to an expert, who will be able to help you fix the problem without accidentally making it worse.
Need Additional Help with Your P0755 Code?
The P0755 code can be very difficult to fix on your own, and it’s generally better to hand this problem over to an expert rather than fixing it yourself, especially if you’re not well-versed in your specific make and model. A professional will be able to fix the problem much more effectively on average, making it a great solution for people who might not be comfortable dealing with this problem.
Start your process by finding a repair shop in your area using the KBB service center locator. This is a helpful way to find a very local service center, which can be necessary if you’re experiencing such severe issues that you’re concerned about driving your vehicle very far.
Additionally, it’s common for serious problems like this one to come with other OBD codes. Check out the OBD-II database to learn more about these codes and determine how to fix them.
