The P07A5 code definition is “Transmission Friction Element B Stuck On.” This usually means that your vehicle’s powertrain control module (PCM), engine control module (ECM), or transmission control module (TCM) has identified an issue with a friction element within your transmission being turned on. There are many friction elements within transmissions, so you’ll need to check your vehicle’s service manual to learn what friction element “B” is in your transmission. This generic powertrain diagnostic trouble code applies to a variety of OBD-II vehicles. It can sometimes even apply to a manual transmission engine type as well as an automatic transmission type.
More About the P07A5 Code
Your transmission needs to utilize a variety of friction elements to maintain the highest level of function. In this case, a “friction element” refers to a clutch pack, which allows for a small amount of slippage when changing gears or engaging the drive in an automatic transmission. Oftentimes, this code has to do with your automatic transmission not releasing the appropriate clutch pack referenced by the code stored. If your vehicle tries to shift when the clutch hasn’t released properly, it can cause a significant amount of harm to your transmission overall. However, this code is also quite vague; while the clutch is a common problem for DTC P07A5, it’s definitely not the only one. You’ll absolutely need to check other error codes and more vehicle information sources to determine what this code refers to in your vehicle.

What Are the Symptoms of a P07A5 Code?
The top symptom to look for in the P07A5 code is the check engine light turning on. However, outside of this, the symptoms that you’ll see may have to do with issues surrounding smooth transmission shifting. This may include erratic driving conditions, including abnormal shift patterns and abnormal power output, as well as a worn friction element over time, which could come with its own array of symptoms. This error code can definitely cause some pretty serious symptoms, but the exact symptoms you experience will likely shift depending on the core problem.
What Are Some Causes of a P07A5 Code?
There are many possible causes related to the P07A5 code; however, this code is extremely vague, so you’ll need to look into the code for your vehicle before determining what code P07A5 refers to. Here are some causes that might have an impact on a vehicle developing this code.
- Unsymmetrical circumstances (uneven tire sizes, incorrect tire pressures)
- Low or dirty automatic transmission fluid
- Water damage
- Issues with electrical connection, such as connector pins
- Not maintaining proper maintenance schedules
- Damage to module internally
- Steering gear internal failure
- Contaminated gear
Most cases of this code will include supporting codes. Checking these supporting codes is critical to determining the underlying problem.
How Serious Is the P07A5 Code?
Most experts will suggest that you consider this code as being fairly serious. It’s true that in some cases, the code is due to a fairly small or easy-to-fix problem—for example, if the issue is just an imbalanced vehicle due to tire air pressure, a few basic steps will easily fix the problem. However, if the problem is water damage or electrical connection concerns, it will only proceed to get worse over time unless you fix it. When it comes to transmission codes, it’s always best to get help from an expert to avoid a complete failure.
Can I Still Drive with a P07A5 Code?
In many cases, you may indeed still be able to drive with the P07A5 code active, especially if the core problem isn’t very significant. However, you shouldn’t continue to drive when this code is active. Avoiding what may be a simple service to fix the problem could result in consistent wear on the friction elements, eventually requiring you to replace entire components within the engine. The worst-case scenario is that you might actually have to replace the entirety of the transmission. Avoid this by talking to an expert at an auto repair shop.
How Easy Is It to Diagnose a P07A5 Code?
Diagnosis for the P07A5 code is often fairly difficult. As you’ve already seen, determining the exact repair steps is impossible just by looking at this code. You need to look into the problem behind this code, which isn’t as easy, especially given the many possibilities. If you’re not an expert, finding the core problem behind these codes can be quite daunting. Avoid trying to diagnose this problem yourself—talk to an expert for a more thorough look at the issue.
How Difficult Is It to Inspect a P07A5 Code?
To inspect code P07A5, you’ll need to look at the transmission, which is one of the most central and difficult-to-handle parts of your entire vehicle. Even for a fairly experienced DIYer, this is a daunting task. It’s made even more stressful by the fact that you’ll need to consider elements such as service bulletins and potential recalls. Avoid stressing out over these problems by talking to a professional technician instead of trying to handle them on your own.
Need Additional Help with Your P07A5 Code?
There are many good reasons to try to get additional help with your P07A5 code. The good news is that with so many options available, it’s easy to find an expert who can really help.
To start, you can find an auto repair shop in your area. Finding a local auto repair shop will allow you to get a fix without having to drive especially out of your way to do it.
You can also check out the OBD-II database at KBB.com. Using your scan tool to find other error codes within your vehicle is an important part of diagnosing the problem, but you can also do it at home to understand the general extent of the problem and figure out what you might see when you get to the shop.
