<<See All OBD Codes

The trouble code P07A7 can be defined as Transmission Friction Element "C" Stuck On. Here we are referring to the automatic transmission. One thing which you must keep in mind that its symptoms as well as causes would surely vary as it depends upon a number of things. Just keep in mind that the initial thing which should be considered is the general health of the automatic transmission as well as automatic transmission fluid.

We learn more by looking for the answer to a question. That’s the reason why we are here to provide you the answers for all your questions. There are lot of friction elements required when a mechanical operation of an automatic transmission is being considered. The same friction materials like the clutch as used by the manual transmissions.

What causes this problem with the Transmission Friction Element "C" Stuck On?

• Tattered friction element
• ATF might be dirty
• There can be unbalanced rotational speed/circumference
• Flaws in the transmission control module
• Problems related to wiring
• ATF might be low
• Issue of unequal tire sizes
• Imperfect engine control module
• Module or harness might have water damage

1. Electronic Control Unit - The P07A7 code can also arise due to some issues in Electronic Control Unit. So, it is advised to replace them as soon as possible.
2. Body Control Module Component - Do you remember when was the last time you got your car Body Control Module Component checked up? A damaged Body Control Module Component can cause a lot of issues like displaying P07A7 code.
3. Automatic Transmission Filter - Automatic Transmission Filter is an important car part which should never be neglected. May be there is some fault in it due to which P07A7 code may start flashing.
4. Engine Control Module - Is your Engine Control Module damaged or broken? Don’t worry as we have solutions for all your problems.
5. Powertrain Control Module - Defective car Powertrain Control Module can be a major reason why P07A7 code depicts. So, make sure to replace it online so that you don’t have to face any further issues.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

You must perform a technical service bulletin search for your particular vehicle. Advanced diagnostic steps become very vehicle specific and may require the appropriate advanced equipment and knowledge to perform accurately. We include basic steps below but refer to a vehicle year/make/model/powertrain specific repair guide for specific steps for your vehicle. It is very important to follow the basic maintenance procedures accordingly at this point, as far as the transmission's health goes, start at the fluid. Your ATF (Automatic Transmission fluid) should be fully clean, free of debris and also, proper maintenance schedules have to be followed to avoid more defects. If you don’t remember the last transmission has been serviced (i.e. filter+fluid+gasket), it’s a good idea to perform this before continuing. There might be a bit of debris in your oil that is trapped internally. It may only take a simple service, so make sure you are aware of the last A/T service.

While attempting to search the connector/harness for this system, there is a need to find the junction connector. There may be one "master" connector so make sure you are working with the right one by referring to your manual. Make sure that the connector itself is seated properly to guard a fine electrical connection. Now when the connector is situated on the A/T, it may be subject to vibrations due to which the connections might become loose or physically damage them. Not to mention, the possibility of ATF to saturate connectors and wires causing future or present issues. All of us should be fully aware of the overall condition of your vehicle. Rough tires, worn out suspension parts, inaccurate wheels, all of these can and will cause issues in this system and possibly others as well, so even things out, and you may get rid of this code.

Common Mistakes When Diagnosing The P07A7 Code

• Decrease in the transmission fluid level
• Failure in the transmission valve body solenoid
• There can be some faults in the internal transmission
