P2700 OBD-II Trouble Code: Transmission Friction Element "A" Apply Time Range/Performance

diagnostic check engine light

P2700 code definition

The P2700 trouble code detects a problem with the transmission friction element application.

What the P2700 code means

The P2700 code is a generic OBD-II trouble code that notes a fault in the transmission friction element A application. The powertrain control module (PCM) keeps track of both the input RPM signal and the output RPM signal, and when it detects an abnormality between these two signals the P2700 code may be triggered.

What causes the P2700 code?

Potential causes of the P2700 code are:

What are the symptoms of the P2700 code?

The P2700 code will usually be accompanied by an illuminated check engine soon Warning Light on the instrument panel. It is common for the transmission have issues, such as harsh shifting, slippage, and possibly an inability to change gears. The transmission may also activate the “limp-in” mode.

How does a mechanic diagnose the P2700 code?

The P2700 code will be diagnosed with the aid of an OBD-II trouble code scanner. A trustworthy technician can use the scanner to view the freeze frame data and assess the P2700 code. Additional trouble codes should also be checked for, and if any are present, they should be addressed in the order in which they are displayed on the scanner. The mechanic will then reset the trouble codes, restart the vehicle, and use the scanner to see if the P2700 code remains detected. If it does not, then it was most likely triggered erroneously, or is the result of an intermittent error.

If the code returns following the reset, the mechanic will visually inspect the electrical components in the transmission and the PCM. Shorted or loose wires, open or corroded connectors, and blown fuses should all be replaced. If any of the electrical components show signs of being leaked on, or otherwise damaged by a faulty component in the system, further inspection will be required. The transmission fluid should then be checked, and dirty fluid should be flushed out and replaced. If the fluid levels are low, an inspection for leaks will be necessary. If the fluid is severely contaminated, then the transmission likely has experienced damage that will require a rebuild or replacement. The transmission pump will also need to be checked.

The transmission itself will then need to inspected. If there are no signs of the transmission overheating, then the problem is likely a faulty input or output speed sensor. If there are signs of overheating, the transmission may need a partial or full rebuild.

After any component has been replaced, the mechanic will need to reset the trouble codes, restart the vehicle, and again check for the presence of the P2700 code. This helps the technician know when the problem has been fixed.

Common mistakes when diagnosing the P2700 code

The most frequently made diagnostic mistake with this code comes from a failure to follow the OBD-II diagnosis protocol. It is very important that mechanics abide by the protocol exactly, to make sure that all inspections and repairs are both thorough and efficient.

It is fairly common for transmission fluid leaks that have damaged the transmission to be repaired without checking the rest of the system, or retesting the trouble codes. This can result in severe damage to the transmission being overlooked.

How serious is the P2700 code?

The drivability of a vehicle with a detected P2700 code can vary greatly. In some cases, there will be no noticeable performance problems, while other times transmission issues may be noticeable, or even prevent the car from being driven. Even if the car is driving normally, serious damage can occur to the transmission if the P2700 code is not addressed, so an inspection and repair should be scheduled as soon as the code is detected.

What repairs can fix the P2700 code?

Some repairs for the P2700 code include:

Additional comments for consideration regarding the P2700 code

It is very rare that the P2700 trouble code signals a defective PCM. However, if the PCM does need to be replaced, it will also need to be reprogrammed.

If the transmission has only overheated a few times, it may not require a rebuild or replacement.
