P2710 OBD-II Trouble Code: Shift Solenoid F Interm

check engine light

P2710 code definition

If the PCM detects an abnormality in a shift solenoid, the P2710 code will be stored to indicate the error. This error code specifically relates to a solenoid class F, and shows that the abnormality has been intermittently detected.

What the P2710 code means

Shift solenoids are part of the transmission, and manage the transfer of hydraulic fluid between circuits. This is necessary to speed up, slow down, optimize fuel efficiency, and ensure that a vehicle performs at an optimal level. If the solenoid function returns an abnormal voltage level compared to the manufacturer’s specifics, the PCM will store the P2710 code.

What causes the P2710 code?

The most common cause of the P2710 code is also the simplest: a faulty shift solenoid. However, there are other causes behind this code that may include:

  • Blocked internal transmission fluid passages
  • Low transmission fluid
  • Dirty transmission fluid
  • Mechanical internal transmission failure
  • Faulty TCM or PCM

What are the symptoms of the P2710 code?

In some cases, there may be no symptoms preceding the P2710 code at all. In others, however, symptoms can include an inability to shift into or out of a certain gear, harsh shifting, overheating transmission or transmission slippage, and decreased fuel efficiency. The Check Engine Light will be illuminated, and there may be other codes related to the performance of the shift solenoids stored with the P2710 code.

How does a mechanic diagnose the P2710 code?

After verifying the code with an OBD-II scanner, the mechanic should begin addressing any issue related to transmission with an inspection of the transmission fluid. If the fluid is too low, or is dirty, these issues need to be addressed. If transmission fluid is very dirty, the entire system may need to be flushed, and a new torque converter may need to be installed.

The next step is to look for shortened or burned wiring or other electrical components, and to replace any that are necessary. Before this, however, the mechanic should be sure to clear the P2710 code from the PCM, and perform a retest, to ensure that the clean transmission fluid did or did not fix the issue. This step should be performed after every potential fix, to narrow down the options till the true cause is found and addressed.

Common mistakes when diagnosing the P2710 code

Because the shift solenoid is so often to blame for the P2710 code, this part is frequently replaced in error, when the shift solenoid circuit was actually to blame. It’s important to do a thorough diagnostic procedure that eliminates the possibility of electrical error before replacing any parts.

How serious is the P2710 code?

Because this code relates directly to the system that controls acceleration, deceleration, and shifting into and out of gears, the P2710 represents a very serious issue that should be addressed right away. If the issue goes un-repaired, it will most likely affect the performance and fuel economy of a vehicle, and may lead to the inability to operate a vehicle safely.

What repairs can fix the P2710 code?

There are many repairs that could be necessary to fix the issue behind the P2710 code. These repairs may include:

  • Repair or replace faulty shift solenoid.

  • Repair or replace any open, shorted, burnt, corroded, or otherwise faulty electrical components.

  • Replace the torque converter.

  • Repair or replace a defective pump.

  • Repair or replace faulty electronic pressure regulator.

  • Clear any blockages in internal transmission fluid passages.

  • Refill low transmission fluid.

  • Clean dirty transmission fluid and flush system.

  • Diagnose and repair mechanical internal transmission failure.

  • Diagnose and repair issues causing related codes to be stored in the PCM.

  • Replace a faulty TCM or PCM in rare cases.
