If your vehicle has a P2707 DTC, it means that the computer has detected that one of the shift solenoids is not performing correctly, or it’s stuck in the off position. This will seriously impede your vehicle’s performance, by preventing shifts from taking place when they need to.

How Serious is the Code?
Having a P2707 diagnostic trouble code is a very serious problem, and it can cause serious drivability issues. For example, transmission can refuse to shift, overheat or slip. Needless to say, these transmission problems can impact the safety of your vehicle.
Symptoms
Symptoms of a P2707 include:
- Unusually firm shifts
- Slipping between gears

- Limp mode
Causes
- Dirty transmission fluid
- Low transmission fluid
- Dirty transmission filter
- Damaged wiring/connectors
- Blocked hydraulic channels
- Failed shift solenoid

How to Diagnose the Code?
In order to diagnose a P2707 OBDII diagnostic trouble code, mechanic should first check the level and condition of the transmission fluid. Dirty transmission fluid can cause hydraulic passages inside the valve body to clog, which can prevent this solenoid from performing correctly. Manufacturer TSB’s also need to be researched, and the wiring and connectors on the transmission wiring harness should also be inspected. If no issues are found, further diagnostic tests will need to be performed on the solenoids and valve body.
