P2710

Shift Solenoid "F" Intermittent

Severity: High
Driving: Drive only to a garage

The circuit for shift solenoid "F" is faulting intermittently. The transmission drives normally most of the time and then shifts badly or drops into limp mode, usually recovering after a restart.

Possible causes

CommonDebris in the fluid jamming the solenoid
CommonFailed solenoid
CommonCorroded transmission case connector, or fluid wicking into it
CommonLow or degraded fluid
PossibleInternal transmission harness failure
PossibleSticking valve in the valve body bore

What you might notice

Transmission stuck in one gear
Harsh, delayed or flaring shifts
Slipping under load
Missing gears
Check engine light on

What to check, in order

Note whether it only happens hot. A fault that appears after twenty minutes and is gone the next morning points at the internal harness or the solenoid.
Record the freeze frame data - the fluid temperature when the code set is often the most useful clue available.
Check the fluid level and condition first. It is the cheapest check and it explains more transmission complaints than every electrical fault combined.
