P2714 means the transmission control module determined that Pressure Control Solenoid D (PCS-D) is not responding correctly - specifically that it appears to be stuck in the off position or its output pressure doesn't match what the TCM commanded. On most 6-speed and 8-speed transmissions, PCS-D controls pressure for higher gears (5th, 6th, or higher), making this primarily a highway driving problem.
Which Gears Does PCS-D Control?
The exact gear assignment for each pressure control solenoid varies by transmission design. On common applications:
- GM 6L80/6L90: PCS-D is associated with C5 clutch, which is used in 4th, 5th, and 6th gears
- Ford 6R80: Similar higher-gear association
- Chrysler/ZF 8-speed variants: PCS-D typically affects 5th or 6th gear engagement
The practical implication: P2714 symptoms often appear during highway driving - when the transmission needs to engage those higher gears - and may not be noticeable in city driving where the transmission rarely reaches 5th or 6th.
Common Causes of P2714
- Failed PCS-D solenoid: The solenoid's internal components wear or the valve sticks in the off position. More common on high-mileage vehicles where solenoids have cycled millions of times.
- Contaminated fluid: Varnish from degraded ATF coats the solenoid valve, preventing full travel. P2714 is more common on vehicles without regular fluid changes.
- Wiring or connector fault: Broken wire, corroded connector, or resistance too high in the solenoid circuit.
- Low line pressure: If overall line pressure is insufficient, PCS-D cannot apply the commanded clutch pressure even if the solenoid is functional. P2714 combined with P0868 (pressure low) suggests this scenario.
- Solenoid pack failure: On transmissions where all solenoids are integrated into a single pack (common on GM and some Ford applications), PCS-D failure is addressed by replacing the entire pack.
Symptoms of P2714
- Check engine light with P2714 stored
- Slipping or absence of 5th or 6th gear (depending on application) - may feel like the transmission "won't go into overdrive"
- Poor fuel economy at highway speed (transmission running in a lower gear than intended)
- Limp mode on some vehicles
- Companion codes: P0700, P2715, P0868
