OBD-II Code
P2727
Severity
Not yet reviewed
Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.
Can you drive it
We cannot say
Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.
Indicative cost (USD)
$300–$3,400
From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
P2727 means Pressure Control Solenoid F's control circuit is operating outside the expected range/performance window — the TCM sees current flow but the relationship between commanded duty cycle and measured current, or between commanded pressure and observed hydraulic effect, is wrong.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then follow the diagnostic notes further down this page, in the order they are written.
They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

P2727 means Pressure Control Solenoid F's control circuit is operating outside the expected range/performance window — the TCM sees current flow but the relationship between commanded duty cycle and measured current, or between commanded pressure and observed hydraulic effect, is wrong. This is one step subtler than P2720 (open circuit) and one step less specific than the stuck-on/stuck-off codes; it usually means the solenoid is still electrically alive but its hydraulic response is degraded or its coil is drifting out of spec.
Cheapest-first ladder
- ohm the PCS-F coil cold (8-30 ohms typical depending on application — verify the FSM spec for the specific platform); scope the drive waveform looking for clean PWM at the calibrated frequency (100-300 Hz) with current ramping cleanly between 0.5 A low and 1.5 A high; check for voltage drop across the harness between TCM and solenoid (less than 0.2 V drop end-to-end on a healthy circuit); then mechanical line-pressure test to see whether commanded pressure (50-260 psi across the operating range) matches what the gauge actually reads.
- A solenoid that drives current correctly but doesn't move pressure proportionally usually has a stuck valve in its hydraulic stage or wear in the regulator bore the solenoid feeds.
- Caveat: PCS range/performance codes mean the solenoid is alive but the hydraulic output isn't matching the electrical command — could be the solenoid (cheapest), a worn bore in the valve body the solenoid actuates (medium, Sonnax sleeve kit territory), or worn clutch packs downstream causing a pressure-feedback fault (expensive).
- Pressure-test BEFORE teardown.

- 2007-2014GM 6L80/6L90 throws P2727 most often from worn actuator-feed-limit valve bores in the valve body — the PCS-F is electrically fine but the bore it feeds has lost its sealing diameter, so commanded pressure doesn't materialize at the clutch pack. Sonnax oversize sleeve kits are the standard shop fix.
- 2011+Ford 6R80 sees P2727 from lead-frame corrosion changing the effective resistance on the PCS-F circuit.
- 2009+ZF 8HP electro-hydraulic mechatronic module throws P2727 from mechatronic sleeve leaks contaminating the internal connector; mechatronic rebuild required.
- 2013+Aisin AS69RC throws P2727 when the line-pressure regulator valve in the pump body wears beyond the solenoid's authority range — Aisin offers a service kit for this.
Estimated repair$300 to $3,400.
