OBD-II Code
P2717
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)
$250–$1,800
From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
P2717 narrows the P2716 family fault to a specific failure mode: Pressure Control Solenoid D control circuit LOW — the TCM driver is seeing the solenoid command line pulled to ground or near-ground when it should be cycling between 0V and battery voltage under PWM control.
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.

P2717 narrows the P2716 family fault to a specific failure mode
Pressure Control Solenoid D control circuit LOW — the TCM driver is seeing the solenoid command line pulled to ground or near-ground when it should be cycling between 0V and battery voltage under PWM control. The fault modes are: the solenoid coil is internally shorted to ground (the coil winding has bridged to the solenoid case), the harness wire from the TCM driver pin to the solenoid is shorted to chassis ground somewhere between the connector and the solenoid (often where the lead-frame passes through the case connector), or the TCM driver itself has failed shorted-low on that channel (rare but possible on high-mileage TCMs that have run through repeated solenoid coil shorts that took out the driver). Cheapest-first ladder: with the solenoid disconnected at the case connector, key-on, measure resistance from the solenoid driver pin to ground — anything below the coil's spec resistance (8-30 ohms typical for PCS-D) measured between the TCM pin and ground with the solenoid disconnected indicates a wiring-to-ground short, NOT a solenoid; with the harness disconnected from the TCM and from the solenoid, isolate the solenoid-side resistance (8-30 ohms coil-to-coil, infinite resistance coil-to-case-ground — anything less than infinite to the solenoid case is a shorted coil); back-probe the TCM driver pin with the harness reconnected and scope the PWM waveform during a commanded lockup — a healthy driver pulses 0V to 12V at the commanded duty cycle, a stuck-low driver sits at 0V. Before condemning the TCM on a P2717, ALWAYS isolate the solenoid coil itself (drop the pan and check coil-to-case resistance) — a coil that's shorted internally to its own case will take out the TCM driver on the next drive cycle if not replaced, so condemning the TCM first wastes the money and leaves the root cause in the trans.

- 2011-2017Ford F-150/Expedition/Mustang 6R80 is the dominant P2717 platform — the TCC PCS coil ages and develops an internal short to case ground, which then takes out the TCM driver on the same channel if not caught early; Ford issued service updates on early 6R80 solenoid replacement and on TCM replacement when the driver is confirmed failed.
- 2013-2018Ram 2500/3500 with the Aisin AS69RC throws P2717 from internal lead-frame chafe in the trans pan where the lead-frame routes over the valve body — the chafe shorts the PCS-D circuit to case ground.
- 2008-2014GM 6L80/6L90 throws P2717 from internal wiring harness pin-fret and from the PCS coil shorting to ground on high-mileage trucks.
- 2009-2014Chrysler 545RFE/65RFE family throws P2717 from solenoid pack internal failure.
- 2007-2013BMW ZF6HP and ZF8HP-equipped models throw P2717-class codes from mechatronic-unit internal failure (the mechatronic is the integrated TCM + solenoid pack; the failure is usually internal solder-joint fatigue on the TCM substrate).
