OBD-II Code

P2730

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)

$500–$4,000

From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.

P2730 means Pressure Control Solenoid G is electrically stuck on — the TCM sees current flow through the coil even when it's commanding the solenoid off, which means a shorted coil winding, a shorted driver transistor in the TCM, or chafed wiring against ground in the harness.

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.

  1. 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.

  2. 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.

  3. 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.

  4. 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.

P2730 means Pressure Control Solenoid G is electrically stuck on — the TCM sees current flow through the coil even when it's commanding the solenoid off, which means a shorted coil winding, a shorted driver transistor in the TCM, or chafed wiring against ground in the harness. Stuck-on is more serious than open-circuit (P2729) because it usually means the affected clutch element is hydraulically applied when it shouldn't be, which produces bind-up on shifts and can cook the clutch pack quickly if the vehicle is driven.

Cheapest-first ladder

  1. confirm fluid condition (burned fluid here is a sign damage has already happened, and any subsequent repair plan needs to factor in a clutch rebuild on top of the solenoid); ohm the PCS-G coil — should read 8-30 ohms cold (lower end 4-8 ohms typical on 10R80/10L80 designs), and a reading under 3 ohms or a dead short to ground is a condemned solenoid; scope the drive line looking for the TCM cleanly cycling the driver high and low against expected PWM (100-300 Hz, 0.5-1.5 A drive).
  2. If the coil ohms in spec but the line still shows continuous current flow, suspect a chafed conductor in the internal lead-frame shorted to ground.
  3. Caveat: a stuck-on PCS on a 10-speed almost always demands a pan drop plus valve-body access ($400+ in labor before parts), and if fluid color or smell suggests clutch damage, the repair scope expands to a partial rebuild.
  4. Pressure-test and inspect fluid BEFORE quoting a simple solenoid swap.

  • 2017+Ford 10R80 (F-150, Mustang, Bronco, Expedition) is the most common P2730 platform — early-build 10R80s had documented lead-frame harness chafing that produced shorts-to-ground on the G channel, and Ford issued updated lead-frame parts and calibration in 2019-2020 model years.
  • 2017+GM 10L80/10L90 (Silverado, Tahoe, Camaro ZL1, Escalade) shares the 10-speed architecture and shows the same stuck-on pattern from internal harness wear at higher mileage. A handful of other modern automatics use a G-labeled solenoid (some Aisin AWR6B45 variants behind RWD applications, certain Mercedes 9G-Tronic 725 implementations) but field-service P2730 reports cluster heavily on the 10R80/10L80 platforms.

Estimated repair$500 to $4,000.
