P2737 — Pressure Control Solenoid "F" Control Circuit Range/Performance

powertrain (engine/transmission)

Is it safe to drive?

Drive with caution Drive only if the transmission still shifts predictably, and avoid highway speeds. Driving with slipping or limp mode accelerates internal wear — every kilometre can add to the final repair bill.

How to diagnose with an OBD scanner

  1. Read the code and freeze frame Connect an OBD2 scanner, confirm P2737 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
  3. Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the automatic transmission control for damage, corrosion, chafing or poor contact.
  4. Subsystem check Compare the pressure control solenoid "F" control live reading against a known-good reference (specification or a correlated sensor) under the conditions from the freeze frame.
  5. Subsystem check Check transmission fluid level and condition — dark, burnt fluid points to internal wear.
  6. Subsystem check Read transmission-specific codes and live data (solenoid states, input/output speed) with a capable scanner.
  7. Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2737 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2737 (parts and labor, USD, independent shop rates): Replace a shift solenoid: $300–$800; Transmission rebuild or replacement: $2,500–$5,500; Valve body repair or replacement: $700–$1,500; Transmission fluid service: $150–$350. Overall, fixing P2737 usually costs between $150 and $5,500. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

How do I diagnose P2737 myself?

Start with a scan: confirm P2737, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the pressure control solenoid "F" control, and verify the suspect component against live data before buying parts.

What is the most common cause of P2737?

The most common causes are: failed shift or pressure control solenoid, wiring or connector faults in the valve body harness, valve body wear.

What are the symptoms of P2737?

Drivers most often notice: Check Engine or transmission warning light on, harsh or delayed shifting, no movement in severe cases, transmission stuck in one gear (limp mode).

Will P2737 clear itself?

Sometimes P2737 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

How much does it cost to fix P2737?

Replace a shift solenoid — $300–$800; Transmission rebuild or replacement — $2,500–$5,500; Valve body repair or replacement — $700–$1,500; Transmission fluid service — $150–$350. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

What does P2737 mean?

When P2737 appears on a scan, it means the control module has flagged a problem in the automatic transmission control: pressure control solenoid "F" control circuit range/performance. The fault sits in the powertrain (engine/transmission) group of the OBD2 standard.

“Range/performance” means the signal from the pressure control solenoid "F" control is electrically valid but does not match what the module expects for current operating conditions. The wiring is usually intact; the problem is a degraded component, a drifted sensor or a mechanical fault upstream.

This code does not appear from a single bad reading: the module must see the fault condition repeat under defined operating conditions before it turns on the warning light. The freeze frame captured with P2737 — engine load, rpm, temperature, speed — tells you exactly when the problem occurs, so reproduce those conditions when testing.

Common symptoms of P2737

  • Check Engine or transmission warning light on
  • harsh or delayed shifting
  • no movement in severe cases
  • transmission stuck in one gear (limp mode)
  • shuddering at highway speed
  • slipping between gears

What causes P2737?

  • degraded or drifting pressure control solenoid "F" control
  • mechanical fault that the sensor correctly reports
  • incorrect calibration after a module update or battery disconnect
  • low or degraded transmission fluid
  • wiring or connector faults in the valve body harness
  • valve body wear
  • failed shift or pressure control solenoid
  • faulty transmission speed sensor
  • internal mechanical wear (clutches, torque converter)

How to diagnose P2737

  1. Connect an OBD2 scanner, confirm P2737 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
  3. Visually inspect the wiring harness and connectors related to the automatic transmission control for damage, corrosion, chafing or poor contact.
  4. Compare the pressure control solenoid "F" control live reading against a known-good reference (specification or a correlated sensor) under the conditions from the freeze frame.
  5. Check transmission fluid level and condition — dark, burnt fluid points to internal wear.
  6. Read transmission-specific codes and live data (solenoid states, input/output speed) with a capable scanner.
  7. Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2737 does not return.
