P2807 — Pressure Control Solenoid "G"

P2807 — Pressure Control Solenoid "G". A fault in the automatic transmission control. Short, gentle driving to a shop is usually possible. Typical causes: valve body wear, failed shift or pressure control solenoid, wiring or connector faults in the valve body harness.

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 P2807 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 Check transmission fluid level and condition — dark, burnt fluid points to internal wear.
  5. Subsystem check Read transmission-specific codes and live data (solenoid states, input/output speed) with a capable scanner.
  6. Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2807 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2807 (parts and labor, USD, independent shop rates): Transmission fluid service: $150–$350; Valve body repair or replacement: $700–$1,500; Replace a shift solenoid: $300–$800; Transmission rebuild or replacement: $2,500–$5,500. Overall, fixing P2807 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

Will P2807 clear itself?

Sometimes P2807 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.

What is the most common cause of P2807?

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

How much does it cost to fix P2807?

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

What are the symptoms of P2807?

Drivers most often notice: shuddering at highway speed, harsh or delayed shifting, slipping between gears, Check Engine or transmission warning light on.

What does OBD2 code P2807 mean?

P2807 — Pressure Control Solenoid "G". A fault in the automatic transmission control. Short, gentle driving to a shop is usually possible. Typical causes: valve body wear, failed shift or pressure control solenoid, wiring or connector faults in the valve body harness.

What does P2807 mean?

The engine control module sets P2807 when it detects a fault in the automatic transmission control. In practical terms: pressure control solenoid "G". The code belongs to the powertrain (engine/transmission) group of OBD2 codes.

The module monitors this system continuously while driving. When readings fall outside the expected range for a defined number of drive cycles, it stores P2807 and switches on the warning light. Freeze frame data saved with the code shows the exact conditions — rpm, load, temperature, speed — at the moment the fault was detected, which is the best starting point for diagnosis.

Common symptoms of P2807

  • shuddering at highway speed
  • harsh or delayed shifting
  • slipping between gears
  • Check Engine or transmission warning light on
  • no movement in severe cases

What causes P2807?

  • low or degraded transmission fluid
  • valve body wear
  • wiring or connector faults in the valve body harness
  • internal mechanical wear (clutches, torque converter)
  • faulty transmission speed sensor
  • failed shift or pressure control solenoid

Can you drive with P2807?

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.
