P2807 on Toyota: How to Diagnose & Fix
Pressure Control Solenoid "G" Malfunction

P2807 on Toyota by model: symptoms, diagnosis and fix
Early-production 4th-generation Tacomas with the 8-speed automatic transmission can suffer internal failure of the torque converter clutch actuator or pressure-control solenoids, often at very low mileage (some under 15,000 miles). Owners report harsh 1st-to-3rd-gear jerking, slipping, lunging, the truck dropping into neutral or getting stuck in gear, and sudden loss of drive. Toyota traced the cause to a stuck pressure-control solenoid actuator or torque-converter-clutch actuator (with manufacturing debris suspected) and issued TSB T-SB-0076-24, superseded by T-SB-0094-24 which added the Hybrid (i-FORCE MAX). The fix is not a calibration but a complete transmission and torque-converter replacement.
Common Symptoms
- Harsh or jerky 1st-to-3rd gear shifting
- Transmission slipping or lunging
- Truck drops into neutral or gets stuck in gear
- Loss of power / sluggish acceleration
- Check engine light with transmission DTCs
- Failure often within first 10,000-15,000 miles
How to Fix
Have the dealer scan for the listed DTCs and perform the transmission and torque-converter replacement under TSB T-SB-0076-24 / T-SB-0094-24. Repairs are covered under Toyota's 60-month/60,000-mile powertrain warranty at no cost. If the dealer claims they cannot replicate the symptom, document occurrences (dates, mileage, video) and request the field-fix bulletin be applied; escalate to Toyota corporate (1-800-331-4331) if denied.
Call to confirm they can assess your vehicle and perform the stated work. Search results do not confirm qualification, eligibility or coverage.

Frequently asked questions
What does P2807 mean on a Toyota?
P2807 stands for "Pressure Control Solenoid "G" Malfunction." The transmission control module detected a fault with pressure control solenoid 'G', one of the solenoid-operated valves that meters line pressure to a specific clutch or band in the automatic transmission. Toyota's Tacoma AC8 bulletin lists it as P280771, 'Pressure Control Solenoid G Actuator Stuck': the module commanded the solenoid and the resulting pressure did not follow, indicating the valve is hydraulically stuck rather than electrically open or shorted. On Toyota it is documented across 1 model: Tacoma.
What are the most common causes of P2807?
The most common causes of P2807 are: Pressure control solenoid 'G' stuck open or stuck closed, Debris or varnish in the valve body from degraded fluid, Low transmission fluid level or wrong fluid specification, Wiring, connector, or internal harness fault to the solenoid, Internal transmission hydraulic failure requiring unit replacement. The specific cause varies by vehicle.
How much does it cost to fix P2807 on a Toyota?
Repair costs vary widely with the root cause and Toyota model; each issue on this page carries its own estimate where one is published.
