P2807
Pressure Control Solenoid G
Transmission
Generic OBD-II
Medium
What it means
P2807 flags a fault with transmission pressure control solenoid G, which regulates hydraulic pressure for shifting or clutch apply. A fault typically shows up as harsh shifts, slipping, or a limp-mode fallback rather than a no-start. Common causes are low or dirty fluid, a failed solenoid, or its wiring — check fluid and the electrical circuit before suspecting internal damage.
Medium
Can I keep driving? Often driveable but degraded — expect harsh shifts or slipping and possibly limp mode; prolonged slipping can wear the transmission, so address it soon.
Common symptoms
What you'll notice
- Check-engine light on
- Harsh, delayed, or flaring shifts (shift shock)
- Transmission slipping or holding a gear
- Transmission enters limp/failsafe mode
Common causes
Most likely first
- Low or degraded transmission fluid affecting hydraulic pressureLikely
- Faulty pressure control solenoid GCommon
- Open, shorted, or corroded solenoid wiring/connectorCommon
- Debris or wear in the valve body sticking the solenoid or valveLess often
- Faulty transmission control module (least likely)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and check transmission fluid level and condition first — low or burnt fluid alone can set this.
- Inspect the solenoid connector and wiring for corrosion, chafing, or loose pins.
- Measure the solenoid's resistance against spec; replace it if out of range.
- If electrical checks pass, inspect the valve body for debris or a sticking valve. Clear and road-test.
FAQ
Quick answers
Is it safe to drive with P2807?+
Short trips are usually possible, but harsh shifting or slipping can worsen and damage the transmission over time. Get it checked promptly.
Can I just clear P2807?+
It returns unless the solenoid, wiring, or fluid issue is fixed. Address the cause, then clear and confirm.
