P2810
Pressure Control Solenoid G Electrical
Transmission controls
Generic OBD-II
Medium
What it means
P2810 means the transmission controller detected an electrical fault — an open or short — in pressure control solenoid G. This solenoid regulates hydraulic pressure for shifting, so a fault typically shows up as harsh or slipping shifts and can trigger limp mode. The cause is usually the solenoid itself or its wiring, though low or dirty fluid can contribute.

Can I keep driving? Often limited — a bad pressure-control solenoid can cause harsh shifts or push the transmission into limp mode, so avoid hard driving until it's fixed.
Common symptoms
What you'll notice
- Check-engine light on
- Harsh, erratic, or slipping shifts
- Reduced-gear limp mode
- Poor engagement or flare between gears
Common causes
Most likely first
- Faulty pressure control solenoid G (electrical open/short)Likely
- Open, shorted, or corroded solenoid wiring/connectorCommon
- Low or dirty transmission fluidCommon
- Contaminated or sticking valve body passageLess often
- TCM driver fault (rare)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame and confirm the electrical fault on solenoid G.
- Check transmission fluid level and condition.
- Inspect the solenoid connector and harness for damage or corrosion.
- Measure the solenoid resistance and compare to spec for an open or short.
- Replace the solenoid (or valve body) if it's out of spec, then clear and re-test.
FAQ
Quick answers
Is it safe to drive with P2810?+
Keep it gentle. Erratic pressure control can damage clutches over time, and the transmission may drop into limp mode. Repair it soon.
Can I just clear P2810?+
It comes back while the solenoid or its circuit is faulty. Fix the electrical cause first.
