What Does P2810 Mean?
The Transmission Control Module (TCM) has detected an electrical fault in the pressure control solenoid 'G' circuit. This indicates a general electrical problem affecting the solenoid's ability to regulate transmission line pressure.
Common Causes
35%
Failed pressure control solenoid 'G' with internal short or open circuit
30%
Damaged wiring harness or corroded connectors in solenoid circuit
15%
Low transmission fluid causing solenoid overheating and failure
12%
Failed Transmission Control Module (TCM)
8%
Internal transmission mechanical damage affecting solenoid operation
Diagnostic Steps
1
Step 1: Check transmission fluid level and condition; top off or replace if low or burnt
2
Step 2: Inspect transmission wiring harness and connectors for damage, corrosion, or loose pins
3
Step 3: Measure resistance of pressure control solenoid 'G' and compare to manufacturer specifications (typically 3-30 ohms)
4
Step 4: Test solenoid control circuit voltage and ground with key on, engine running using multimeter
5
Step 5: Monitor live data for solenoid command vs actual pressure readings to verify TCM functionality
Estimated Repair Cost
$250 - $800
Parts + labor, varies by vehicle and location
The Transmission Control Module (TCM) has detected an electrical fault in the pressure control solenoid 'G' circuit. This indicates a general electrical problem affecting the solenoid's ability to regulate transmission line pressure.
The most common cause of P2810 (Pressure Control Solenoid "G" Electrical) is: Failed pressure control solenoid 'G' with internal short or open circuit
Typical repair costs for P2810 range from $250 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle may experience harsh shifting, transmission slipping, or enter limp mode limiting speed. Continued driving may cause severe transmission damage.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2810 to identify the root cause.
