P2807 - Pressure Control Solenoid 'G' Stuck On
The P2807 code indicates that the Transmission Control Module (TCM) has detected the pressure control solenoid 'G' is stuck in the 'on' position. This solenoid regulates hydraulic pressure to the transmission clutches and bands. When stuck on, it can cause harsh shifting, slipping, or transmission overheating. The issue is often electrical (wiring, connector) or mechanical (solenoid failure, debris).
1. Most Common Causes
- Faulty pressure control solenoid 'G'
- Damaged wiring or connector to solenoid
- Low transmission fluid level or dirty fluid
- Internal transmission mechanical failure
2. Symptoms You Will Notice
- Check Engine Light on
- Harsh or delayed shifts
- Transmission slipping
- Transmission overheating
3. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Check transmission fluid level and condition.
Step 3: Inspect wiring and connector for damage or corrosion.
Step 4: Test solenoid resistance and operation with a multimeter.
Step 5: Perform a transmission pressure test to confirm solenoid function.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as it can cause transmission damage. Limited driving to a repair shop is acceptable if shifting is not severely affected.
How much does it cost to fix?▼
Repair costs range from $200 to $600, depending on whether the solenoid is replaced individually or as part of a transmission service. Labor is typically $100-$200, and parts $50-$150.
