P2808: Pressure Control Solenoid 'G' Performance/Stuck Off
The P2808 code indicates that the Transmission Control Module (TCM) has detected a malfunction in the pressure control solenoid 'G', which is responsible for regulating hydraulic pressure within the transmission. The solenoid is commanded to a specific duty cycle, but the TCM detects that the actual pressure response is not within expected parameters, suggesting the solenoid is stuck in the off position or performing poorly. This can lead to harsh or delayed shifts, slipping, or transmission overheating.
01. Most Common Causes
- Faulty pressure control solenoid 'G'
- Low or contaminated transmission fluid
- Wiring or connector issues in the solenoid circuit
- Internal transmission mechanical failure
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or delayed gear shifts
- Transmission slipping or overheating
- Reduced fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Check transmission fluid level and condition; top off or replace if necessary.
Step 3: Inspect wiring and connectors to the pressure control solenoid for damage or corrosion.
Step 4: Test solenoid resistance and operation using a multimeter and scan tool; replace if out of spec.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as the transmission may slip or overheat, leading to costly internal damage. Seek repair promptly.
How much does it cost to fix?▼
Repair costs typically range from $200 to $600, including parts and labor, depending on the vehicle and whether the solenoid is replaced individually or as part of a valve body assembly.
