Code P2808 Description

The P2808 diagnostic trouble code (DTC) refers to a specific issue with the Pressure Control Solenoid 'G'. This solenoid is responsible for regulating the hydraulic pressure within the transmission system, which in turn controls the shifting of gears. When the PCM (Powertrain Control Module) detects that the performance of the Pressure Control Solenoid 'G' is not within the expected parameters, it triggers the P2808 code. This can lead to various transmission-related issues, such as harsh shifting, delayed shifting, or even transmission slippage. If left unaddressed, this problem can cause further damage to the transmission system, leading to costly repairs or replacement.

  4. Decreased fuel efficiency
  5. Illumination of the Check Engine Light

How to Fix P2808

  1. Perform a diagnostic scan to confirm the P2808 code and pinpoint the exact cause of the issue.
  2. Inspect the transmission fluid level and quality, topping up or replacing as necessary.
  3. Check the wiring and connectors for any damage or corrosion, repairing or replacing as needed.
  4. Test the Pressure Control Solenoid 'G' for proper operation, replacing it if faulty.
  5. Clear the DTC and test drive the vehicle to ensure the issue has been resolved.

Cost to Fix P2808

The cost of repairing a Pressure Control Solenoid 'G' performance issue can vary depending on the specific cause of the problem and the labor rates in your area. In general, you can expect to pay anywhere from $200 to $500 for parts and labor. Keep in mind that additional costs may apply if other components need to be replaced or if there are underlying transmission issues. It's recommended to consult with a professional mechanic for a more accurate estimate based on your vehicle's make and model.

Tech Notes for P2808

When a transmission solenoid malfunction, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. If the transmission fluid is dirty, it's recommended to change the transmission fluid and if possible, remove the transmission pan for further diagnosis. Excessive debris or metal particles on the transmission pan could be an indication that there is a mechanical transmission failure, and that the transmission will need to be rebuilt or replaced.
