Code P2797 Saturn Description
The P2797 diagnostic trouble code (DTC) for Saturn vehicles refers to the Auxiliary Transmission Fluid Pump Performance. This code indicates that there is an issue with the auxiliary transmission fluid pump, which is responsible for maintaining proper fluid pressure in the transmission system. The pump is crucial for ensuring smooth gear shifts, cooling transmission components, and preventing damage due to lack of lubrication. When this pump malfunctions, it can lead to various problems with the transmission system, affecting the vehicle's overall performance and drivability.
Common Causes of P2797 Saturn
- Faulty auxiliary pump: The pump itself may be defective or worn out, resulting in reduced performance.
- Low transmission fluid level: Insufficient fluid levels can put strain on the pump and cause it to malfunction.
- Clogged transmission filter: A blocked filter can restrict fluid flow to the pump, leading to performance issues.
- Electrical issues: Wiring problems or a faulty control module can prevent the pump from operating correctly.
Symptoms of P2797 Saturn
- Delayed or rough shifting: The transmission may struggle to shift smoothly between gears, leading to jerky movements or delays in acceleration.
- Overheating transmission: A malfunctioning auxiliary pump can cause the transmission to overheat, resulting in potential damage to internal components.
- Transmission slipping: The vehicle may experience slipping gears, making it difficult to maintain speed or acceleration.
- Illuminated warning lights: The check engine light or transmission warning light may come on to indicate a problem with the transmission system.
How to Fix P2797 Saturn
- Diagnose the issue: Use a diagnostic scanner to retrieve the trouble code and pinpoint the exact cause of the problem.
- Inspect the auxiliary pump: Check the pump for signs of damage or wear, and replace it if necessary.
- Check fluid levels: Ensure that the transmission fluid level is adequate and top up or replace as needed.
- Replace the transmission filter: If the filter is clogged, install a new one to prevent further issues.
- Test drive: After completing the repairs, test drive the vehicle to confirm that the transmission is functioning properly.
Cost to Fix P2797 Saturn
The cost of repairing the auxiliary transmission fluid pump performance issue can vary depending on the extent of the damage and the specific parts required. On average, the repair cost for this type of problem can range from $200 to $500, including parts and labor. However, it's important to note that prices may differ based on the location of the repair shop, the make and model of the vehicle, and the type of transmission system.
