Code P079C Description
The diagnostic trouble code P079C indicates that the Transmission Friction Element 'C' Slip has been detected. This means that there is an issue with the friction element within the transmission that is causing it to slip, leading to potential performance issues with the vehicle. The transmission friction elements are responsible for engaging and disengaging various gears within the transmission to allow for smooth shifting and optimal performance. When one of these elements slips, it can result in erratic shifting, decreased fuel efficiency, and potential damage to other transmission components.
Common Causes of P079C
- Worn or damaged friction elements within the transmission
- Low transmission fluid levels or dirty transmission fluid
- Faulty transmission solenoid
- Electrical issues within the transmission control module
- Mechanical damage to the transmission components
Symptoms of P079C
- Erratic shifting or difficulty shifting gears
- Delayed engagement when shifting from park to drive or reverse
- Transmission slipping or jerking during acceleration
- Decreased fuel efficiency
- Illumination of the Check Engine Light
How to Fix P079C
- Perform a diagnostic scan to confirm the P079C code and identify any other related codes.
