DTC Descriptor
DTC P0897
- Transmission Fluid Life

Circuit/System Description

Transmission fluid life is determined by monitoring transmission fluid temperature over a period of time. The transmission control module (TCM) calculates transmission fluid life based on a set of temperature ranges stored in TCM memory.

Conditions for Running the DTC

No TFT DTC P0712

Conditions for Setting the DTC

The calculated transmission oil life remaining is less than 10 percent.
