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. As the vehicle is driven, a counter increments. The rate at which the counter increments, depends on the temperature range in which the transmission is currently operating. The higher the temperature range, the faster the counter increments. As the counts increment, the TCM will begin to decrease the fluid life percentage from 100, high fluid life, to 0, low fluid life.
• | No Transmission Fluid Overtemperature DTC P0218. |
• | No TFT DTCs P0711, P0712, or P0713. |
The calculated transmission oil life remaining is 10 percent or less.
• | DTC P0897 is a Type C DTC. |
• | CHANGE TRANSMISSION FLUID displays on the driver information center (DIC). |
DTC P0897 is a Type C DTC.
Inspect the transmission cooling system for possible blockage and restrictions.
