Description
The 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 increment. The rate at which the counter increments depend on the temperature range in which the transmission is currently operating in. The higher the temperature range, the faster the counter increments. As the count increment, the TCM will begin to decrease the fluid life percentage from 100, high fluid life, to 0, low fluid life. If the TCM detects a calculated transmission oil life of 10 percent or less, then Diagnostic Trouble Code (DTC) P0897 sets.
