  • Method to determine the remaining useful life of automatic transmission fluid
    Patent number: 5777211
    Abstract: A method of determining the remaining useful life of automatic transmission fluid used in an automatic transmission or transaxle is provided. A multiplicity of vehicles having the same type of automatic transmission or transaxle are monitored and data on factors bearing on the useful life of automatic transmission fluid are collected. Weighted constants are derived for each factor. The automatic transmission controller is then programmed to monitor the operation of the automatic transmission or transaxle and collect data on the factors that bear on the useful life of the automatic transmission fluid. Based on the collected data and weighted constants, the remaining useful life of the automatic transmission fluid is determined.
