Abstract
A system and a method for monitoring a lubricant in a transmission are provided. The system comprises a first speed sensor, a temperature sensor, and a processing unit. The first speed sensor is positioned adjacent a first clutch, which forms a portion of the transmission. The first speed sensor is configured to detect a rotational difference between portions of the first clutch. The temperature sensor is disposed within the transmission. The temperature sensor is configured to measure a temperature of the lubricant. The processing unit is in communication with the first speed sensor and the temperature sensor. In response to information from the first speed sensor and the temperature sensor, the processing unit determines a condition of the lubricant used in the transmission.
