A device employed to measure the temperature of transmission fluid as it flows through a vehicle’s transmission system. Such a device often comprises a sensor, wiring, and hardware necessary for installation in-line with existing transmission fluid lines or within a transmission cooler line.
Monitoring transmission fluid temperature is critical for preventing overheating and subsequent damage. Elevated temperatures can degrade fluid, reducing its lubricating properties and leading to premature wear or failure of transmission components. Early detection allows for preventative maintenance and can extend the lifespan of the transmission system.
