Abstract
A vehicle including a device for determining vehicle operational data and for determining distance traveled by the vehicle. A memory is provided for storing the operational data together with the distance traveled as paired values for subsequent diagnostic and maintenance purposes. Signals representative of engine rotational speed, transmission input rotational speed, and torque transmitted by the clutch are sensed for determining clutch performance loss values, and the performance loss values are stored in the memory as paired values along with the vehicle distance traveled.
