ABSTRACT:
A transmission controller includes a rotatable shaft that controls engagement and disengagement of a variable speed clutch. An actuator, such as an electric motor, drives the shaft. The shaft is rotated alternately in the normal and reverse directions by supplying a low level current to such an extent that a clutch transfer mechanism is not operated by the rotation. Rotation stop positions are detected. A play area between the rotation stop positions is calculated and can be used to correct for manufacturing inaccuracies or for wear occurring over time.
