Abstract

A system and method are disclosed for controlling a shift even in a transmission (14) wherein a shift actuator (30,48) develops a force to effect the engagement of a clutch collar and a gear. The method comprises detecting when a non-fully engaged condition of the clutch collar and the gear occurs, indicating either a tooth butt or torque lock condition, and then pulsing the shift actuator (30,48), when the non-fully engaged condition is detected, between a relatively low force and a relatively high force to disturb the clutch collar and the gear out of the non-fully engaged condition, The detecting step comprises examining either the axial position of the clutch collar or the axial position of a shift rail operatively connected to the clutch collar with a rail position sensor (43). Preferably, a signal having a modulated pulse width and a frequency of between about 5 and 20 Hertz is sent to the shift actuator. The system which embodies this method is disclosed in the forms of an automated mechanical transmission having sliding clutch collars (122,124,126) and a transmission system having a standard friction master clutch interposed between the engine and the transmission.
