Abstract

See full text

A system for managing a lockup clutch in an off-road truck includes an engine, a transmission and a torque converter coupled between the engine and the transmission. The torque converter has a lockup clutch that when engaged directly couples the engine to the transmission. The system also includes a transmission controller that disengages the lockup clutch responsive to sensing a missed shift in the transmission, and subsequent to sensing a completed shift, sets an engine speed limit corresponding to a gear associated with the completed shift, and reengages the lockup clutch.
