Abstract
A speed ratio shaft control for multiple ratio vehicle transmission has controlled release of an off-going transmission clutch and controlled engagement of an on-coming transmission clutch during a speed ratio upshift, at least one clutch being a friction torque establishing clutch. A controller, using shift-timing software strategy, actively manages in real time a clutch torque level for each clutch so that transient torque disturbances in a transmission torque output shaft are mitigated.
