Abstract

A controller-assisted, manually shifted transmission system (10) utilizes a shift inhibit mechanism (48) to inhibit out-of-synchronous shifts and unintended disengagement of ratios. An intent to shift (ITS) and target ratio (GRT) are determined from a shift lever position sensor (46) and a force sensor (50).
