Abstract
A method of controlling a transmission and engine during a coasting downshift is particularly suited to transmission arrangements exhibiting strong inertia coupling. During the inertia phase of the downshift, a third clutch such as a torque converter bypass clutch is modulated to control output torque. Simultaneously, engine torque is modulated to control engine speed. The resulting control scheme is only semi-coupled.
