ABSTRACT:
A control system for a multiple ratio transmission including two overrunning couplings acting in cooperation with friction clutches and brakes to effect controlled shifts between ratios to reduce inertia torque upon engagement of friction brakes associated with speed ratio downshifts that occur in time-controlled stages following a command for a downshift and for establishing an electronic pressure accumulator effect upon speed ratio upshifts following a command for an upshift.
