ABSTRACT:
The back-pressure which is supplied to a back-pressure chamber of a servo release accumuator associated with friction elements which are engaged and disengaged, respectively during an upshift, is reduced by a solenoid controlled valve which connects the back-pressure chamber with a drain when the throttle valve of an engine associated with the transmission is sensed as being fully closed.
