ABSTRACT:
An automatic transmission control system includes a shift valve having a valve body, a spool, a sleeve, a plunger and a return spring. An area of the plunger is acted on by a throttle pressure and is smaller than an area of a land acted on by the throttle pressure. Accordingly, the spool is movable against the throttle pressure to make a upshift when the governor pressure is over a predetermined value in relation to the throttle pressure.
