Abstract: A system for pressurizing transmission control elements includes an accumulator for containing pressurized fluid, first and second check valves, a booster valve supplied with accumulator pressure, and an actuator that causes the booster valve to open a fluidic connection between the accumulator and the control elements through the check valves in response to an engine restart signal.

Abstract: A control valve for an automatic transmission includes a valve body and a solenoid module. The body has a chamber, control pressure port, exhaust port, and reference surface. Metering edges are formed in the body at the control port. A spring transmits force between first and second spools in the chamber. The solenoid module has a pin for displacing the first spool and is located by contact with the reference surface. The solenoid module also has a first stop surface limiting pin movement and a second stop surface contacting the reference surface.
