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.
