Solenoid Relay Valve
WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
3rd gear band apply (46) fluid also passes through orifice #30 and, together with spring force, overcomes solenoid modulator (9) fluid pressure and moves the solenoid relay valve to the released position. This allows 1-2 reverse clutch (39) fluid to exhaust through the B5 control 2 (38) fluid circuit.
