The pressure switch manifold (PSM) is a multiple-switch assembly made up of 3 normally open (N/O) and 1 normally closed (N/C) pressure switches. The pressure switch 3 (PS3) monitors shift solenoid valve 3 (SS3) positioning and relays it to the transmission control module (TCM). When PS3 is in the open state, SS3 should be in the destroked position.
