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 1 (PS1) monitors shift solenoid valve 1 (SS1) positioning and relays it to the transmission control module (TCM). When PS1 is in the open state, SS1 should be in the destroked position.
