P0871 CHEVROLET Description

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