DESCRIPTION
This device is a set of five pressure switches (two normally closed and three normally open), that detect fluid pressure within the valve body passages. The five pressure switches are connected to three signal circuits referred to as range signals A, B, C.
The combination of pressure switch states determine the voltage signal (B+ or zero) on each range signal to the Powertrain Control Module (PCM). These three range signals are then interpreted by the PCM to indicate the transmission range selected. The transmission range fluid pressure switch assembly contains the trans fluid temperature sensor and attached to the control valve body within the transmission.
