A/Trans Manual Shift Shaft Position Switch Assembly
The A/Trans manual shift shaft position switch assembly is a dual sliding hall-effect switch attached to the control valve body within the transmission. The 9 outputs from the switch indicate which position is selected by the transmission manual shaft. Four outputs (A, B, C, P), are range selection inputs to the transmission control module. The five (R1, R2, D1, D2, S) direction selection inputs to the hybrid/EV powertrain control module 1 through the transmission X175 24-way connector. The input voltage at the modules is high when the switch is open and low when the switch is closed. The state of each input is displayed on the scan tool as Internal Mode Switch Range and Internal Mode Switch 2. The Internal Mode Switch Range input parameters represented are transmission range signal A, signal B, signal C and signal P. The Internal Mode Switch 2 parameters represented are transmission direction signal R1, signal R2, signal D1, signal D2 and signal S.
