Transmission Fluid Pressure (TFP) Manual Valve Position Switch Assembly

WARNING: This page is about a different variant/trim than selected.

D3 fluid is routed to the TFP manual valve position switch and opens the normally closed D3 fluid pressure switch. The combination of the opened D3 switch and the closed D4 switch signals the PCM that the transmission is operating in Manual Third.
