Code P0761 2015 GMC Sierra Description

The transmission fluid pressure switch, also known as the pressure switch manifold, is a multiple switch assembly made up of 3 normally open pressure switches and 1 normally closed pressure switch. Pressure switch 1 monitor shift valve 1 positioning, pressure switch 2 monitors shift valve 2 positioning and pressure switch 3 monitors shift valve 3 positionings. The normally open pressure switches 1–3 communicate the positioning to the Transmission Control Module (TCM). The position of shift valves 1–3 is controlled by 3 normally closed shift solenoid valves 1–3. When energized, the shift solenoid valves directly control the main pressure to shift valve 1, 2, or 3, which strokes the shift valve. When the shift valve is stroked, an exhaust passage is blocked and fluid pressure to the pressure switch increases. The Diagnostic Trouble Code (DTC) will be set if the shift solenoid valve 3 is commanded on and pressure switch 3 remains off for 5–12 s, depending on the transmission fluid temperature.
