How the S2543 Roadranger Valve Works

Low Range Operation (Range Lever Down)

Constant air pressure is supplied from the slave valve to the Roadranger valve inlet or "S" port (1). In LO range (range lever down), air passes through the lever and out the Roadranger valve outlet or "P" port (3).

High Range Operation (Range Lever Up)

In HI range (range lever up) the lever prevents the air from passing through the Roadranger valve. Air pressure which was in the outlet line (3) is exhausted out the Roadranger valve "E" port.

10-Speed Roadranger Shift Pattern

10th gear position: Over and down (towards the passenger seat) from 8th gear.
