Two Position Selector Valve

Constant air pressure is supplied from the slave valve to the A-3546 range valve “S” port (1).

For LO range (range knob down (2), selector valve button in the “DIR” position (3), air flows out of the range valve “P” port (4).

For direct operation (range knob up (2), selector valve button in the “DIR” position (3), the knob prevents the air from passing through the selector valve: air now flows through the “H” port and into the selector valve (5).

For Underdrive and Overdrive operation (range knob up (2), selector valve button in the forward position (3) air flows through the selector valve “H” port (4) and out the “SP” port (5).

A-4900/A-6913 Roadranger Valve

Constant air pressure is supplied from the slave valve to the Roadranger valve “S” port (1).

For LO range (range lever down (2), splitter button rearward (3), air flows out of the Roadranger valve “P” port (4).

For HI range (range lever up (2), splitter button rearward( 3), the lever prevents the air from passing through the Roadranger valve: air now flows through the “H/L” port (4) into the Roadranger valve.

For splitter operation (range lever up (2), splitter button forward (3),air flows through the “H/L” port and air flows out of the Roadranger valve “SP” port (4). Air pressure which was in the outlet line is exhausted out the bottom of the Roadranger valve.

The roadranger valve mechanical interlock prevents forward movement of the splitter button while in LO range.

A-5013/A-6913 Roadranger Valve

Constant air pressure is supplied from the slave valve to the roadranger valve “S” port (1).

For LO range direct (range lever down (2), actuator button rearward (3),air flows out of the Roadranger valve “P” port (4).

For LO range overdrive (range lever down (2), actuator button forward (3) air flows out of the roadranger valve “P” port and “SP” port (4).

For HI range direct (range lever up (2), actuator button rearward (3),the lever prevents the air from passing through the Roadranger valve (4).

For HI range overdrive (range lever up (2), actuator button forward (3),air flows out of the Roadranger valve “SP” port (4). Air pressure which was in the outlet line is exhausted out the Roadranger valve bottom.
