174.6913

TRANSMISSION SELECTOR VALVE

The Automann 174.6913 is a transmission selector valve designed for Eaton Fuller 13‑speed RT/RTLO series manual transmissions. It is the air‑control unit the driver operates via the red splitter slider knob and black hi/lo flipper knob to shift between ranges and split gears. The valve directs air pressure to the transmission’s shift forks, enabling all 13 forward speeds. It is commonly replaced when the original valve develops air leaks, sticks, or causes hard shifting.
