The Eaton Fuller Range Section Assembly, part number S-1901 or S1901, is a genuine OEM range section unit for Fuller RTX-16709 and RTXF-16709 series transmissions. Parts manual references confirm fitment in four specific models: RTX-16709B, RTX-16709H, RTXF-16709B, and RTXF-16709H. The range section is the rear portion of a twin-countershaft transmission that provides the high/low range split, effectively doubling the number of forward gear combinations. Associated hardware listed in the RTX-16709B parts manual alongside this assembly includes magnetic plugs (part 20224), mechanical plugs (part 20226), an O-ring for use with the mechanical plug (part 14142), and lifting eyes (part 20815).
