After shifting out of the first gear position, use the
Roadranger® "repeat H" shift pattern. Select both LO
range and HI range with the range lever (range
knob). It is used once during the upshift sequence
and once during the downshift sequence.
Always preselect the range shift. After preselection,
the transmission will automatically make the
synchronizer range shift as the shift lever passes
through neutral.
Eaton Fuller 10-Speed Models
Eaton Fuller 10-speed range-shift models are not
synchronized. They have ten forward speeds and
two reverse speeds. The shift lever controls five
forward gears and one reverse gear in the
transmission front section, and the range lever
controls a LO and HI range in the two-speed
auxiliary section. The five forward gears selected in
LO range are used again in HI range to provide the
10 progressive forward gears. See
Fig. 15.5 for the
shift patterns. See
Table 15.1 for the shift
progressions.
Once the highest shift lever position (fifth gear) is
reached in LO range, the driver preselects the range
shift lever for HI range. The range shift occurs
automatically as the shift lever is moved from fifth
gear position to the sixth gear position.

Table 15.1, Eaton Fuller Shift Progressions
When downshifting, the driver preselects the range
lever for LO range and the range shift occurs
automatically during the shift lever movement to the
next gear position.
Eaton Fuller Deep-Reduction Models
Eaton Fuller deep-reduction models are not
synchronized. They have a five-speed front section
and a two-speed auxiliary section which has an extra
deep reduction gear. The LO gear in the front section
is used only as a starting gear. The other four ratios
are used once in LOW RANGE and once in HIGH
RANGE giving eight highway ratios. LO-LO is
selected by the DEEP REDUCTION lever on the
dashboard. See
Fig. 15.6 for the shift pattern.
