fort and fuel economy. With normal*
truck speed, a needed spurt of "pass-
ing" or "pick-up" speed can be ob-
tained by depressing the accelerator
completely (past detent). The drive
will then change to a lower speed
for a rapid pick-up, and will return
automatically to higher speed as

Operating in "1-3" Range (Automatically shifts from lst
thru 3rd)
The "1-3" Range (fig. 30) is used for better acceleration
when driving in congested traffic. This range may also be used
when ascending or descending long grades. At normal* truck
speed, a forced down shift to lower
speed can be obtained by completely
depressing accelerator pedal. Shift
again to higher speed will auto-
matically be made as truck speed
increases or accelerator is released.
Shift can be made from "1-4" to
"1-3" at any truck speed on dry
roads or from "1-3" to "1-4" at

'The speeds at which a forced downshift can be made in "1-4" and "1·3" ranges
vary according to tire sizes and axle ratios.
Operating in "1·2" Range
The "1-2" Range (fig. 31) is used for pulling through mud,
sand and snow, for going up grades or to provide braking on

also be used to place vehicle in
motion on icy roads. When in this
range the %, 1 and 1% Ton Models
start in 1st speed while the % Ton
Models start in 2nd speed under light
and medium throttle. At a truck
speed of less than 25 mph, the shift
from "1-4" or "1-3" range to the "1-2"
range may be made to obtain braking
by first releasing the accelerator,
then moving the lever to the "1-2"
position.
