TORQUEFLITE TRANSMISSION
1.
DESCRIPTION OF TRANSMISSION
The transmission (Fig. 1) combines a torque
converter and an automatic three-speed plane-
tary gear box. The torque converter extends
torque mutiplication over a wide range of en-
gine speeds. The transmission consists of two
multiple disc clutches, an overrunning clutch,
two bands, and two planetary gear sets to pro-
vide three forward ratios and a reverse ratio.
With the front or forward clutch engaged and
low gear reaction, transferred through the
transmission overrunning clutch assembly, a
low ratio of 2.45 to 1 is obtained. Engagement
of the kickdown or second speed band will shift
the transmission to second speed ratio (1.45 to
1).
Disengagement of the kickdown band and
engagement of the rear or direct clutch locks
the gear set so that a direct drive ratio of 1 to
1 is obtained. Since the overrunning clutch can
transmit torque only on the drive side, it is
necessary to apply the low and reverse band
when using low for engine braking. Reverse
ratio (2.20 to 1) is obtained by application of
the rear clutch and rear band. In the drive
range, the transmission shifts through all three
gear ratios automatically. Shift points are de-
termined by throttle opening and car speed. If
additional acceleration is desired while in drive
range, the transmission will downshift (de-
pending on vehicle speed) to second gear or
breakaway automatically when the accelerator
pedal is completely depressed.
The intermediate or second position range is
used to operate the transmission in the first two
gears only. This range is suitable for heavy
city traffic where the driver may desire part
throttle second gear operation for more precise
speed control. It may also be used on long
down grades where additional engine braking
is needed. A low or first position range is also
available to keep the transmission in first gear
only. This position provides added handling
ease in mountain driving and exceptional pull-
ing qualities in sand and snow.

GEARSHIFT CONTROL UNIT
The transmission is operated by a gearshift
control unit consisting of five push buttons,
identified by R (reverse), N (neutral), D
(drive), 2 (second) and 1 (low). Refer to
Figure 2.
The control unit is located on the instrument
