CHRYSLER SERVICE MANUAL
TOROUE-FLITE TRANSMISSION—11
1/2 half mile or more. Lower ratios reduces the
possibility of overheating the transmission un-
der these conditions. (1) low position is for
service operation or to obtain better control.
e. Transmission Inoperative
Tow the vehicle with a rear end pickup or re-
move the propeller shaft.
f. Transmission Operating Properly
The vehicle may be towed safely in N (neutral)
at moderate speeds. For long distance towing
(over 100 miles), the propeller shaft should be
removed.

POWER FLOW IN THE TRANSMISSION
a. (Drive) Position Breakaway (See Fig. 4)
The power flow is from the converter turbine
through the input shaft and front clutch re-
tainer (one unit). The front clutch is applied
and the drive continues through the clutch hub
to the intermediate shaft and kickdown annu-
lus gear (one unit). The kickdown annulus gear
drives the kickdown planet pinion gears, ro-
tating them in the same direction. The kick-
down planet gears are meshed with the kick-
down sun gear which in turn is integral with
the reverse sun gear. Both sun gears are forced
to rotate in a reverse direction by the reaction
of the kickdown planet pinion carrier together
with the reverse annulus gear, both of which
are splined to the output shaft drive housing.
The reverse planet pinion carrier is attached
to and prevented from turning backward by
an overrunning clutch and becomes stationary
in forward drive (overruns on coast). There-
fore,
the reverse planet carrier pinions are
forced to rotate in a forward direction and
force the reverse annulus to rotate in the same
direction transmitting the power flow to the
output shaft with the resulting ratio of the
kickdown and reverse planetary gear sets of
2.45 to 1.
b.
(Drive) Position-—2nd Speed and 2 (Second)
Position—2nd Speed (See Fig. 5)
The power flow is from the torque converter
turbine through the input shaft to the front
clutch (which is applied).
From the front clutch through the interme-
diate shaft to the annulus gear of the kickdown
(rear) planetary gear set. The kickdown band
is applied which holds the sun gear stationary.
The annulus gear drives the kickdown planet
pinions which rotate in the same direction as
the input and intermediate shafts. The kick-
down planet pinions are meshed with the sun
gear; therefore, they walk around this gear and
exert force through the kickdown planet pinion
shafts to rotate the kickdown planet pinion car-
rier. The carrier, which is splined to the output
shaft drive housing, rotates at a slower speed
than the annulus gear, thus providing a gear
ratio of 1.45 to 1.
