e. R (Reverse) Position (See Fig. 8)
The rear clutch and the low-reverse band are
applied. All other friction elements are released.
The power flow is from the torque converter
turbine through the input shaft to the rear
clutch hub (part of the front clutch retainer).
The rear clutch is splined to the reverse sun
gear. The carrier of the reverse (front) plane-
tary gear set is held stationary by the low-
reverse band; therefore, the set acts as a sim-
ple reverse train through the reverse planet
pinions to the reverse annulus (which is splined
to the output shaft drive housing) and provides
a reverse ratio of 2.20 to 1.
1 N (Neutral) Position
All friction elements are released. Hence, there
is no drive connection between the engine and
the rear wheels.

The chart summarizes power flow conditions in
the various ranges as regards to gear train ele-

THE HYDRAULIC CONTROL SYSTEM
(REFER TO FIGS. 9 THROUGH 15)
The hydraulic control system must furnish
oil pressure and route it at the proper time and
pressure to the proper piston device for en-
gaging the transmission in the desired gear.
This system is composed of several parts whose
functions are interrelated.
