panel to the left of the steering column. Range
selection is made by pushing the proper button.
Should the R (reverse) button be pushed in,
above approximately 15 M.P.H., it will move
the manual control lever to the neutral position
and when car speed drops below 15 M.P.H. it
will again be necessary to reposition the R (re-
verse) push button.
Mechanical connection between the gearshift
control housing and the transmission manual
control valve is obtained through the use of a
single push-pull cable, as shown in Figure 3.
One end of the wire cable is secured to the ca-
ble actuator in the gearshift control housing,
while the other end enters the adapter housing
on the transmission case to engage the manual
control valve lever assembly.
Operation
When a button is pushed in, the slide contacts
the cable actuator, causing it to pivot. Move-
ment of the cable actuator about its axis moves
the attached wire cable.
When the button nears its limit of travel, a
lock spring on the push button slide engages
the actuator shaft. This action allows the lock
spring to hold the button in the engaged posi-
tion. (Refer to Fig. 3).
When the operator pushes another button, to
select a different range, the top or bottom por-
tion (depending on which button was pushed)
of the slide contacts the actuator, thereby re-
leasing the first button from the restraint of
the lock spring. The first button is then free to
return (under spring force) to its original
position.
A back-up light switch (when so equipped)
is incorporated in the gearshift control housing
and is operated by the R (reverse) push button
slide.
A motor starting switch is also incorpo-
rated into the gearshift control housing. (Re-
fer to Fig. 3). The car is started by turning
the ignition switch to "ON" and pressing the
N (neutral) push button beyond the neutral
position to engage the motor starting switch.
Should the car stall, it is restarted by fully
depressing the N (neutral) push button.
