OVERDRIVE 9 - 29
B. Occasionally, the upper contacts of the kickdown switch
will not open. To test for this condition disconnect "A"
generator wire at generator and connect loose end of
wire to negative post of battery. Ground overdrive wire
at control switch or governor; this should cause the
solenoid to click. Press the accelerator pedal all the way
to the floor; this should cause a second click; no click
indicates a defective kickdown switch, or that the kickdown
switch is not being opened. See Condition No. 3
"Throttle Switch Improperly Adjusted".
CONDITION NO. 10
ENGINE CUTS OUT WHEN kickdown IS AT-
TEMPTED:
With engine running, press kickdown switch stem with
hand. If engine stops, disconnect wire from No. 6 terminal
of solenoid and press switch stem again. If engine does not
stop, it indicates a damaged No. 6 terminal insulator in the
solenoid cover, or a defective solenoid. If the engine stops
with this terminal disconnected, it indicates either a
grounded wire between the kickdown switch and the solenoid,
or a defective kickdown switch.
CONDITION NO. 11
HARD SHIFT INTO REVERSE:
NOTE: A car equipped with Overdrive is normally more
difficult to shift into reverse than a car with a standard
transmission. When the car is new and all controls a little
stiff the shift into reverse will be easier if done as follows:
A. Shift lever into reverse position as far as it will go easily,
then allow clutch to engage slightly while continuing to
push on lever.
B. If unusual difficulty is experienced at any time, shift to
reverse can be made much easier by pulling Overdrive
control button "out" before shifting.
C. If shift to reverse is impossible, make check under
Condition 15, "Remains in Overdrive after car is
stopped".
CONDITION NO. 12
FREE WHEELS AT SPEEDS OVER 16-21 MPH.
A. If continuous, make checks for failure to shift into Overdrive,
Condition No. 7.
B. If intermittent, check for poor electrical contacts in all
parts of Overdrive wiring.
CONDITION NO. 13
SHIFTS OUT OF OVERDRIVE AT SPEEDS ABOVE 21
M.P.H.
See check for intermittent free wheeling under "Free
Wheels at Speeds Over 16-21 M.P.H."
CONDITION NO. 14
TRANSMISSION LOCKED:
NOTE: If transmission does not shift out of overdrive
when the car is brought to a stop and the car then rolls
backward slightly, the transmission will lock. The car
cannot be moved forward or backward by the engine or by
towing. Make check under Condition No. 8 "Fails to Shift
Out of Overdrive Below 16 to 21 M.P.H.", under Test A.
CONDITION NO. 15
REMAINS IN OVERDRIVE AFTER CAR IS STOPPED:
If car is in overdrive, engine running, a clicking noise will
be heard whenever the relay plug is connected or disconnected.
To remedy this condition, make checks as outlined under
Condition No. 8.
