desired.
The driver should, therfore, first familiarise himself with the approximate speeds at which the automatic
changes occur. These are as follows :
D Range
Up-changes (m.p.h.)
1-2
2-top
Light Throttle
11
15
Full Throttle
40
76
The owner-driver who wishes occasionally to indulge in a very fast get-away will obtain maximum
acceleration by allowing the automatic gearbox to make full throttle changes throughout the speed
range.
The automatic down-change at light throttle will normally occur at the following speed :
Top to 1st direct
8 m.p.h.
Under “Kick-down” conditions down changes occur at speeds below the following limits :
Top to 1st
37 m.p.h.
Top to 2nd
68 m.p.h.
Caution must be observed when making a “Kick-down” change at speeds below 32 m.p.h. in view
of the sudden surge of power engendered.
MANOEUVRING
When manoeuvring, “D” should be selected for forward movement. Reverse gear can be selected
whilst vehicle is in forward motion but only below 17 m.p.h.
MOUNTAIN DRIVING
When driving in mountainous country or with heavy loads, the 2 or 1 position should be selected on
upgrades which require heavy throttle for half a mile or more. Lower ratios reduce the possibility of
overheating the transmission and converter under these con-ditions. The 1 position is for severe
operation or to obtain better control or for operation in descending a steep hill.
IDLING
Neutral (“N”) should be selected when it is necessary to idle the engine for an extended period.
COASTING
Coasting must be avoided at all times, otherwise the gearbox may suffer serious damage due to lack
of lubrication.
TOWING
Transmission Inoperative.
The vehicle should be towed with a rear end pick-up or remove the propeller
shaft.
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.
PUSH STARTING
If the engine fails to start in the normal manner, it may be started by pushing the car. Towing is not
recommended due to the sudden surge of power when the engine starts. Turn the ignition on, then
engage 1 (low) position and depress the accelerator pedal slightly; after the vehicle has been pushed
to a speed of 15 to 25 m.p.h. (approximately), the transmission will drive the engine.
