OVERDRIVE 9 - 3 NOTE: Unless otherwise designated all instructions and operations are for overdrive transmissions used with either the single lever type or double lever type manual control transmissions. TRANSMISSION OVERDRIVE used, making available the acceleration so desirable at lower speeds. As the car speed increases above the cut-in point the overdrive unit will shift into overdrive ratio, but only when the driver desires no further acceleration; when consciously, or unconsciously, he lifts his foot from the accelerator, whereupon the shift is completed. Thereafter, the overdrive remains in effect until the car speed falls below the "cut-out" points, 16 to 19 mph, when the overdrive is released. However, at high speeds, the driver while operating in overdrive may require additional acceleration beyond that available by opening the throttle wide. His natural impulse is to press the accelerator further, and his act releases the overdrive, making available the full acceleration of direct drive. The direct drive is retained as long as the full acceleration is required; when the driver no longer requires it he lifts his foot from the accelerator, whereupon the overdrive is resumed. If the driver so desires, he may retain the direct drive indefinitely by maintaining a small amount of throttle opening. CITY TRAFFIC DRIVING: FIGURE 3 OPERATION Overdrive provides a driving ratio of engine speed to rear wheel speed that is numerically lower than direct drive. In overdrive the engine revolves 30% slower than in direct gear at the same car speed, resulting in less wear on engine parts as well as greater fuel and oil economy and smoother operation at high speeds. HIGHWAY DRIVING: When the car is operated below a predetermined "cutin" speed, varying from 18 to 21 mph, the direct drive is Much city driving is under conditions which permit speeds of 20-32 mph, with frequent stops. Many drivers are accustomed to start in second gear under such conditions. With overdrive-equipped cars, the driver may start in second gear, accelerate up to the "cut-in" speed, an, by merely lifting the foot from the accelerator pedal, engage the overdrive-second gear combination, which is approximately the same ratio as the usual third speed. At the first traffic stop, it is merely n e c e s s a r y to release the clutch; the gear shift lever is not touched. Furthermore, if a special burst of acceleration is needed in a tight traffic spot, the full power of second gear may be had by pressing the accelerator to the floor, resuming the overdrivesecond by the usual method of closing the throttle.
