What Does “I” Letter mean on Gear Shift?
Before providing an answer to this question, it would be nice to clear some misconceptions. Certain myths surround the discussion of manual and automatic transmissions; let’s take a quick look at some of them.
- Cost: Many people think that an automatic transmission vehicle is more pricey than a manual one.
Of course, this notion is not entirely true. A few vehicle models from the popular General motors brand have cars that go for a higher price. If you are a car enthusiast, you should know that the price of a car is determined by a lot more than its transmission system.
- Off-road driving: A few people believe that automatic transmissions cannot navigate through off-road terrains as much as the manual. This myth is false. The choice of any of the transmission systems depends on your preference and the application of the right gear. However, when it comes down to off-road racing and shifting gears in a swift manner, automatic transmission cars are better off.
How does an automatic transmission operate?
Before now, a Hydraulic control system controlled the changing of gears in an automatic transmission. This system served as a pathway to regulate the constant flow of transmission fluid under pressure. You may ask why? The constant fluid under pressure by an oil pump serves three purposes; Lubrication, cooling and shift control. However, with newer automatic transmission models, both hydraulic and electronic controls are incorporated. When the engine is not in use, the transmission lacks the oil pressure to operate and poses difficulty to push-starting the vehicle.
In a manual transmission system, the driver changes gear by pushing on the clutch pedal, whereas; a torque converter handles that of an automatic mathematically. The latter decreases and increases gear effortlessly and transmit torque through a network of bands and clutches know as the Planetary gear train.
