1 lesson 3.4 DRIVING WITH A MANUAL TRANSMISSION It will be easier to learn good manual transmission skills after you have learned how to use the steering wheel, brake pedal, and accelerator, and have developed skills to manage space.The copyright holder has not granted permission to display this photograph in a downloadable format.

3 Drive Right chapter 3Monday, April 17, 2017Manual TransmissionThe purpose of a transmission is to convert engine speed into power to turn the wheels of a vehicle.As speed is increased, there is less need for power. Shifting gears in the transmission changes how the speed of the engine is transferred to the vehicle’s wheels. While the lower gears of the transmission provide the greatest power, the higher gears allow for the highest speeds.Version 2
4 The purpose of the clutch is to connect the rotating engine shaft to the gears in the transmission. This connection is made with clutch plates held together by friction.When the clutch pedal is pressed down, the engine separates from the transmission, which allows the driver to change gears.
5 Compare the advantages and disadvantages of manual transmissions. OBJECTIVE
6 Advantages of Manual Transmission A manual transmission has better fuel economy.Cars with manual transmissions are less expensive and require less maintenance than cars with automatic transmissions.The driver has more control over how power is applied.
7 Disadvantages of Manual Transmission A manual transmission forces the driver to have one hand off of the steering wheel on a continual basis, which could result in less control during a critical steering situation.Inexperienced drivers may focus on shifting the gears instead of the traffic.A driver may inadvertently shift to the wrong gear, causing damage to the engine and transmission.There is a greater workload on the driver during heavy stop- and-go traffic.
8 To learn how to drive a car with a manual transmission, you can find detailed lessons on the Internet.You can also ask a licensed driver to help you.
9 Typical patterns of gear positions for manual transmissions. Positions may vary, especially for reverse (R).
10 Semi-Automatic Transmission Many auto manufacturers are producing semi-automatic transmissions, also known as a “clutchless manual transmission.”The clutch is replaced with electronics that allow the driver to shift gears manually by merely moving the shift lever.
11 lesson 3.4 review Explain the function of a clutch. List three advantages and three disadvantages to operating a vehicle with a manual transmission.
