Chapter 5 Quiz

In a manual transmission, the ​ (a)   controls what gear the transmission is in.

• accelerator

• shift lever
• brake pedal

• clutch

When your vehicle reaches the maximum speed for a gear, you must:

• upshift.

• downshift.

• pump the brakes.

• push the accelerator.

When double clutching is done correctly, and the RPMs are matched during the shift,

• it gives you time to determine what gear comes next.

• it enables you to get in a rhythm with the engine.

• it helps you wait for the 500 RPM change before changing gears.

• the gears do not grind.

Downshifting early is a common error that may:

• make it impossible to get into the next lower gear.

• cause the clutch to burn out.

• allow the engine to rev at a low level, possibly causing the vehicle to stall.

• make the clutch to pop out forcefully.

The purpose of upshifting is to:

• match road speed with engine power.

• allow the vehicle to increase speed.

• slow down the vehicle.

• transfer power from the transmission to the engine.

Proper, smooth shifting is important because if you shift before your vehicle is ready:

• your entire tractor-trailer may jerk forward.

• your drive wheels may lock up momentarily.

• you could lose control of your vehicle.

• all of the above.

What actions negatively impact your vehicle’s fuel economy?

• Sitting in too low of a gear (causes the motor to bog down)

• Using double clutching (causes the RPMs to drop too low)

• Downshift too early (causes the RPMs to jump up)

• Using heel-toe acceleration technique (causes the gears to slip)

With an autoshift transmission, if the transmission is in the drive position:

• you will use a button control to shift through all gears.

• it will shift gears as needed based on speed and load.

• only the top gears will automatically change.

• none of the above.

What is the primary difference between a manual and semiautomatic transmission?

• The top gears automatically change in a manual transmission

• A semiautomatic transmission does not use a clutch and gearshift lever

• The top gears automatically change in a semiautomatic transmission

• A manual transmission uses electronic controls to help you shift

What does an automatic transmission use to change gears?

• Torque converter

• Range control lever

• Lever or button

• Both A and C
