Exam 8: Transmissions and Driveline Systems

The differential keeps the drive wheels rotating at the same speed when the vehicle changes direction.

Why is a flywheel weighted?

Gear ratios are computed by dividing the drive gear by the driven gear.

What is the name of the transmission design which uses two hydraulic clutches, two bands, two planetary gearsets, an overrunning clutch, and a valve body?

Constant velocity automatic transaxles utilize multiple gears to achieve fuel economy.

The word transmission refers to transmissions and transaxles.

Two technicians are discussing clutch linkages. Technician A says that many modern trucks use a mechanical linkage. Technician B says that many passenger vehicles utilize a hydraulic clutch linkage. Who is correct?

A typical drive shaft has two U-joints, a slip joint and a driveshaft tube.

The transmission housing is made of cast iron or aluminum.

What are four major internal components of a modern torque converter?

Two technicians are discussing clutch packs. Technician A says that a clutch pack and drum are serviced as a unit. Technician B says that clutch packs consist of a piston assembly, a drum, and steel and friction clutch plates. Who is correct?

Which gear is the reverse drive gear in a cluster gear?

The torque converters replaces the clutch assembly in a vehicle with an automatic transmission.

What part of the clutch mechanism is considered to be part of the engine assembly?

A transmission uses a driveshaft.

Two technicians are discussing electronic control of transmissions. Technician A says that control is based on hydraulic and vacuum controls. Technician B says that the transmission contains several computer sensors and actuators. Who is correct?

What component replaces the clutch assembly in an automatic transmission?

What is a compound gearset?

Briefly describe how a CVT changes torque and speed output.

Which component is excluded from the clutch assembly?
