The main components of the drivetrain are the transmission, differential, and drive axles.
correct answers True
An engine develops torque that can be multiplied by transmission gears. correct answers True
Large amounts of engine vacuum are formed in the cylinders during the exhaust stroke.
correct answers False
The driveline can multiply both power and torque. correct answers False
As torque is multiplied, rotation speed is also multiplied. correct answers False
Overdrive gears have ratios of less than 1:1. correct answers True
Most automatic transmissions use at least one planetary gear set. correct answers True
Hydraulically activated brake bands and multiple-friction disc packs are used to direct power
flow through the transmission. correct answers True
Some hybrid electric vehicles (HEVs) use a CVT that is based on the use of electric
motors/generators to vary drive ratios. correct answers True
Most modern automatic transmissions rely on mechanical, hydraulic, and electronic
components to accomplish gear ratio changes. correct answers True
Most torque converters consist of an impeller, a turbine, and a stator. correct answers True
The weight of a standard transmission flywheel is equal to the weight of an automatic
transmission flexplate. correct answers False
RWD vehicles use a long steel tube, using two universal joints and a slip joint, to connect the
transmission to the rear axle. correct answers True
The main purpose of a differential gear set is to allow equal wheel speed when a vehicle is
turning a corner. correct answers False
A transfer case is used in a 4WD vehicle to allow torque to be transferred to the front-drive
axles. correct answers True
The most common use for hypoid gears is in modern differentials. correct answers True
A bushing is the simplest type of bearing. correct answers True
Many bearings must be capable of withstanding both radial and axial loads. correct answers
True
Automatic transmission fluid (ATF) is responsible for the operation, lubrication, and cooling
of the internal parts of the transmission. correct answers True
, All ATF have the same characteristics; therefore, it does not matter which ATF you add to a
particular vehicle. correct answers False
Transmission fluid filters, although different in appearance and composition, have the same
function. correct answers True
The sun gear has teeth on the outer surface. correct answers True
Which of the following is a component of the drivetrain. correct answers Transmission
Differential
Drive axle
(All of the above)
Engine vacuum is largely determined by which of the following? correct answers Engine load
Which device is used to transfer engine torque to an automatic transmission? correct answers
Torque converter
Technician A says that gears may be used to apply torque to other rotating parts. Technician
B says that gears may be used to multiply torque. Who is right? correct answers Both
In order to create a low-pressure area in the cylinder during the intake stroke, the volume of
the cylinder does which of the following? correct answers Increases
Technician A says a torque converter transfers engine power to the transmission, by hydraulic
force.

Who is correct? correct answers A only
Technician A says by multiplying the number of teeth on one gear by the number of teeth on
a second gear, a gear ratio can be determined.
Technician B says the mathematical relationship, according to the number of teeth, of one
gear to another is expressed as a gear ratio.
