A+
What device is used to transfer engine torque to an automatic transmission?
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?
Both A and B
Technician A says a torque converter transfers engine power to the transmission,
operating by a hydraulic force. Technician B says a torque converter divides torque
evenly. Who is right?
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 in a gear ratio. Who is correct?
B Only
By applying the engine's torque to one of the gears in a planetary gear set and
preventing another member from moving, which of the following changes can take
place?
a) torque multiplication
b) speed increase
c) change in direction
d) all of the above
d) all of the above
Technician A says that in a RWD vehicle, the transmission and drive axle are located in
a single assembly. Technician B says a transaxle is a single assembly containing the
transmission and drive axle. Who is correct?
B Only
Technician A says the manual shift valve, which is located in the valve body, moves
indirectly to the movement of the throttle pedal. Technician B says the manual shift
valve in the transmission is moved by the gear selector lever and linkage. Who is
correct?
B only
Technician A says delayed shifts using a TV assembly may be the result of poor engine
performance. Technician B says low engine vacuum will cause a vacuum modulator to
sense a load condition, causing delayed and harsh shifts. Who is correct?
Both A and B
An automatic transmission or transaxle receives engine power through what part?
A torque converter
Technician A says leaking hydraulic circuits or sticking spool valves in the valve body
can result in delayed shifts or slippage. Technician B says worn planetary gear set
members can cause delayed shifting. Who is correct?
A only
, Which of the following is true of an impeller
a) it allows for torque multiplication
b) it is splinted to the input shaft
c) it is driven by the converter cover
d) it supplies pressures to be used within the valve body
C) it is driven by the converter cover
Technician A says the valve body senses and responds to engine and vehicle load.
Technician B says valve bodies house many different valves that are moved by the gear
selector. Who is correct?
A only
Technician A says the torque converter's stator indirectly drives the oil pump.
Technician B says any engine movement can change the effective length of the shift
and throttle cables and can affect the engagement of gears. Who is correct?
B only
Technician A says hydraulic problems, not linkage problems, cause delayed or missed
shifts. Technician B says any engine movement can change the effective length of the
shift and throttle cables can affect the engagement of gears. Who is correct?
B only
Technician A says throttle pedal movement or engine vacuum is an indicator of engine
load. Technician B says changes in hydraulic pressure inside the transmission or
transaxle are a result of engine load changes. Who is correct?
Both A and B
Which of the following does not sense engine vacuum?
a) manifold absolute pressor sensor
b) throttle position sensor
c) pressure regulator valve
d) modulator valve
e) B or C
E) B or C
Technician A says electrical switches are used to open and close electrical circuits.
Technician B says electrical switches are used to control the operation of other devices.
Who is correct?
Both A and B
Technician A says a one-way clutch in the stator allows it to remain stationary when it is
not needed. Technician B says the flow of fluid from the impeller to the turbine is
directed with the aid of the stator. Who is correct?
Neither A nor B
Technician A says the impeller is driven by the force of the fluid from the turbine and is
splinted to the input shaft. Technician B says the torque converter's impeller is driven by
the converter cover, and its rear hub drives the transmission's or transaxle's oil pump.
Who is correct?
B only
Technician A says identification numbers identify only the manufacturer and assembly
date of the transmission of transaxle. Technician B says the shape of the oil pan is the
only positive way to identify the exact design of the transmission or transaxle. Who is
correct?
