automatic transmission section 2, 3 test questions and
answers 2023 with complete solution
Electronic controls make modern vehicles more fuel efficient and help lower
exhaust emissions.
T/F
true
Limp-in or fail safe mode sends power to a predetermined combination of
solenoids that give a driver a single gear, allowing vehicle operation to return for
service.
T/F
false
A TCM is a separate computer designated for automatic transmission/ transaxle
operation.
T/F
true
An EPC solenoid used in a computer controlled transmission replaces the
vacuum modulator system.
T/F
true
Disconnecting the battery ground cable should be the first step when removing a
transmission or transaxle.
T/F
true
what is pulse width
the amount of on time
A lock-up torque converter incorporates a parking pawl and linkage and is used
to lock the vehicle in Park.
T/F
false
A stator is used in a simple fluid coupling to redirect the fluid.
T/F
false
The two types of fluid flow inside a torque converter are vortex and reverse.
T/F
false
Technician A says the signals from the engine temperature sensor affect the
application of the converter clutch.
Technician B says at excessive fluid temperature the TCM will unlock the
converter clutch.
Who is correct?
both
While discussing amperage testing.
Technician A says power to the circuit is disconnected while testing.
Technician B says the ammeter is connected in series with the circuit if not using
, an inductive clamp.
Who is correct?
tech B
Technician A says in order to set a DTC the vehicle may have to be driven twice
(tested through two drive cycles).
Technician B says hydraulic or mechanical problems could be the cause of DTCs.
Who is correct?
both
Technician A says a solenoid that typically has a resistance less than 20 ohms is
an on/off solenoid.
Technician B says that a solenoid that typically has a resistance between 20-40
ohms is a variable force solenoid.
Who is correct?
neither
Technician A says sealing rings that are made of cast iron are considered "hard
parts".
Technician B says as part of the cleaning process to rinse the friction plates with
water thoroughly and dry with air.
Who is correct?
neither
Technician A says that electrical components that are to be reused should be
gently cleaned externally in solvent.
Technician B says to clean parts most shops use a sandblaster.
Who is correct?
tech A
Technician A says a vehicle that has poor acceleration may be the result of a
stator one-way clutch that fails to hold.
Technician B says a vehicle having acceptable low speed operation but poor high
speed performance may be the result of a seized stator one-way clutch.
Who is correct?
both
When discussing lip seals installation on a piston from a multiple disc clutch
pack.
Technician A says that the lip of the seal should face the pressure.
Technician B says to remove the seal when cleaning the piston.
Who is correct?
both
Technician A says when the coupling phase of the torque converter occurs and
no torque multiplication takes place, there is little vortex flow and the engine's
torque is carried through the converter by rotary flow of fluid.
Technician B says the impeller is the splined component within the torque
converter and is connected to the transmission input shaft.
Who is correct?
tech A
Technician A says excessive pressure in the torque converter will cause a torque
converter to balloon.
