Question 1

When the transmission is in park, line pressure sent to the throttle valve is sent to the __________ when the throttle is closed and the vehicle is under no load.
A) 1-2 shift valve
B) 2-3 shift valve
C) transmission pan
D) throttle valve

Accepted Answer

When the transmission is in park and the throttle is closed with no load, the line pressure is typically directed to the transmission pan as there is no need for it to engage any shift valves.

Question 2

When the transmission is shifted into drive, fluid moves through the 1-2 shift valve and into the:
A) 2-3 shift valve
B) transmission pan
C) first gear clutch or band
D) none of the above

Accepted Answer

When the transmission is shifted into drive, fluid moves through the 1-2 shift valve and into the first gear clutch or band to engage first gear.

Question 3

Technician A says that the higher the engine load or the more the throttle is opened, the higher the line pressure. Technician B says that as vehicle speed increases, so does governor pressure. Who is correct?
A) Technician A
B) Technician B
C) Both technicians
D) Neither technician

Accepted Answer

Both technicians are correct. Higher engine load or throttle opening increases line pressure, and vehicle speed increase raises governor pressure.

Question 4

When the second gear clutch has pressure going to it, the 2-3 shift valve has what pressure acting on it?
A) Governor pressure
B) 2-3 shift valve spring pressure
C) Both A and B
D) Neither A nor B

Accepted Answer

The 2-3 shift valve is influenced by both governor pressure and the spring pressure of the valve itself.

Question 5

Technician A says that a vehicle can downshift by fully depressing the throttle, allowing full throttle pressure to overcome governor pressure. Technician B says that a vehicle may downshift when governor pressure drops below line pressure. Who is correct?
A) Technician A
B) Technician B
C) Both technicians
D) Neither technician

Accepted Answer

Both technicians are correct. A vehicle can downshift by fully depressing the throttle, which increases throttle pressure to overcome governor pressure. Additionally, a vehicle may downshift when governor pressure drops below line pressure, as this indicates a need for a lower gear.

Question 6

Technician A says that a malfunctioning governor can cause a shifting problem between first and second gear. Technician B says that a broken shift valve spring can cause a shifting problem. Who is correct?
A) Technician A
B) Technician B
C) Both technicians
D) Neither technician

Accepted Answer

Both technicians are correct. A malfunctioning governor can affect the hydraulic pressure needed for shifting, causing issues between first and second gear. Similarly, a broken shift valve spring can prevent proper valve operation, leading to shifting problems.

Question 7

Technician A says that when a transmission is in second gear, governor pressure increases causing fluid to stop flowing to the second gear clutch and into the third gear clutch. Technician B says that when a transmission is in third gear, and governor pressure decreases, the transmission will downshift into second gear. Who is correct?
A) Technician A
B) Technician B
C) Both technicians
D) Neither technician

Accepted Answer

The answer of Technician A says that when a transmission...

Question 8

Technician A says that a transmission can only downshift from third into second in one shift. Technician B says that a transmission can shift from third into first in one shift. Who is correct?
A) Technician A
B) Technician B
C) Both technicians
D) Neither technician

Accepted Answer

Technician B is correct because a transmission can shift from third gear directly to first gear in one shift, depending on the design and operation of the transmission system.

Question 9

When in reverse, governor pressure and throttle/modulator pressure are sent to the:
A) 2-3 shift valve.
B) low-reverse port.
C) transmission pan.
D) none of the above.

Accepted Answer

The answer of When in reverse, governor pressure and throttle/modulator...

Quiz 10: Hydraulically Controlled Transmission

When the transmission is in park, line pressure sent to the throttle valve is sent to the __________ when the throttle is closed and the vehicle is under no load.

When the transmission is shifted into drive, fluid moves through the 1-2 shift valve and into the:

Technician A says that the higher the engine load or the more the throttle is opened, the higher the line pressure. Technician B says that as vehicle speed increases, so does governor pressure. Who is correct?

When the second gear clutch has pressure going to it, the 2-3 shift valve has what pressure acting on it?

Technician A says that a vehicle can downshift by fully depressing the throttle, allowing full throttle pressure to overcome governor pressure. Technician B says that a vehicle may downshift when governor pressure drops below line pressure. Who is correct?

Technician A says that a malfunctioning governor can cause a shifting problem between first and second gear. Technician B says that a broken shift valve spring can cause a shifting problem. Who is correct?

Technician A says that a transmission can only downshift from third into second in one shift. Technician B says that a transmission can shift from third into first in one shift. Who is correct?

When in reverse, governor pressure and throttle/modulator pressure are sent to the:
