B)  Technician B 
C)  Both A and B 
D)  Neither A nor B

Question 8

In a hydraulically controlled transmission, how is vehicle speed measured?

B)  Vehicle Speed Sensor 
C)  Governor 
D)  None of the above

Question 9

When adjusting a vacuum modulator, adjustments should be made in small increments to prevent shifting problems.

Accepted Answer

A) True 
 B)False

Question 10

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

Accepted Answer

A)  2-3 shift valve 
B)  transmission pan 
C)  first gear clutch or band 
D)  none of the above

Question 11

Technician A says typically on hydraulic controlled transmissions, downshifting was often accomplished through the use of a kickdown valve. Technician B says in some transmissions, the kickdown valve was called a detent valve. Who is correct?

Accepted Answer

A)  Technician A 
B)  Technician B 
C)  Both A and B 
D)  Neither A nor B

Question 12

Line pressure in an automatic transmission needs to be regulated to help control the quality of the shift.

Accepted Answer

A) True 
 B)False

Question 13

When governor pressure exceeds 1-2 shift valve spring pressure, the port to the first gear clutch or band is shut, releasing it.

Accepted Answer

A) True 
 B)False

Question 14

Typically, a directly mounted governor to the output shaft has how many valves?

Accepted Answer

A)  One 
B)  Two 
C)  Either one or two 
D)  None of the above

Question 15

Technician A says transmissions can prevent a downshift that would exceed the engine's maximum rpm. Technician B says reverse only uses one speed so line pressure is directly applied by the manual valve to the appropriate apply devices. Who is correct?

Accepted Answer

A)  Technician A 
B)  Technician B 
C)  Both A and B 
D)  Neither A nor B

Question 16

Technician A says high-performance automatic transmission rebuild kits often contain a stiffer pressure-regulating spring to increase transmission pump pressure. Technician B says that on older mechanical pressure regulated transmissions, it was a common practice to remove the pressure regulator valve to increase the regulated pump pressure on high-performance transmissions. Who is correct?

Accepted Answer

A)  Technician A 
B)  Technician B 
C)  Both A and B 
D)  Neither A nor B

B)  low-reverse port. 
C)  transmission pan. 
D)  none of the above.

Question 18

As governor pressure increases, it pushes on the shift valves towards their upshift position. What determines the sequence in which the shift valves move?

Accepted Answer

A)  Line pressure 
B)  Spring tension 
C)  Throttle pressure 
D)  Governor pressure

Question 19

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?

Accepted Answer

A)  Technician A 
B)  Technician B 
C)  Both technicians 
D)  Neither technician

Question 20

Transmission line pressure is varied based on engine load and the selection of certain gears to maintain the ideal application force of the clutches and bands.

Accepted Answer

A) True 
 B)False
