Harsh-shifting transmission could be caused:
if the line pressure is too low during normal cruising speeds
when the line pressure is too high during normal cruising speeds.
when the line pressure is too low during low cruising speeds
when the line pressure is too high during high cruising speeds
Technician A says that the throttle valve is controlled by a cable or linkage hooked to the engine throttle linkage. Technician B says that a misadjusted throttle valve cable can prevent wide-open throttle (WOT) on an engine. Who is correct?
Tech A
Tech B
Both Tech A and B
Neither Tech A or B
When checking the effect of throttle pressure on line pressure, which of the following might you read on a properly operating transmission with the throttle valve closed?
15 PSI
50 PSI
75 PSI
200 PSI
If the vacuum modulator's diaphragm becomes ripped, the customer may report that the vehicle shift is extremely delayed and harsh, often shifting only at the engine red line, regardless of the driving condition or throttle position.
True
False
After leaving the automatic transmission's cooler, the transmission fluid is ready to enter the transmission lubrication circuit. Which parts are typically lubricated by this circuit?
Clutches and front pump assembly
Bushings and planetary gears
Transmission pan and filters
The torque converter and flexplate
Technician A says to check the effect of throttle pressure on the boost valve, you do not need to disconnect the throttle cable or linkage. Technician B says to check the effect of throttle pressure on the boost valve, you need to connect a pressure gauge to the transmission line pressure test port.
Tech A
Tech B
Both Tech A and B
Neither Tech A or B
Engine vacuum, atmospheric pressure and spring tension all work on the vacuum modulator diaphragm. Which of the following statements describes the action of these forces on the diaphragm?
As manifold vacuum increases, it works with atmospheric pressure to stretch the spring, increasing modulator pressure
As manifold vacuum decreases, the spring extends, increasing modulator pressure
As atmospheric pressure changes, there is an inversely proportional change in modulator pressure
As manifold pressure changes there is a directly proportional change in modulator
Technician A says that when governor pressure on one side of a shift valve overcomes spring pressure and throttle pressure on the other side, an upshift occurs. Technician B says when reverse boost pressure on one side of the reverse valve overcomes governor pressure on the other side, shift into reverse occurs. Who is correct?
Tech A
Tech B
Both Tech A and B
Neither Tech A or B
Which of these is least likely to cause harsh shifting during normal cruising speeds?
High line pressure
Low line pressure
Broken or missing accumulator spring
None of the above
When does the kickdown valve force downshifts?
Wide open throttle
Three-quarters open throttle
Half open throttle
One-quarter open throttle
Technician A states that the pump sends fluid out under pressure. This release of fluid creates line pressure. Technician B states that line pressure sent to the throttle valve is mostly exhausted to the transmission pan when the throttle is open and the vehicle is under load. Who is correct?
Tech A
Tech B
Both Tech A and B
Neither Tech A or B
When the governor pressure becomes great enough to overcome the spring pressure and the modulator/throttle valve pressure in the 2-3 shift valve, line pressure is allowed to flow to:
the 3rd gear clutch or band
the 2nd gear clutch or band
the 1st gear clutch or band
the reverse gear clutch or band
The pressure regulator valve keeps the pressure at a regulated level by exhausting excess pressure back to the ________.
Pump
Pipe
Transmission pan
Valve
The automatic transmission's pressure regulator valve keeps the pressure at a regulated level by exhausting excess pressure back to the transmission pan.
True
False
If a vehicle is coasting in third gear, governor pressure ________ as the vehicle speed drops, causing the 2-3 shift valve to move back to the downshift position.
Equalizes
Spikes
Reduces
Increases
If vehicle speed decreases, governor pressure is reduced, resulting in the shift valve moving back to the downshift position.
True
False
Automatic transmission line pressure that is sent to the governor is allowed to be exhausted back to the transmission pan when the vehicle is not moving and the governor is not creating any pressure.
True
False
When the driver _______ the vehicle, the front pump draws fluid up from the transmission pan, through the filter, and into the pump.
Starts
Stops
Speeds up
Slows Down
Technician A says when the vehicle is in the park position, line pressure is able to flow past the manual valve to any components in the transmission. Technician B says when the vehicle is in the park position, line pressure is not able to flow past the manual valve to any components in the transmission. Which technician is correct?
Tech A
Tech B
Both Tech A and B
Neither Tech A or B
Which of the following pressures is not used in reverse, because there is only one speed available?
Governor pressure
Modulator pressure
Throttle valve pressure
All of the above
