Correct answer: Oxidation from overfilling
Oxidation from under or overfilling will cause the fluid to be varnished with a light to dark brown color.
Correct answer: X only
Misadjusted shift linkage is the cause of an automatic transmission that does not hold in PARK.
Correct answer: X only
Technician X is correct. The cause of an automatic transaxle loses pressure as it shifts from first to second gear is by the clutch piston seal.
Correct answer: Forward clutch
The other three repairs can all be done on-vehicle. If you experience shock when shifting through the N to D range, repairing a forward clutch requires off-vehicle repair. To access the forward clutch, you need to remove the front pump first.
Correct answer: Stays with transmission
This is the proper procedure when the transmission is not going to be disassembled. If left on the engine, all of the oil will leak out and make a huge mess.
Correct answer: Low line pressure
The reason why the transmission slips when cold because of the low line pressure.
Correct answer: Both X and Y
Both technicians are correct. Some reasons why transmission suffers from hard shifting: problem with the accumulator and sticking restricting orifice/check ball.
Correct answer: Technician X
Technician X is right. The oil pump assembly might be the diagnostic item and this requires an OFF-vehicle procedure.
Correct answer: Dirty transmission filter
A dirty filter will cause lower line pressure and the other choices listed will not.
Correct answer: throttle position sensor
Failed in throttle position sensor can make the automatic transaxle upshifts harshly during normal acceleration.
Correct answer: the intake air temperature sensor
The intake air temperature sensor is included to prevent the torque converter clutch from applying.
Correct answer: Technician Y
It’s up to you to pick the symptom from the online service information that matches as close as possible to the concern. Because most customers aren’t familiar with the online service information, they aren’t going to describe the symptoms the same way they are listed.
Correct answer: Flex plate check
Checking the flex plate is not part of the preliminary diagnosis process.
Correct answer: perform an air pressure test
The best way to pin-point an oil pressure leak is to perform an air pressure test.
Correct answer: normal bushing clearance is 0.015 to 0.025 inch (0.381 to 0.635 mm).
Normal bushing clearance is 0.015 to 0.025 inch (0.381 to 0.635 mm) is not related about bushing inspection and measurement.
Correct answer: Both X and Y
Both technicians are accurate. Tech X knows that noises and concerns with the driveline and suspension can often appear to come from the transmission or transaxle. To determine if it’s a transmission issue, put it in neutral and see if it changes or disappears. If it goes away, the transmission needs diagnostics. Tech Y is also correct because you should always start with simple inspections to make sure there’s nothing you’ve overlooked and can use a scan tool to get more information.
Correct answer: X only
Technician X is correct because low line pressure can cause the transmission to slip and operate sluggishly. Technician Y is wrong because the line pressure should not vary with engine speed. It must remain at a constant level to correctly operate the friction components. It will be lower at idle because of lower RPM as sensed by the TCM or PCM.
Correct answer: Clutch
Too much automatic transmission shaft end play cannot be caused by the clutch.
Correct answer: Both X and Y
Both technicians are correct. The Throttle Valve (TV) cable may need adjusting and the vacuum modulator may be damaged.
Correct answer: Neither Technician
Tech X is wrong because a damaged stator one-way clutch would lead to low engine stall speed. It would not cause an inoperative turbine. Tech Y is incorrect because having slipping clutches lead to higher engine stall speeds.
Correct answer: Oil pump pressure regulator
A problem in the oil pump or oil pump pressure regulator will cause low pressure at idle in all gear ranges.
Correct answer: A failed torque converter
A vehicle with an automatic transaxle and a properly tuned engine accelerates poorly from a stop because of a failed torque converter.
Correct answer: a stuck pressure regulator valve
A transmission with high pressure in all gears and ranges during a pressure test caused by a stuck pressure regulator valve.
Correct answer: Both X and Y
It’s true that many vibration problems are the result of an unbalanced torque converter. It’s also true that a faulty output shaft can lead to vibration. This makes both technicians correct.
Correct answer: Indirect programming
Indirect programming does not exist.
