Quality controller

A vehicle with an automatic transmission shudders with light throttle at a steady cruise, around 75-85 km/hr.

what could be the possible cause?

• Differential slipping

• Output shaft slipping

• Roller clutch slipping

• Torque converter clutch slipping

How do the multiple displacement system (MDS) functions?

• Both valves do not open and fuel is shut off

• Fuel is shut off to random cylinders

• The intake valve does not open and fuel is shut off

• The exhaust valve does not open and fuel is shut off

When in 4WD, the axles of a part-time transfer case are:

• Mechanically locked together

• Connected through a clutch

• Slipping depending on the duty cycle

• Connected through a center differential

Which of the following should be done before road testing a vehicle with a vehicle-speed-related concern?

• Inspect tires for abnormal wear

• Check the propeller shaft operating angles

• Calculate propeller shaft frequency

• Determine the frequency of the vibration

Which test identifies the vehicle speed at which the noise or vibration occurs?

• Engine accessory test

• Downshift speed test

• Slow acceleration test

• Neutral coast down

If the TCC remains applied as the vehicle comes to a stop,

What will occur?

• One of the braking clutches is released

• The engine will stall

• Nothing, this is a normal operation

• The engine idle will increase

What is required before performing any repairs for an NVH concern?

• Duplicate the customer concern

• Engine accessory test

• Measure driveline operating angles

• Engine loaded test

Which of the following is NOT part of the pre-road test inspection?

• Look for cupping, flat spots, feathering, and shoulder wear.

• Ensure the tire is the proper application for the vehicle.

• Ensure the tire is inflated to specification.

• Check the propeller shaft operating angles.

During a road test, a technician notices a grinding noise at 55 mph. What is the next step?

• Calculate engine accessory frequency

• Determine related symptoms

• Perform a downshift speed test

• Determine the amplitude of the vibration

Adaptive cruise control (ACC) can______

• Automatically adjust the distance between the vehicle and the vehicle in front based on the speed of travel

• Allow a driver to set the desired following distance between their vehicle and the vehicle in front

• Change the following distance between the vehicle and the vehicle ahead based on the type of road surface and whether it is dry, wet or icy

• All of the above
