Context and Conditions of Assessment
This assessment will ensure that the elements, performance criteria, performance evidence and knowledge evidence required and conditions are adhered to demonstrate competency in this unit assessment task. ● Read the assessment carefully before commencing.
Re-Assessment Conditions
● If the evidence is graded as NS – Not Satisfactory you will be required to re-submit the evidence. In this case, you will be provided with clear and constructive feedback based on the assessment decision so that they can improve your skills / knowledge prior to reassessment. o If a student is deemed NYC in the reassessment or if the student did not approach the AIBT’s within five working days with a valid reason for not availing themselves of the reassessment

oIf the student is found to be plagiarising or cheating again after conclusion of the Intervention meeting with the Course Co-ordinator, the matter will be referred to the Academic Management Committee which may result in the suspension or cancellation of their enrolment
oAIBT’s has intervention strategies, including student support services available to enable students to complete qualification in the expected time frame. Students at risk of not completing within this time frame are identified as early as possible and an intervention strategy is put in place.

AIBT will ensure access to:




Your assessor will be looking for the following in this assessment task: -

25. What does a milky coloured ATF indicate?

Dark, cloudy, creamy, milky or opaque transmission fluid is a sign of a problem with the transmission. Sometimes this is caused by coolant being forced into the transmission by a fault radiator

cause Slippage between shifts. Air in the pressure Regulator valve will cause a Buzzing noise when the

valve tries to regulate Pump pressure.

A. Allow the valve to expand
B. Allow the sliding of valve in the guide
C. Ensure that the valve closes fully
D. Ensure that the crankshaft is free to rotate

28. Complete the following statement about electronic automatic transmissions using the following words.

Comfort. Although these transmissions Function in the same way as earlier Hydraulically based

30. The EPC (electronic pressure control) solenoid is duty-cycle-controlled by the TCM.

True or False: True

The Electronic control system for Honda’s CVT consists of a TCM, various sensors, linear solenoids, and an Inhibitor solenoid. Pulley ratios are always Controlled by the control system. Input from the various sensors determines which Linear solenoid the TCM will activate. Activating the shift control solenoid changes the Shift control valve pressure, causing the shift valve to Move. This changes the Pressure applied to the driven and drive Pulleys, which change the effective pulley Ratio. Activating the start Clutch control Solenoid moves the start clutch valve. This valve Allows or disallows pressure to the start clutch Assembly When pressure is applied to the clutch, Power is transmitted from the pulleys to the final Drive gear set.

33. The Honda CVT transmission does not have a torque converter. Honda use a start clutch to get the vehicle moving without stalling or straining the engine.

1 By position-inboard or outboard

2 By design-ball type or tripod

A. Uniform torque transfer
B. Operation through a wide range of angles
C. Constant speed
D. All answers are correct

39. What is the difference between a fixed CV-joint and a plunge type joint?

	AURLTX104 Diagnose complex faults in light vehicle automatic transmission and driveline systems

True or False: True

44. What is meant by U-joint phasing?

Phasing is the process of aligning the universal joint yokes on both ends of the drive shaft in a parallel fashion. If the joints are not properly phased, they will operate at varying speed throughout each revolution which can cause second order vibrations

47. Complete the following statement about rear wheel drive shaft’s using the following words.

	AURLTX104 Diagnose complex faults in light vehicle automatic transmission and driveline systems

True or False: True

50. Axles with a numerically high gear ratio such as 4.11 allow the engine to run slower at any given speed, resulting in better fuel conservation.

True or False: True
