Performance Evidence

Before competency can be determined, individuals must demonstrate they can perform the following according to the standards defined in this unit’s elements, performance criteria, range of conditions and foundation skills:

diagnose and repair a fault in two different machines with continuously variable transmissions

remove, refit or replace one of the above transmissions.

Knowledge Evidence

Individuals must be able to demonstrate knowledge of:

work health and safety (WHS) and occupational health and safety (OHS) requirements relating to diagnosing and repairing continuously variable transmissions, including procedures for:

tagging out and isolating machines, and wheel chocking

working with high pressure fluid hazards

using lifting, jacking and supporting equipment

environmental requirements, including procedures for trapping, storing and disposing of hydraulic fluid released from transmissions

operating principles of continuously variable transmissions and associated components, including:

hydrostatic systems

countershaft transmissions

planetary transmissions

transmission control valves and solenoids

hydraulic circuits and schematics

electronic control system

application, purpose and operation of continuously variable transmissions and components, including:

power flows, including compound planetary transmissions

diagnostic testing procedures for continuously variable transmissions that comply with manufacturer specifications, including:

accessing and interpreting scan tool system data, including:

diagnostic trouble codes (DTCs)

live data

freeze frame data

waveforms

repair procedures for continuously variable transmissions, including procedures for removing, replacing and adjusting them

post-repair testing procedures for continuously variable transmissions.

Assessment Conditions

Assessors must satisfy NVR/AQTF assessor requirements.

Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.

Assessment must include direct observation of tasks.

Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the continuously variable transmissions that they have worked on, e.g. repair orders.

Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.

The following resources must be made available:

automotive repair workplace or simulated workplace

workplace instructions

manufacturer continuously variable transmission specifications

two different machines with continuously variable transmission faults

diagnostic equipment for continuously variable transmissions

tools, equipment and materials appropriate for repairing and adjusting continuously variable transmissions.
