Application
This unit describes the performance outcomes required to inspect and service automatic transmissions. It involves preparing for the task, inspecting the transmission, reporting the inspection findings, servicing and adjusting the transmission, and completing workplace processes and documentation.
It applies to those working in the automotive service and repair industry. The automatic transmissions include those of agricultural machinery, heavy commercial vehicles, light vehicles, marine vessels, mobile plant machinery, motorcycles or outdoor power equipment.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

types and applications of transmission fluids
inspection procedures for automatic transmissions, including:
fluid levels and condition
fluid leaks
internal and external physical condition
transmission sensors and controls
service and adjustment procedures for automatic transmissions, including:
replacing transmission fluid and filter
checking transmission fluid levels
adjusting bands, linkages and sensors as required
post-service testing procedures for automatic 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 automatic 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 automatic transmission specifications
two different vehicles or machinery with automatic transmissions requiring servicing
tools, equipment and materials appropriate for inspecting and servicing automatic transmissions.
