  • apply oral communication skills sufficient to convey information and concepts to customers
  • apply planning and organising skills to own work activities, including making good use of time and resources, sorting out priorities and monitoring own performance
  • interact effectively with other persons both on a one-to-one basis and in groups, including understanding and responding to the needs of a customer and working effectively as a member of a team to achieve a shared goal
  • establish safe and effective work processes which anticipate and/or resolve problems and downtime, to systematically develop solutions to avoid or minimise reworking and avoid wastage
  • use mathematical ideas and techniques to correctly calculate time, assess tolerances, apply accurate measurements, calculate material requirements and establish quality checks
  • use workplace technology, including the use of measuring equipment, computerised technology and communication devices and the documenting/recording of results

Required knowledge 

A working knowledge of:

  • WHS regulations/requirements, equipment, material and personal safety requirements
  • dangers of working with transmissions
  • operating principles of automatic and semi automatic transmissions and their relationship to other systems
  • types and layout of service/repair manuals (hard copy and electronic)
  • diagnostic procedures
  • repair and/or replacement procedures

Evidence Guide


The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

It is essential that competence in this unit signifies ability to transfer competence to changing circumstances and to respond to unusual circumstances in the critical aspects of:

  • observing safety procedures and requirements
  • communicating effectively with others involved in or affected by the work
  • selecting methods and techniques, appropriate to the circumstances
  • completing preparatory activity in a systematic manner
  • interpreting diagnosis results
  • conducting repair and/or replacement of a range of transmissions in accordance with workplace and manufacturer/component supplier requirements
  • completing work within workplace timeframes
  • vehicle/transmissions presentation to customer in compliance with workplace requirements

Context of , and specific resources for assessment 

Application of competence is to be assessed in the workplace or simulated worksite

Assessment is to occur using standard and authorised work practices, safety requirements and environmental constraints

Assessment is to comply with regulatory requirements, including Australian Standards

The following resources should be made available:

  • workplace location or simulated workplace
  • material relevant to carrying out repairs to automatic and semi-automatic transmissions and associated components
  • equipment, hand and power tooling appropriate to carrying out repairs to automatic and semi-automatic transmissions and associated components
  • activities covering mandatory task requirements
  • specifications and work instructions

Method of assessment 

Assessment must satisfy the endorsed assessment guidelines of the automotive industry's RS&R Training Package

Assessment methods must confirm consistency and accuracy of performance together with application of underpinning knowledge

Assessment must be by direct observation of tasks, with questioning on underpinning knowledge and it must also reinforce the integration of key competencies

Assessment may be applied under project related conditions and require evidence of process

Assessment must confirm a reasonable inference that competence is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances

It is preferable that assessment reflects a process rather than an event and occurs over a period of time to cover varying quality circumstances. Evidence of performance may be provided by customers, team leaders/members or other persons subject to agreed authentication arrangements

Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role
