Elements and Performance Criteria

1. Assess converter/transmission operation
   • Torque converter, simple and compound planetary gearing, and hydraulic control operating principles are understood.
   • Relevant information is obtained and is correctly interpreted prior to any testing.
   • Preliminary checks are undertaken safely and to prescribed procedures.
   • Faults are correctly isolated to component level and appropriate corrective action is determined.
   • Test equipment is adapted and used correctly.
   • Component parts are correctly assessed for reuse or replacement.
2. Repair/replace faulty components
   • Component wear and clearances are correctly determined using appropriate test equipment and manufacturers' recommendations.
   • Replacement components are correctly selected using manufacturers' data.
   • Components are removed and refitted to converter/transmission assembly following prescribed procedures.
   • Adjustments are made correctly using appropriate tooling/equipment and manufacturers' data.
   • Test and rectification activities are accurately recorded.
   • Converter/transmission assembly is free of excessive noise and operates to specification after repair work is carried out.

Required Skills

Required skills

Look for evidence that confirms skills in reading interpreting and following information on written job instructions specifications standard operating procedures charts lists drawings and other applicable reference documents planning and sequencing operations checking taskrelated information checking for conformance to specification identifying faulty automatic transmission components checking the automatic transmission for correct operation using test equipment correctly testing the transmission components for conformance to specification identifying component parts for reuse or replacement removing and refitting components to the automatic transmission assembly adjusting automatic transmission components using appropriate tools techniques and equipment recording test and rectification activities identifying replacement components using manufacturers data operating the automatic transmission assembly free of excessive noise and in conformance to specifications undertaking calculations and numerical operations within the scope of this unit

Evidence Required

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	A person who demonstrates competency in this unit must be able to diagnose and rectify automatic transmissions Competency in this unit cannot be claimed until all prerequisites have been satisfied
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria including required knowledge and be capable of applying the competency in new and different situations and contexts
Context of and specific resources for assessment	This unit may be assessed on the job off the job or a combination of both on and off the job Where assessment occurs off the job that is the candidate is not in productive work then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team The assessment environment should not disadvantage the candidate This unit could be assessed in conjunction with any other units addressing the safety quality communication materials handling recording and reporting associated with diagnosing and rectifying automatic transmissions or other units requiring the exercise of the skills and knowledge covered by this unit
Method of assessment	Assessors should gather a range of evidence that is valid sufficient current and authentic Evidence can be gathered through a variety of ways including direct observation supervisors reports project work samples and questioning Questioning techniques should not require language literacy and numeracy skills beyond those required in this unit of competency The candidate must have access to all tools equipment materials and documentation required The candidate must be permitted to refer to any relevant workplace procedures product and manufacturing specifications codes standards manuals and reference materials

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
