Description
This unit describes the performance outcomes required to diagnose and repair powershift transmissions fitted to heavy vehicles. It involves diagnosing deviations from correct operation, repair operations of powershift transmissions and associated systems, and post-repair testing procedures.Licencing, legislative, regulatory or certification requirements may apply to this unit in some jurisdictions. Users are advised to check with the relevant regulatory authority.
Notes
Elements and Performance Criteria
1. Prepare to diagnose and repair a powershift transmission
  • 1.1. Workplace instructions are used to determine job requirements
  • 1.2. Workplace health and safety (WHS) requirements are observed and applied throughout the work
  • 1.3. Procedures and information are sourced and interpreted
  • 1.4. Diagnosis options are analysed and those most appropriate to the circumstances are selected
  • 1.5. Appropriate diagnostic tools and equipment are selected and prepared
2. Diagnose a powershift transmission
  • 2.1. Diagnostic tests are performed according to workplace procedures and without causing damage to components or systems
  • 2.2. Faults are identified from diagnostic test results and causes of faults are determined
  • 2.3. Diagnosis findings are reported according to workplace procedures, including recommendations for necessary repairs or adjustments
3. Repair a powershift transmission
  • 3.1. Repair options are analysed and those most appropriate to the circumstances are selected
  • 3.2. Appropriate tools, techniques and materials are selected and prepared
  • 3.3. Repairs and component replacements and adjustments are carried out without causing damage to components or systems and according to workplace procedures and manufacturer and component supplier specifications
  • 3.4. Post-repair testing is carried out according to workplace procedures and relevant legislation
4. Clean up work area and finalise work processes
  • 4.1. Final inspection is made to ensure work is to workplace expectations and vehicle is presented ready for use
  • 4.2. Tools and equipment are checked and stored according to workplace expectations
  • 4.3. Workplace documentation is processed according to workplace procedures

EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria, required Skills and Knowledge, the 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
The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy all of the requirements of the performance criteria and required skills and knowledge.
A person who demonstrates competency in this unit must be able to:
observe safety procedures and requirements
select methods and techniques appropriate to the circumstances
complete preparatory activity in a systematic manner
diagnose and repair a range of powershift transmissions
diagnose and repair heavy vehicle powershift transmissions according to workplace, manufacturer and component supplier requirements
present vehicle in a condition that complies with workplace requirements..
Context of, and specific resources for assessment
Competency is to be assessed in the workplace or a simulated workplace environment that accurately reflects performance in a real workplace setting.
Assessment is to occur:
using standard workplace practices and procedures
following safety requirements
applying environmental constraints.
Assessment is to comply with relevant:
regulatory requirements
Australian standards
industry codes of practice.
The following resources must be made available for the assessment of this unit:
workplace location or simulated workplace
heavy vehicles with powershift transmission faults relevant to the qualification being sought
equipment appropriate for the testing of heavy vehicle powershift transmissions
specifications and workplace instructions
tools appropriate for the repair, replacement and adjustment of heavy vehicle powershift transmissions.
Method of assessment
Assessment must satisfy the endorsed Assessment Guidelines of this Training Package.
Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with the application of required skills and knowledge.
Assessment methods must be by direct observation of tasks and include questioning on required skills and knowledge to ensure correct interpretation and application.
Competence in this unit may be assessed in conjunction with other units which together form part of a holistic work role.
Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate the needs of diverse clients.
Assessment processes and techniques must be culturally sensitive and appropriate to the language, literacy and numeracy capacity of the candidate and the work being performed.
