What an assessment for AURTTX008 must cover

34 assessable components: 5 elements (22 performance criteria), 1 performance evidence and 4 knowledge evidence requirements, plus 7 foundation skills. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Elements & performance criteria

1 Prepare to dismantle manual transmission

1.1Job requirements are determined from workplace instructions
1.2Dismantling information is sourced and interpreted
1.3Dismantling options are analysed and those most appropriate to the circumstances are selected
1.4Hazards associated with the work are identified and risks are managed
1.5Dismantling tools and equipment are selected and checked for serviceability

2 Dismantle and evaluate manual transmission and components

2.1Transmission is dismantled in a logical sequence according to manufacturer and workplace procedures, and safety and environmental requirements, and without causing unnecessary damage to components or systems
2.2Components are cleaned for evaluation according to workplace procedures and safety and environmental requirements
2.3Components are measured and compared with manufacturer specifications and serviceability is determined
2.4Component repair method is determined
2.5Unserviceable parts are identified and replacement parts sourced

3 Carry out overhaul

3.1Overhaul information is sourced and interpreted
3.2Overhaul options are analysed and those most appropriate to the circumstances are selected
3.3Overhaul tools and equipment are selected and checked for serviceability
3.4Components are machined, repaired and replaced as required, and adjustments are carried out according to manufacturer specifications, workplace procedures, and safety and environmental requirements, and without causing damage to components or systems

4 Assemble transmission and components

4.1Transmission is assembled according to manufacturer specifications, workplace procedures, and safety and environmental requirements
4.2Tolerances and clearances are measured against manufacturer specifications and necessary adjustments are made
4.3Assembly of transmission is completed within workplace timeframes and without causing damage to other components or systems
4.4Post-assembly testing is carried out according to workplace procedures and safety and environmental requirements, and any problems detected as having been introduced during the assembly process are rectified

5 Complete work processes

5.1Final inspection is made to ensure work is to workplace expectations and transmission is presented ready for use or storage
5.2Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected
5.3Tools and equipment are checked and stored according to workplace procedures
5.4Workplace documentation is processed according to workplace procedures

Performance evidence

overhaul three different manual transmissions, one of which must include a transaxle transmission.

Knowledge evidence

Questions about assessing AURTTX008

What does an assessment tool for AURTTX008 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for AURTTX008 needs to address all 34 unit components: 5 elements with 22 performance criteria, 1 performance evidence requirements, 4 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for AURTTX008?

Auditori pulls the current release of AURTTX008 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for AURTTX008 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing AURTTX008 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of AURTTX008, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
