01Core Units: Working Safely and Competently on Heavy Commercial Vehicles
The 22 core units build the foundation every heavy commercial vehicle (HCV) technician must hold before specialising. They cluster into five areas: workplace safety (hazard identification, risk control, personal protective equipment, isolation and lock-out, working at heights and under raised vehicles); environmental and sustainability practice (waste segregation, spill containment, refrigerant and oil recovery, correct disposal of batteries and filters); tools and equipment (hand tools, torque wrenches, lifting and jacking equipment, measuring instruments, pre-start checks on workshop plant); technical fundamentals (fasteners and torque, bearings and seals, lubrication, cooling, electrical basics, hydraulic and air systems, wheels and tyres); and communication and documentation (job cards, parts interpretation, service records, customer handover, teamwork).

Manual transmissions in heavy commercial vehicles are constant-mesh gearboxes with sliding clutches or synchromesh on some ratios, often twin countershaft designs to share torque load. You must understand the power flow from clutch to input shaft, countershaft, main shaft and output, and how gear selection engages dogs or synchro cones.

Heavy vehicle automatics include torque-converter planetary automatics, automated manual transmissions (AMT) and continuously variable or hydrostatic drives in specialist applications. You must understand torque converter operation (impeller, turbine, stator, lock-up clutch), planetary gear sets and clutch/brake bands, hydraulic control via valve body and solenoids, and electronic control through the transmission control module (TCM) using speed, throttle and temperature inputs.
