Task E-22 Services, diagnoses and repairs manual transmissions and transfer cases
Task Descriptor
The transmission of a vehicle transfers power from the engine through the drive shaft to the wheels to enable movement of the vehicle. The transmission allows for selection of gear ratios needed for various loads and speed conditions. The transfer case allows transmission power to be directed to components such as additional axles and accessories.
Truck and transport mechanics diagnose, service and repair transmission and transfer cases minimizing down time of the vehicle, and ensuring the safety of the vehicle, driver and public. Servicing includes routine maintenance.
