Driveline mechanics at Motorholics Seven Hills


As the engine operates, it creates a turning effort called torque which is used to rotate the car's wheels.


A transmission and driveline system is needed to connect and transfer the drive torque from the engine's crankshaft to the wheels. A number of components make up the vehicle's driveline including the gearbox, automatic transmission, transfer case, driveshaft/s, differential assembly, axles and hubs. These systems incorporate an extensive number of bushes, bearings and seals.


Our expert technicians can dismantle, recondition and overhaul your gearbox. We can supply and fit exchange gearboxes and transmissions completely rebuilt with new parts.  When fitted with a reconditioned transmission or gearbox from Motorholics your vehicle will again drive and shift gears as new.


We perform all types of driveline repairs including:


  • Automatic transmission

  • Transmission servicing

  • Reconditioned transmissions

  • Diagnostic checks

  • Torque converter

  • Valve body assemblies

  • Manual gearboxes

  • Rebuilt gearboxes

  • Transfer case

  • Differential

  • CV joints / CV boots

The life expectancy of a vehicle transmission can also be affected by many factors: driving habits, distance travelled each year, hauling and towing heavy loads, overheating and leaking fluid.
