The basics of your drivetrain.

Internal-combustion engines run at high speeds, so a reduction in gearing is necessary to transmit power to the drive wheels, which turn much more slowly.


The gearbox provides a selection of gears for different driving conditions: standing start, climbing a hill, or cruising on level surfaces. The lower the gear, the slower the road wheels turn in relation to the engine speed.


The gearbox is the second stage in the transmission system, after the clutch. It is usually bolted to the rear of the engine , with the clutch between them.



Mayfair Gearbox caters for everything from a simple single
passenger vehicle gearbox repair to the upkeep of multi-vehicle commercial and industrial fleets - no job is too big or too small.

We pride ourselves on top quality technical work across the board, ensuring our staff complement are constantly updated with the latest technical knowledge and training.


Mayfair Gearbox is Level 2 BBBEE Certified and is the largest black-owned South African gearbox company.
