Manual transmission gear teeth are precision-engineered ridges on the gears inside a manual gearbox. These teeth interlock to transfer power from the engine to the driveshaft. Their exact shape and alignment ensure smooth gear engagement, efficient torque delivery, and dependable performance across all gear ratios. Keeping the gear teeth strong and undamaged is crucial for preventing slippage, maintaining power, and extending the overall life of the transmission.
