What should be avoided to ensure the longevity of a manual transmission?

To ensure the longevity of a manual transmission, over-revving the engine in lower gears should be avoided. When the engine is pushed beyond its recommended RPM range in lower gears, it can lead to excessive wear and tear. This scenario places a significant strain on the transmission components, such as the gears and synchronizers, which can result in premature failure. Over-revving can also cause the clutch to slip or wear out faster, as it may struggle to engage properly during these high-stress conditions.

On the other hand, regularly changing the oil helps maintain proper lubrication and reduces friction, which is crucial for the health of the transmission. Practicing smooth driving techniques promotes better control and minimizes stress on the transmission system. Engaging the clutch gently is important to prevent shock loading and to ensure that components mesh smoothly. All of these practices contribute positively to the overall lifespan of a manual transmission.
