Transmission gears wear out and start slipping.
Over time gears can wear out – especially if they have been running hot and inefficiently due to lack of or worn out transmission fluid. Slipping gears are usually due to normal wear and tear, which causes them to not engage properly and to slip in and out of sync.

Why does my car jerk when shifting gears with an automatic transmission?
Automatic transmissions that shift hard, jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low. In manual transmission vehicles, abnormal gear shifts could indicate damaged gear synchros, worn clutches or other, more severe issues.
Is Thicker oil better for gearbox?
Higher-viscosity gear oils offer thick films, better wear resistance and protection from corrosion, making them suited to slower gearboxes that operate under more intense pressures and loads.
What causes a noisy gearbox?
Bearing, gear and shaft wear are the most common causes of noise. As gear tooth faces and bearing races wear, they develop groves and small pits. While these are only small at first, they will gradually become larger, and as they grow, these imperfections will cause even more noise to occur.
