Transmission oil can play a role in cleaning and lubricating the gearshift system, and can also extend the life of the transmission device.

Transmission fluids are classified into automatic transmission fluids (ATF) and manual transmission fluids according to the differences in automobile transmissions. The shelf life of unopened gearbox oil is generally 2-3 years for manual gearbox oil and 6 years for automatic gearbox oil if it is not exposed to the sun or high temperature.
