Automatic transmission is a transmission conducting speed automatic gearshift. To change the speed automatic transmission system is used the mechanism of friction and automatic transmission oil pressure.

- 1 / L (Low) is an advanced position on the gear into one, only used when riding on extremely steep terrain.
While optional is:
- 3 is a position to go forward and the transmission will not shift in the position of top gear.
- O / D (Over Drive) is the position in order to shift gears in the transmission occurs at a higher engine speed.
