This paper aims at to provide the improved mechanism for converting gear transmission of motorcycle from manual to automatic. Our proposed model of pneumatic actuated automatic gear and shift control uses a switch. The position of switch determines for automatic or manual transmission of motorbike. If the switch is in off-state, manual transmission is in play. Electronic Control Unit (ECU) receives respective signals from the sensors and it then activates pneumatic system. In Pneumatic system air pressure is build up which forces the piston to move up and down. We use double acting pneumatic cylinder in which air enters from the first port which generates pressure on one side and move the piston forward. From the other port air will move out and same process is followed for downward movement of piston. The proposed model discloses an Automatic gear shifting and actuation of clutch system by pneumatic system. No such device is available till date which can perform the said function. Normally the gear shifting and actuation of clutch are done manually, and in previous inventions the clutch is automatic and gear shifting is done manually, and they are using CVT clutch.
