Abstract: In this study, a gear shifting mechanism was designed and applied to make the shifting process faster and less destructible for the driver. The new device must be reliable, has a small dimensions, low construction and maintenance cost. This paper aims to improve gear shifting process using devices as: a manual four stroke engine bike, two solenoid actuator, Programmable Logic Controller (PLC), limit switches, push buttons, indicators, and power supply. According to suggested gear_ shifting method the control unit chooses optimum gear shifting ratio for an automobile without operating it manually (using relays). Using this method leaves to the driver the excitement of choosing the shifting moment. A solenoid actuated transmission shifting apparatus is provided for temporary or permanent installation in automobiles with conventional, H-pattern-type manual transmissions or automatic transmissions and for use with motorcycle transmissions. The shifting apparatus allows for both upshifting and downshifting through the transmission gears by pressing pushbuttons mounted on the Steering wheel, “handlebar†or dashboard. A solenoid shift actuator for a transmission, which actuates, in a direction of shift, a shift lever for operating a synchronizing device of the transmission, the shift actuator comprising a first electromagnetic solenoid and a second electromagnetic solenoid for actuating an operation member coupled to the shift lever in the directions opposite to each other. Each of the first electromagnetic solenoid and the second electromagnetic solenoid comprises a casing, a fixed iron core disposed in the casing, a moving iron core arranged to be allowed to approach, and separate away from, the fixed iron core, an operation rod mounted on the moving iron core to engage with the operation member, and an electromagnetic coil arranged between the casing and the fixed iron core as well as the moving iron core
