A compact pneumatic gear shifting system that replaces manual lever effort with a double-acting air cylinder controlled by a 5/2 solenoid valve. Compressed air from a 12 V compressor + tank is cleaned and regulated by an FRL unit before actuating the cylinder, which pushes/pulls the gearbox selector through a linkage. Flow controls tune shift speed, while a quick-exhaust valve dumps air for rapid reversals. Limit/proximity sensors confirm gear positions and feed a small Arduino/ECU, enabling interlocks (neutral check, RPM window) and buttons/joystick operation. A pressure gauge, relief valve, fuse, and E-stop/manual override keep the system safe and serviceable. Ideal for automobile/mechatronics projects, it demonstrates real-world integration of pneumatics, sensors, and control logic for fast, repeatable shifts with reduced driver effort.
