This paper is based on the project “Power Assisted Gear Shifting Mechanism for Automobiles”. This is a design, fabrication and implementation project. The project provides solution for gear shifting for the cars. The passenger cars that now ply on the road have transmission either of manual or automatic type of gear changing. The manual type of transmission is preferred for the perfect performance without a loss in power but a compromise for comfort ness. In this type automatic system of power transmission there is easiness of gear shifting but there is a definite loss of power and mileage.

The main objective of this project is to create a mechanism to reduce the inconvenience caused when changing gears in the car. The gear shifting here is by mere pressing of feather touch buttons present on the dash board. The gear shifting is by hydraulic force achieved by a simple modification to the gear box. The setup consists of power steering pump, piston cylinder assembly and a set of fluid valves. This project if implemented is a clear alternative for the Automatic transmission because of its low cost and ease of use. Moreover the whole set up is small and requires a very small space. This can sure be a standard fitment if proper marketing strategy is carried out. Further, automatic clutch can be incorporated with this unit to make it fully automatic.

The paper deals with the real time project, Power Assisted Gear Shifting Mechanism for Automobiles which was done in the academic year 2004- 2005. The paper deals with the various design aspects of the creation of this project. This project is aimed at giving driver the convenience for gear shifting.
