Drivetrain is the core components of automobile.Its task is transforming and regulateing the performance of engine. Transmission can effectively and economically conveyed the power to the wheel which can meet the requirement of vehicles. It is used to change the engine's torque spread and wheel speed. Aim is to work in a variety of conditions，different vehicle traction and speed，so that the car has good power and fuel economy。The transmission of the structure of the manipulation of car shift required reliability and portability, transmission stability and efficiency will have direct influence. Therefore, the design of transmission quality has been the focus of competition in the automotive industry. This paper studies the two shafts type design six manual shift transmission,By Rachel G52010 paragraph messi version 2.0 wenqi TCI automobile vehicle parameters and engine parameters for the design basis, the design of manually transmission.At first, I will give a summary of the current situation and the tendency of development of the vehicle transmission, and introduce the latest development state in the field of the transmission.The second, I will compare the transmitting scheme of different transmission, and choose a better structure scheme.Next, I will do some mechanic analyses, strength, stiffness check of the shafts and gears, which are the important parts of the transmission, and choose appropriate materials and heat treatment.At last, I will introduce the operation mechanism and the synchronizer, which plays an important role in changing gear. I will give an account of the type, operation, design procedure and major parameter of the synchronizer.At the supplement, I will write some thing like formula, tableau graph and so on. It may be helpful for the future design. Key words:Transmission；Transmission Ratio；Gear；Axis；Check. II
