The variety of transmissions available in the market today has grown exponentially in the last 15 years, all while increasing in complexity. The effect is certainly that we are now dealing with a varied amount of transmission types including manual, regular automatic, automated manual, dual clutch, continually variable, split power and real EV.
Until very recently, automotive vehicle manufacturers largely had two types of transmitting to choose from: planetary automatic with torque converter or conventional manual. Today, nevertheless, the volume of choices available demonstrates the adjustments seen over the industry.
This is also illustrated by the countless various kinds of vehicles now being manufactured for the market. And not merely conventional vehicles, but also all electric and hybrid vehicles, with each type needing different driveline architectures.
The traditional advancement process involved designing a transmission in isolation from the engine and the rest 
of the powertrain and vehicle. Nevertheless, this is changing, with the restrictions and complications of this method becoming more widely recognized, and the continuous drive among manufacturers and designers to provide optimal efficiency at reduced weight and cost.
New powertrains feature close integration of elements like the primary mover, recovery systems and the gearbox, and also rely on highly sophisticated control systems. This is to make certain that the best amount of efficiency and overall performance is delivered all the time. Manufacturers are under improved pressure to create powertrains that are brand new, different from and much better than the last version-a proposition that’s made more complex by the necessity to integrate brand elements, differentiate within the marketplace and do it all on a shorter timescale. Engineering teams are on deadline, and the development process must be more efficient and fast-paced than previously.
Until now, the use of computer-aided engineering (CAE) has been the most typical way to build up drivelines. This technique involves elements and subsystems designed in isolation by silos within the organization that lean toward confirmed component-level analysis equipment. While they are highly advanced equipment that enable users to extract very dependable and accurate data, they remain presenting data that is collected without thought of the complete system.
