Transmissions draw out the performance of a car
The transmission provides a comfortable drive by transmitting the optimal power from the engine to the tires. It is a vital device in the structure of an automobile. There are two types of transmissions: automatic transmissions (AT), which shift automatically, and manual transmissions (MT), which shift manually through operations carried out by the driver.
JATCO is a manufacturer of automatic transmissions, which play an invisible but important role in a vehicle.
Depending on the programming of the control software and design of a transmission system, the transmission can significantly influence the maneuverability, fuel efficiency and environmental performance of an automobile.
Transmission systems have continued to evolve in tandem with the evolution of automobiles. Among the various types of AT, the CVT, which shifts without steps through a belt and pulley system, is currently the center of attraction.
Since the torque (power) and speed of the engine are limited, the transmission ensures that the necessary torque and number of revolutions are achieved in order for the car to travel comfortably. It aids the vehicle in traveling powerfully during startup, when going uphill, accelerating quickly on highways and traveling at cruising speeds. It is also effective in helping the vehicle reverse and in breaking the engine when the vehicle goes downhill.

In addition, it offers a rich line-up of conventional step AT´s. Various vehicles that are manufactured around the world today are mounted with JATCO products, and JATCO has won the strong support and high appraisal of many customers. As a manufacturer that specializes in transmissions, JATCO aims to be the global leader going forward.
HOW CVT GEAR SHIFTING WORKS
This video will give you a simple explanation of the differences between the structure and gear shifting mechanisms of belt CVT´s (continuously variable transmissions) and traditional step-gear automatic transmissions.
Step AT
JATCO continues to research ways for the world-standard step AT to further boost fuel economy and improve drivability.
Although the use of CVT continues to grow, the step AT remains widely used in many automobiles around the world. JATCO continues to pursue research from a wide range of angles, including adding multistep and wider range for better fuel economy, weight reductions, and improved control technologies, aimed at improving the step AT's engine and environmental performance.
Transmission for Hybrid Vehicles
Commanding its advanced clutch control technologies built up over the years, JATCO is developing transmissions for the next generation of pioneering hybrid vehicles with automakers. JATCO's long-standing proprietary clutch control technologies have helped realize greater energy regeneration and motor operations as well as balance both fuel economy and drivability to a higher degree than ever before.
