Abstract : With the advancement of mechanical, electronic and driver assistance technologies, the automatic transmissions have been playing a significant role in today's vehicles. In this paper, a systematic review of advanced automatic transmissions is shown Their operating principles and basic components are briefly explained, as well as the major designs existing in today’s automotive market. The paper compares the base technology torque-converter transmissions with new systems like Continuously Variable Transmissions (CVT) and Dual-Clutch Transmissions (DCT), matching differences in terms of efficiency, performance as well as maintainability. The paper also describes improvements in the driving comfort and fuel economy by means of electronic control units (ECUs) as well as sensor-triggered shift strategies. This study examines recent technological advances in automatic transmissions and their actual applications; identifies specific ways of improving vehicle performance through the development of parchment technologies; presenting a clear professional view on exactly how said parchment technology contributes to achieving better automotive performances by ATs, as well as explains our expectations for the next generation transmission technology, including AI-based g control and connect with HEV systems.
