What transmission is used in the BMW E90?

E90's 320 imported version uses the GA6L45R transmission manufactured by Aisin, while the domestic version uses ZF's GA6HP19. Introduction to transmission: Transmission, also known as gearbox, is an automotive component used to change the speed and torque from the engine, and can fix or change the gear ratio between the output shaft and input shaft. Principle of transmission: Manual transmissions mainly consist of gears and shafts, achieving speed and torque changes through different gear combinations; while automatic transmissions consist of torque converters, planetary gears, and hydraulic control systems, achieving speed and torque changes through hydraulic transmission and gear combinations.
I've driven a BMW E90 for several years. Its transmission primarily uses the ZF 6-speed automatic gearbox, which is quite intelligently designed. It shifts smoothly in urban driving without noticeable jerking. During long-distance trips, it responds quickly and automatically adjusts gears based on throttle input, making it relatively fuel-efficient. There's also an optional manual transmission version that offers a more direct driving experience, suitable for those who enjoy handling. In terms of maintenance, this transmission has good durability, but after 100,000 kilometers, it's important to pay attention to the oil change interval to avoid leakage issues. Many E90 owners enhance performance through second-hand modifications, such as installing cooling systems, which makes me feel it's both practical and fun to drive. Overall, it's very trustworthy.
