25 June 2025 | Leave a comment Characteristics of the eight-speed automatic transmission Aisin The Aisin AW30-8L80 eight-speed automatic transmission has become widely used in many cars after the 2010s. Advantages: * Smooth Shifting: More gears provide smoother acceleration and more precise gear ratio selection for optimal efficiency. *Improved Fuel Economy: More gears allow the engine to operate at lower speeds, which reduces fuel consumption. * Improved Acceleration: Greater gear density results in quicker shifts and faster acceleration. * Extended service life: Eight gears distribute the load on the transmission, which increases its service life. Peculiarities: * Planetary Design: The Aisin gearbox has three planetary gears and five clutches for selecting gears. * Adaptive Shift Algorithm: The transmission uses an Adaptive Shift Algorithm that automatically adjusts according to driving conditions. *Hydraulic Torque Converter: The transmission uses a torque converter to keep the vehicle moving smoothly from a standstill. *Control system: The transmission is controlled by an electronic control unit (ECU), which monitors various engine and transmission parameters. Application: The Aisin AW30-8L80 eight-speed automatic transmission is used in a variety of cars of different brands, including: *Toyota * Lexus *Mazda * Subaru * BMW * Audi *Chrysler * Jeep Restrictions: *Higher Cost: Eight-speed automatic transmissions are typically more expensive to produce than transmissions with fewer gears. *More complex repairs: More gears can lead to more complex and costly repairs.
