Toyota's initial six-speed automatic transmission, the A761E, holds the title of the world's lightest in its class at 85 kg when wet. Present in Toyota/Lexus models from 2004 onward, it's an upgraded version of the A750E found in various Toyota models. Key modifications include the integration of a C4 clutch and F4 sprag in the C1 clutch drum assembly, limiting clutch-to-clutch shifting between the 5th and 6th gears. Governed by the Electronically Controlled Transmission with intelligence (ECT-i), the transmission's computer employs electronic controls to gradually adjust hydraulic pressure, ensuring smoother shifts. Moreover, ECT-i can adapt to wear and learn from driving patterns, responding to engine input conditions.
