Specifications

The A340E transmission is a robust and time-tested 4-speed automatic transmission engineered by Toyota for dependable performance in rear-wheel and all-wheel-drive vehicles. Designed to handle the demands of 6-cylinder engines and early V8 applications, it delivers smooth, consistent shifting through its electronically controlled system with integrated solenoids. Its well-balanced gear ratios including a strong 2.804:1 first gear for acceleration and a 0.705:1 overdrive for efficient cruising ensure both responsive power delivery and improved fuel economy. 

The inclusion of a lock-up torque converter further enhances efficiency by reducing slippage at higher speeds. Built for durability, the A340E operates with ATF Type T-II fluid and has a capacity of 8.3 liters, supporting reliable thermal management and long service life. With precise hydraulic performance, controlled line pressures, and quick engagement times, this transmission remains a trusted choice for drivers and builders seeking a proven, high-quality automatic gearbox.
