Truck automatic vehicle transmission

Engine Brake Performance is Improved in Addition to Fuel Efficiency and Dynamic Performance The automatic transmission controls the amount of continuous slip of lock-up clutch to reduce energy loss caused during shifting. When an accelerator pedal is released, the optimum downshifting is automatically done according to vehicle weight and road gradient, providing improved engine brake performance. Neutral control, a function which reduces engine load at idling, decreases fuel injection quantity during idling. The number of parts is reduced compared with a 4-speed automatic transmission, offering a compact design (compared with conventional AISIN products).
