How Many Liters of Transmission Fluid Should Be Added at Once?

[McRiver]

Gravity oil change requires 3~4L of fluid, while a machine flush requires 12L. Below are specific details about automotive transmissions: 1. Definition: A transmission is a gearbox that alters the gear ratio and direction of motion. It is located between the clutch and the central drive. 2. Function: Under constant engine speed and torque, it changes the vehicle's driving force and speed (shifting); allows the vehicle to move in reverse (direction change); and enables the engine to idle without stalling (neutral gear). 3. Transmission Types: Gear-type transmissions can be categorized into three types: dual-shaft, triple-shaft, and compound. Dual-shaft transmissions have two main shafts (excluding the reverse shaft) and achieve speed reduction through a single pair of gears. Triple-shaft transmissions have three main shafts (input shaft, countershaft, and output shaft) and achieve speed reduction through two pairs of gears. Compound transmissions consist of two gearboxes connected in series or parallel to obtain more gear ratios with fewer gears.
