4-Speed Automatic Transmission – 3D Model SolidWorks UG(NX)

Automatic transmission advantages: low cost, strong practicality, mostly installed in small and compact cars Disadvantages: slightly poor fuel consumption and comfort. Compared with those 5-speed or 6-speed mechanical automatic transmissions, the 4-speed automatic transmission has only 4 sets of gears and a simpler structure, which can actually meet the needs of most people. However, the 4-speed automatic transmission has an obvious disadvantage, that is, the smoothness of the power output of the transmission is average, and the comfort is not satisfactory if the throttle is slightly larger, and the fuel consumption is not very ideal. Of course, all these shortcomings will be covered by the cost performance. Therefore, for models around 100,000 or less, the 4-speed transmission is a very common equipment.
