Automatic Transmission(AT In today's automobile the automatic transmission is by far the most complicated mechanical component. It is a type of transmission that shifts itself. automatic transmission or transaxle has four basic systems-a torque converter, a gear system, a hydraulic system and an electronic system (Fig. 9-1) TORQUE CONVERTER The torque converter replaces the conventional clutch. It has three functions: 1. It allows the engine to idle with the vehicle at a standstill even with the transmission or transaxle in gear[ 1] 2. It allows the transmission or transaxle to shift from range to-range smoothly, without requiring that the driver close the throttle during the shift 3. It multiplies engine torque to an increasing extent as vehicle speed drops and throttle opening is increased this has the effect of making the transmission or transaxle more responsive and reduces the amount of shifting required
