An automatic transmission requires a coupling between the engine’s crankshaft and the transmission’s input shaft. And while in a few special applications, like in oval track and marine setups, a direct coupler is used, the majority of all automatic transmission installations volkswagen accessories utilize accessories a torque converter. in addition to functioning as a fluid coupling between volkswagen the engine and transmission, a converter provides an additional benefit accessories through multiplying the torque input, much like a gear set. there are a number of parts in a torque converter, three of which give it the basic operating characteristics… the pump, the turbine, and the stator. the pump has rows of curved vanes arranged inside a bowl-shaped casing. the turbine is the part volkswagen that actually is responsible for turning the transmission-input shaft. like two electric fans facing each other, one with the power on, and one with the power off working in unison causing the internal rotation. when a car is just beginning to move from a dead stop the pump will be rotating much faster than the turbine. therefore the oil will accessories be working against the turbine blades with a great deal of force. in the process of passing through the stator, the direction of the flow of the volkswagen atf is reversed. if this fluid were simply allowed to re-enter the pump, it would have a tendency to work against the pump’s direction of rotation. instead the fluid accessories is forced though the stator section of the converter which uses the special shape to reverse the direction of flow.

thus oil goes back to the pump in helping the reaction of flow rather than hindering it. this adds a bit more push to the pump blades. this continuous flow of fluid between the pump and turbine through the stator brings about the factor known as torque multiplication. most people only concern themselves volkswagen with the rated stall speed and speed the torque converter clutch reacts or fluid coupling point of a torque converter. this is the speed which the engine will reach when the car''s brakes are locked and the accelerator depressed to the point where either the car will creep forward or the engine will not rev higher. unfortunately, few cars reach their potential stall speeds due to inadequate chassis, tires or brakes. just as important is the converter flash point. this is the level to which the rpm''s will actually go when the brake is released and the car begins to move. this characteristic that can be more accurate of a converter''s performance capability since in some instances accessories a vehicle will run quicker when driven from the starting line at a point above idle rather than at a maximum stall speed.
