The torque converter transmits and multiplies torque. The torque converter is a four-element device:
impeller assembly
turbine assembly
reactor assembly
clutch and damper assembly
The standard torque converter components operate as follows:
The rotation of the converter housing and impeller set the fluid in motion.
The turbine reacts to the fluid motion from the impeller, transferring rotation to the geartrain through the input shaft.
The reactor redirects fluid going back into the impeller, allowing for torque multiplication.
The clutch and damper assembly dampens powertrain torsional vibration and provides a direct mechanical connection for improved efficiency.
Power is transmitted from the torque converter to the planetary gearsets and other components through the input shaft.

Another thing to realize is that the slippage of the T/C allows the engine to get into the position/range of the torque curve sooner, where the engine is therefore developing more torque. There comes a point where the T/C is in theory locked at a certain engine RPM; this is known as stall speed. Do not confuse this idea with a locking T/C used in modern and even older T/C's. The electronic lock on such converters is just that, full lock and no slippage. This replicates a manual tranny in that there is no slippage, and thus gas mileage goes up.
