Fig. 577: Torque Converter Fluid Operation

The converter impeller (driving member), which is integral to the converter housing and bolted to the engine
drive plate, rotates at engine speed. The converter turbine (driven member), which reacts from fluid pressure
generated by the impeller, rotates and turns the transmission input shaft.
TURBINE
As the fluid that was put into motion by the impeller blades strikes the blades of the turbine, some of the energy
and rotational force is transferred into the turbine and the input shaft. This causes both of them (turbine and
input shaft) to rotate in a clockwise direction following the impeller. As the fluid is leaving the trailing edges of
the turbine's blades, it continues in a "hindering" direction back toward the impeller. If the fluid is not redirected
before it strikes the impeller, it will strike the impeller in such a direction that it would tend to slow it down.
