The impeller (3) is an integral part of the converter housing. The impeller consists of curved blades placed 
radially along the inside of the housing on the transmission side of the converter. As the converter housing is 
rotated by the engine, so is the impeller, because they are one and the same and are the driving members of the 
system. See Fig. 268.

The turbine (1) is the output, or driven, member of the converter. The turbine is mounted within the housing 
opposite the impeller, but is not attached to the housing. The input shaft is inserted through the center of the 
impeller and splined into the turbine. The design of the turbine is similar to the impeller, except the blades of 
the turbine are curved in the opposite direction. See Fig. 269.

The stator (1) is located between the impeller (2) and turbine (4) within the torque converter case. See Fig. 271. 
The stator contains a freewheeling clutch, which allows the stator to rotate only in a clockwise direction. When 
the stator is locked against the freewheeling clutch, the torque multiplication feature of the torque converter is 
operational.
