Torque Converter: Operation: Notes
WARNING: This page is about a different car, the 2004 Dodge Sprinter. However, it is still accessible from the selected car via links, so may be relevant.
The converter impeller (driving member) (2) (Fig 1 ), which is integral to the converter housing and bolted to the engine drive plate, rotates at engine speed. The converter turbine (driven member) (1), which reacts from fluid pressure generated by the impeller, rotates and turns the transmission input shaft (4).
