Mustang Cobra V8-281 4.6L DOHC VIN V MFI (1997)
an electronic pressure control (EPC) solenoid in the main control valve body.
IMPELLER AND COVER
The primary functions of the impeller and cover assembly are to drive the impeller blades, contain hydraulic fluid and provide a mating surface for
the converter clutch pressure plate. In addition, the impeller hub drives the fluid pump gear.
TURBINE
The turbine is a sectioned, donut-shaped steel stamping that is splined to the input shaft. It is driven by fluid from the impeller and transmits this
power to the geartrain. Because of its basic shape, the turbine automatically directs fluid back to the impeller.
REACTOR
The stator, also called the reactor redirects the fluid flow returned to the impeller from the turbine so that the fluid moves in the same direction as
engine/impeller rotation. This action aids in torque multiplication because it adds torque to that already supplied by the engine. The stator contains
a one-we, clutch which holds it stationary when torque multiplication is necessary, but allows freewheeling at higher speeds when torque
multiplication is not necessary.
TORQUE CONVERTER CLUTCH
The pressure plate attaches to the back of the turbine and can be applied against the cover to allow for a mechanical transfer of engine torque to the
geartrain. This occurs mainly in third and fourth gears when torque multiplication is no longer necessary. (Converter clutch application may also
occur in second gear under certain conditions.)
The pressure plate works much like a regular mechanical clutch. Apply, release and controlled slip of the clutch are controlled by opposing fluid
forces on each side of the pressure plate.
