Acts as a fluid

coupling between the
engine and transmission geartrain.
P
rovides multiplication of engine torque.
Cons

ists of an impeller, turbine and stat
or, housed within a converter cover.
Has a l
ock-up clutch with variable slip control.
The transmission casing:
Houses the geartrain and elec t
ro-hydraulic control unit.
Contains

the input speed sensor which measures turbine speed.
Contai

ns the output speed sensor which measures the transmission output speed.
