A torque converter is generally a type

of fluid coupling capable of producing

torque.

Replacement of clutch for automatic

transmission vehicle.

Impeller-Connected to the flywheel and

towards the gearbox

Turbine-Facing the impeller and the main

shaft of the gear box is taken from the

turbine through the impeller.

Stator-Between the impeller and turbine

Stall-The prime mover is applying power to

the impeller but the turbine cannot rotate.

Acceleration- The load is accelerating but

there still is a relatively large difference

between impeller and turbine speed. Under

this condition, the converter will produce

torque multiplication

Coupling- The torque converter is behaving

in a manner similar to a simple fluid

coupling.

Overheating-Continuous high levels of slippage resulting in

damage to the seals that retain fluid inside the converter.

Stator clutch seizure- The inner and outer elements of the one

way stator clutch become permanently locked together,

thus preventing the stator from rotating during the coupling

phase.

Stator clutch breakage- A very abrupt application of power can cause shock loading of the stator clutch, resulting in

breakage.

Blade deformation and fragmentation- If subjected to abrupt

loading or excessive heating of the converter, pump and/or

turbine blades may be deformed.

Balloning-Operating a torque converter at very high

RPM may cause the shape of the converter's housing to be

physically distorted due to internal pressure.
