Answer 1

Answer #1

Sno	Torque convertor	Hydraulic Coupling
1	Torque convertor transmits torque from engine to automatic transmission through fluid	Hydraulic Coupling transmit torque from engine to gear box through fluid
2	Torque Converter consists of pump impeller, turbine and rotor.	Hydraulic Coupling consists of pump impeller and turbine
3	Torque Converter serves purpose of automatic gearbox	Hydraulic Coupling serves the purpose of automatic clutch and hence does not require clutch pedal.
4	Torque Converter blades are inclined	Hydraulic Coupling blades are merely fins
5	Torque convertor multiplies the torque about 2:1 to 3:1	The Hydraulic Coupling transmits the same torque as provided by engine
6	Torque Converter is not sufficient at higher speed but it is efficient under loads.	Hydraulic Coupling is sufficient at highway speeds
