Technician A says that a torque converter is a type of fluid coupling.Technician B says that because a torque converter makes no direct mechanical connection between the engine and transmission,some loss of torque output results when the unit is not in lock-up mode.Who is correct?
A) Technician A only
B) Technician B only
C) Both A and B
D) Neither A nor B
Fluid Coupling
A hydrodynamic device used to transmit rotating mechanical power, relying on the transfer of energy through fluid motion.
Torque Converter
A type of fluid coupling used in automatic transmissions to allow the engine to spin somewhat independently of the transmission output, facilitating smooth vehicle acceleration.
Lock-up Mode
A function in automatic transmissions that directly connects the engine to the transmission to improve fuel efficiency and reduce slippage.

Final Answer :
C
Explanation :
Both statements are correct. A torque converter is indeed a type of fluid coupling that transfers rotating power from a prime mover, like an internal combustion engine, to a rotating driven load. It does this using a fluid hydrodynamic process, which means there is no direct mechanical connection between the engine and the transmission, leading to some loss of torque output when the unit is not in lock-up mode, as stated by Technician B.
