Question

Quizplus · Accepted Answer

Both Technician A and Technician B are correct. The lockup piston clutch in an automatic transmission serves to improve fuel economy by directly connecting the engine to the transmission at certain speeds, eliminating the slippage and inefficiency of the torque converter. Additionally, it is designed with a damper assembly to smoothly transmit driving torque and absorb driveline shock, enhancing the driving experience and protecting the drivetrain components.
