In automatic transmissions, the device that replaces the clutch is known as the

• A. Hydraulic Pump
• B. Gearbox
• C. Torque Converter
• D. Bands

Answer: (C)

In automatic transmissions, the component that replaces the manual clutch is the torque converter. It sits between the engine and the transmission and uses fluid to transmit power from the engine to the transmission input shaft. This fluid coupling allows the engine to keep running while the car is stopped and enables smooth engagement and gear transitions without a mechanically connected clutch. It also offers torque multiplication at lower speeds, helping with initial rock-free starts.

The other options don’t fit this role. A hydraulic pump is part of the transmission’s hydraulic system that circulates transmission fluid to operate gears and clutches, but it doesn’t replace the clutch itself. The gearbox (or gearset) houses the gears that create different ratios. Bands are used in some automatics to hold certain drums during gear changes, not to replace the clutch.
