The transmissions described rely on which control method to operate clutches?

• A. Electronically
• B. Hydraulically
• C. Mechanically
• D. Sequentially

Answer: (A)

Electronic control is used to operate the clutches. In modern transmissions, the clutch packs are actuated by hydraulic pressure, but that pressure is controlled by electronic signals from the transmission control module or ECU through solenoids and valve bodies. This electronic control allows precise timing, smooth shifting, and integration with engine and vehicle systems. The other ideas describe medium or sequence rather than how the clutches are commanded: mechanically would imply direct manual linkage, which isn’t how these transmissions engage clutches; hydraulically refers to the fluid-based actuation itself, but the crucial point is that the actuation is governed by electronic control; sequential describes the order of gear changes, not the control method.
