Allison's current transmissions are __________ controlled.

Allison's current transmissions are __________ controlled.

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

Answer: (B)

Allison current transmissions are electronically controlled. The shifting decisions, timing, and how hydraulic pressure is applied to the shift valves are governed by an electronic control module. This electronic logic coordinates with sensors to optimize gear selection, boost efficiency, and enable diagnostics, while the hydraulic system actually moves the valves and operates the clutch packs. So, even though hydraulic action handles the physical shifting, the control comes from electronics, making electronically controlled the accurate description.
