Which technician's statement is correct regarding an automated transmission?

• A. Technician A only
• B. Both A and B
• C. Neither A nor B
• D. Technician B only

Answer: (A)

Automated transmissions rely on a hydraulic system that is precisely controlled by an electronic control module. The pump creates hydraulic pressure, the valve body directs that pressure to various clutch packs and bands, and the transmission control module (TCM) or engine control module (PCM) commands solenoids to adjust pressure and shift timing based on inputs like vehicle speed, throttle position, and engine RPM. A correct statement will accurately describe this electronic-hydraulic control loop and how it determines when and how firmly to apply gear sets.

Without the exact statements from Technician A and Technician B, I can’t conclude which one is correct. If you share what each technician said, I can pinpoint which statement aligns with how automated transmissions operate and explain why it’s the best.
