To operate the manual pump shift, both automatic transmission and pump shift control must be in which gear state?

• A. Drive
• B. Neutral
• C. Park
• D. Reverse

Answer: (B)

Neutral is required because the pump shift is designed to operate with the engine decoupled from the drivetrain. When the transmission is in neutral, the engine can drive the pump without loading the drive wheels, allowing safe and uninterrupted engagement of the manual pump gear. If you left the transmission in Drive or Reverse, the engine’s torque would be trying to move the vehicle and load the pump, which can cause gear clash, stalling, or unintended movement. Park locks the output and prevents rotation, so it isn’t suitable for operating the pump shift either. In short, Neutral isolates the drivetrain so the pump can be shifted and run safely.
