Ball Screw Block

A component of a ball screw system that moves linearly along the screw, converting rotary motion into precise linear motion.

Shift Finger Transversely

Refers to the movement or positioning of a shift finger (a component in gear selection mechanisms) across a lateral axis to engage different gears.

Inertia Brake

On an automated standard transmission, this solenoid actuated brake helps stop the countershafts on initial engagements when the clutch is either out of adjustment or defective.
