What specific drivetrain mechanism, designed to manage gear selection automatically, is most associated with Spikes?

Answer

Automatic gear shift

The most significant contribution attributed to Richard B. Spikes concerning vehicle drivetrains was his development relating to the automatic gear shift. This invention aimed directly at removing the complex, manual coordination previously required by drivers—specifically linking the foot operation of the clutch pedal with the hand operation of the gear lever. By automating this process, Spikes sought to reduce the physical and cognitive demands on the operator, representing a crucial step toward the fully automated transmissions that would become standard much later.
