Which outcome results when a spool valve in a hydrostatic transmission system experiences significant wear?

💡 Explanation

Increased internal leakage and reduced pump efficiency occurs because wear degrades the spool valve's sealing via increased clearance between the spool and valve body, therefore fluid bypasses intended flow paths, rather than contributing to the actuator; other benefits are contradictory.
