A detent cable links the throttle linkage to the automatic transmission. This lets the transmission respond to throttle position, including the forced downshift when the pedal is pressed to the floor. Signs this cable may need replacing include a missing or delayed downshift at wide-open throttle, a frayed, kinked or binding cable, a broken end, or a cable that no longer holds its adjustment. If a worn detent cable is the cause, this part replaces it. Set the adjustment as directed in the vehicle's service information.
