Abstract
A system for alerting the operator of a vehicle to potentially damaging motoring of the engine before such motoring actually occurs so that corrective action can be taken. A speed sensor senses rotational speed of the counter/input shaft of a manual transmission and operates an indicator that presents the alert to the driver. The alert is given with the clutch disengaged as soon as the transmission is placed in a gear that causes the counter/input shaft to operate at a speed that will cause potentially damaging motoring of the engine. Because the alert is given before the clutch is re-engaged, an opportunity is given to prevent the potentially damaging motoring.
