The volume of transmission fluid needed to apply the friction elements are continuously monitored and learned for adaptive controls. As the clutch friction material wears, the volume of fluid needed to apply the clutch increases. Certain transmission mechanical problems can cause near-zero learned volume resulting in setting a DTC. The DTC will usually set with other DTCs which indicates an internal transmission problem.
