Abstract
A torque converter lock-up clutch (26) control is provided which is adaptive to sensed torque demand across the torque converter (20) of a vehicular automated transmission system (12). Torque demand is, in one embodiment, sensed as a function of torque converter slip rate ((ES-IS)/(ES)), and torque converter lock-up is delayed upon sensed positive (ZNV ((ES-IS)/(ES)) torque converter slip rate.
