An improved throttle control assembly (36) in combination with an electronic controller (48) for controlling shifting in an automated mechanical transmission system (10) having a non-electronically controlled engine (14) is provided. The combination of the throttle control assembly and the control allows the non-electronically controlled engine to be subject to throttle blip as well as throttle dip operations while preventing continuing unsafe conditions as a result of single point failures.

Throttle control for automated mechanical transmission

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.
