A vehicle includes a brake pedal, engine, transmission, and controller. The transmission includes an input member and an input clutch responsive to position control signals. The controller has multiple control modules, each outputting a corresponding torque command. One module is a creep control module which outputs a calibrated creep torque. Intervention logic independently monitors the torque commands during a creep maneuver, with control actions executed when predetermined conditions are present. The torque command from the creep controller determines the position control signals of the input clutch during the creep maneuver, and creep torque is set to zero whenever the brake pedal is sufficiently applied. A transmission assembly includes the input member, input clutch, and controller. A method includes outputting torque commands from each control module, including the creep torque, monitoring the torque commands during the creep maneuver, and executing the control actions when the predetermined conditions are present.
