1. Apparatus comprising:an engine controller responsive to the states of a remote engine speed control input signal and of a driveline disengage input signal for setting an engine throttle control output, and further responsive to the drive line disengage input for setting a value for an engine crank inhibit output signal; a transmission controller responsive to the states of an auto neutral enable switch and of a park brake for setting a value for an auto neutral output signal and further responsive to the position of the shift select lever for setting a value for shift select lever position output signal; and a logic network coupled for receiving the output signals from the transmission controller and the engine crank inhibit output signal from the engine controller as input signals and further coupled to apply a signal to the drive line disengage input of the engine controller, the logic network being responsive to the state of the auto neutral output signal for setting the value of the driveline disengage signal and being further responsive to the state of the shift position lever and the engine crank inhibit output signal for enabling a crank motor.
