1. A transmission control system for a transmission selectively coupled to an engine crankshaft of an internal combustion engine arranged on a vehicle, the transmission control system comprising:
a motor generator selectively coupled to a countershaft of the transmission;
an HVAC compressor selectively driven by the motor generator; and
a controller that operates the transmission in a first engine off coasting (EOC) operating mode that includes defueling the internal combustion engine while the vehicle is moving based on vehicle operating conditions and routes rotational energy from an output shaft of the transmission, through the countershaft and into the motor generator.
