Claim 9:
10. 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 and configured to charge a battery in an energy storage mode and be powered by the battery in an energy use mode;
an HVAC compressor selectively driven by the motor generator; and
a controller that operates the transmission in various modes based on operating conditions, wherein the various modes comprise (i) an engine off coasting (EOC) mode wherein the internal combustion engine is defueled and the motor generator is in the energy storage mode where rotational energy is routed from an output shaft of the transmission, through the countershaft and into the motor generator, and (ii) a sleep mode wherein the motor generator powers the HVAC compressor while the internal combustion engine is off.
