TRANSMISSION MOUNTED ELECTRICAL CHARGING SYSTEM WITH ENGINE OFF COASTING AND DUAL MODE HVAC

A transmission system selectively coupled to an engine crankshaft of an internal combustion engine arranged on a vehicle includes a transmission, a motor generator an HVAC compressor and a controller. The transmission has an input shaft, a mainshaft, an output shaft and a countershaft offset from the input shaft. The countershaft is drivably connected to the first input shaft and a mainshaft. The motor generator is selectively couple to the countershaft. The HVAC compressor is selectively driven by the motor generator. The controller operates the transmission system in various modes based on operating conditions.
