The disclosure provides a transmission and a transfer case with torque sensing. A powertrain incorporates a link shaft between the transmission output shaft and downstream components in order to facilitate use of a torque sensor. The link shaft includes an inner section splined to the output shaft and an outer section treated to produce a magnetic field that varies based on transmitted torque. The inner section and outer section are separated by a circumferential gap that directs the torque past the treated surface. Use of the link shaft eliminates the need to directly treat the transmission output shaft. Separation of the spline and the treated surface radially reduces the axial length required for torque sensing and allows commonality among variants with and without torque sensors and between two wheel drive and four wheel drive variants. 本公开提供种具有扭矩传感的变速器和分动器。为了方便扭矩传感器的使用，动力传动系统在变速器输出轴和下游部件之间包含连接轴。所述连接轴包括内部和外部，所述内部花键连接到输出轴，所述外部处理成产生基于所传递的扭矩而变化的磁场。所述内部和所述外部由周向间隙隔开以引导扭矩通过所处理的表面。使用所述连接轴消除了直接处理变速器输出轴的需要。将所述花键与所
