1. A transmission, comprising:
an input shaft configured to couple to a prime mover by a clutch;
a countershaft having a first plurality of gears mounted thereon;
a main shaft having a second plurality of gears mounted thereon;
an output shaft selectively providing a torque output to a driveline;
a shift actuator structured to selectively couple the input shaft to the main shaft by rotatably coupling at least one of the first plurality of gears to the countershaft and the second plurality of gears to the main shaft;
an integrated actuator housing, wherein the shift actuator is operationally coupled to the integrated actuator housing;
a clutch actuator housing, wherein a linear clutch actuator is positioned at least partially within the clutch actuator housing, and wherein the clutch actuator housing is one of coupled to the integrated actuator housing and comprising a portion of the integrated actuator housing;
wherein the integrated actuator housing further comprises a single air supply port, and wherein the linear clutch actuator and the shift actuator are powered through the single air supply port; and
a controller, wherein the controller comprises:
a clutch characterization circuit structured to interpret a clutch torque profile, the clutch torque profile providing a relation between a position of the clutch and a clutch torque value;
a clutch control circuit structured to command a position of the clutch actuator in response to a clutch torque reference value and the clutch torque profile; and
the clutch characterization circuit further structured to interpret a position of the clutch actuator and an indicated clutch torque, and to update the clutch torque profile in response to the position of the clutch actuator and the indicated clutch torque.
