1. A transmission, comprising:
an input shaft configured to couple to a prime mover;
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 configured 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, wherein the shift actuator is mounted on an exterior wall of a housing, and wherein the countershaft and the main shaft are at least partially positioned within the housing;
a progressive actuator operationally coupled to an input clutch, wherein a progressive actuator position corresponds to a clutch position of the input clutch;
the input clutch configured to selectively decouple the prime mover from the input shaft; and
a clutch control logic configured to provide a lock-up time of the input clutch, the lock-up time comprising a time commencing with a clutch torque request time and ending with a clutch lock-up event, wherein during the lock-up time, the clutch control logic commands a position of the progressive actuator to maintain a clutch slip feedback value between a slip low threshold value and a slip high threshold value and the clutch lock-up event comprises a clutch slip value being lower than a clutch lock-up slip threshold value.
