I am not aware of any tuning systems that flash the Transmission Control Module, all just flash the Engine control unit AFAIK.
Ecutek appears to be able to adjust the traction control parameters somehow, it may be just adjusting whats sent from ECU to the VSC or TCM modules.
Maybe talk to the moteast or deliceous guys
Their was some changes to the ECU firmware after late 2014 ,it appears to be due to changes to dash firmware/hardware so its possible their were also corresponding changes to TCM firmware.
This may mean that even though the TCM module may be the same hardware as in earlier cars if you managed to flash later firmware to it it may no longer communicate/interact correctly with the other control modules in the car like the Stability control/DASH/ECU or some other control modules of the earlier car
This is likely why that TSB is only for 2015 cars
