I am scratching my head. For the second time trying to program my TMCC ALCo PA1's into the Legacy Control, I do not have all functions. In both instances the couplers will not open. The unit makes the uncoupling sound and you can hear the coupler try to open (buzz), but it does not open. When programing the dummy unit into the train, I choose 9, I had to MU it 'elephant style' in the Legacy Control to get the lighting to work correctly.
The first time my attempt failed, I reprogrammed the unit back to #1 and #2, then TR 9 per the operators manual with the TMCC command base and control. Oddly, the dummy unit was very stubborn about being reprogrammed back. But, I did get it. And all functions worked as advertised.
Am I missing something in the Legacy instruction manual?
