Your locomotive was made prior to the modular boards, so there's nothing to re-seat.
Before we do anything else, do a "restore" on your locomotive using the procedure on Page 12 of your manual. Make sure you are using the "4" code.
If that doesn't fix things, it sounds like the RailSounds in the tender is not seeing the serial line in TMCC mode. To verify this, run your loco in TMCC mode. Does the sound system still respond to whistle and bell commands from your transformer while in TMCC mode?
Also, does the back-up light and rear coupler work in TMCC mode?
Lastly, does the tether between the locomotive and tender have all six pins intact?

I have attempted to do the "restore" process several times with this loco and then I did it with my other (newer) locomotive just to see what the result should be. The GS-4 does not respond to the "restore" procedure laid out on page 12.
Running the loco in TMCC environment the railsounds whistle responds to the transformer but not the CAB-1 remote and there is no response from bell, CrewTalk, or TowerCom.
After completing the "restore" procedure I have gotten CAB-1 remote to control: throttle, brakes, boost, direction (with tender lights). headlight on/off. and the rear coupler. So I believe my issue is in the RailSounds module within the tender. The tether has all six pins (with one pin permanently in the loco plug). Is there a simple way to test the tether with a voltmeter?
