That is weird, so you do have some functional control with TMCC, but not all. Not sure why going thru MTH system allows reverse and Legacy does not.

I guess I would open it up and inspect what you have. I have seen K-Line engines either stripped of parts, or Cruise added. You could have a combination of issues. Part R2LC and Motor board, and Part railsounds. You can take the boards out and reseat. With proper pick tool, remove chips from RS board and reseat. That may resolve your Bell/Whistle issue. As far as Motor drive, try a new R2LC. Make sure antenna not grounded. After that need to look at the Motor drive board. If cruise, it could be a failure, or just missing serial data. If DCDR, it may think it is in conventional and goes full tilt. But that does not explain how you have other TMCC control. This one sound like it may need a more experience tech with the necessary parts to start swapping. G
