OK - Good News - the oscillation is gone - the glide slope is greatly improved - indeed much more flyable and enjoyable.
Bad News - FLC is now busted, it will get to the point where the vertical speed begins to slow when approaching target altitude and then disengage with an automatic alt hold coming on - usually about 1,500ft short of target. VS mode works fine still. Also unless I’m missing something it seems as if the master caution/warning alert resets don’t do a thing anymore so it’s a constant dong dong warning until engine start? Please someone let me know how to get around this if possible - super annoying!!
Altogether though its much improved.
