REFL_TRANS LOCK LOSSES
Evan, Rana, Stefan

After we mostly fixed the CARM_ON_TR lock losses we ran into the REAFL_TRANS ones. There is definitely a loop instability on TR_REFL_TRANS. Be sped up this transition which at least once seemed to help. However we also randomly lost lock at other places, and never made it to low noise. We'll have another systematic approach tomorrow.
