OK. State Plane Coordinates are not the same as latitude and longitude. They are a separate coordinate system like UTM. I thought that it was just a different earth model optimized for the local area.
It is in this definition for srid 2204:
"+proj=lcc +lat_1=35.25 +lat_2=36.41666666666666 +lat_0=34.66666666666666 +lon_0=-86 +x_0=609601.2192024384 +y_0=30480.06096012192 +ellps=clrk66 +datum=NAD27 +to_meter=0.3048006096012192 +no_defs So Transform probably gives correct values. I had the wrong srid for my data.

On another note you have a typo - I think you meant to say 2204 is ... But
that is neither here nor there.  2204 is obviously not the right SRID for
that point.

I think your first guess 4267 is probably right.

Hope that helps,
