Reprojecting NAD83 2011 to WGS84 for KML

Most of our ArcGIS projects are in a custom projection based on NAD83 2011. I cannot find a transformation for converting the data to EPSG4326 (WGS84) for export to kml files. I added the custom projection to the MyCoordSysDefs.fme file and it is reading the parameters. Anyone else working in the 2011 datum trying to export to KMLs? We are seeing a shift using the older NAD83 to WGS84 transformation, how do you work around that problem? Did you have to create a custom transformation?

It doesn't help that ESRI refers to the datum as GCS_NAD_1983_2011 and FME has it as NSRS2011. It appears not able to translate those two.

Have you tried setting the projection engine to ESRI rather than FME?

FME rocks! \m/

Sorry for the late response. I had but a shift still occurs. I have put this problem on my back burner for now but now it will rear it's ugly head again. I am certain it's in the NAD83 vs NAD83_2011 transformation parameters and the lack of transformations for going from NAD to WGS84. I see transformations for WGS to NAD83 but not the reverse and no option to check reverse. This is not the only software where we have this problem.
