comment Transcendental equation inside another equation when 3D plotting
Your errors are coming from ContourPlot3D attempting to evaluate g with symbolic arguments. You need to define g so that it only takes numeric arguments, like g[x_?NumericQ, t_?NumericQ] := blah. The same goes for k obviously.

comment Custom TransformationFunction in Graphics? GeometricTransformation::nonaffine error
@bills, I think your latest edit sums up the situation nicely. I see no reason to replace it with one of mine that would just say the same thing :-)

@0x4A4D, apparently so did WRI when they wrote the manual...

comment Custom TransformationFunction in Graphics? GeometricTransformation::nonaffine error
Yes, it effectively sets the bottom row of the matrix to {0,0,1} to make the transformation affine. It would be better if the message explained that, so you know that what you get out is not what you asked for.

comment Custom TransformationFunction in Graphics? GeometricTransformation::nonaffine error
@bills, I see what you mean, but Suzan is using the first form: GeometricTransformation[g, tfun] and it isn't clear that tfun must be affine.
