The transverse electron scattering response function of He-3 was recently studied by us in the quasielastic peak region for momentum transfers q between 500 and 700 MeV/c. Those results, obtained using the active nucleon Breit (ANB) frame, are here supplemented by calculations in the laboratory, Breit, and ANB frames using the two-fragment model discussed in our earlier work on the frame dependence of the longitudinal response function R-L (q,omega). We find relatively frame-independent results and good agreement with experiment especially for the lower momentum transfers. This agreement occurs when we neglect an omega-dependent piece of the one-body current relativistic correction. Inclusion of this term leads, however, to a rather pronounced frame dependence at q = 700 MeV/c. A discussion of this term is given here. This report also includes a correction to our previous ANB results for RT (q,omega).
