In the context of Teleparallel Equivalent of General Relativity - TEGR - we have obtained, through the second kind gauge transformations, the most fundamental transformations, namely, the first kind ones. We show that considering the possibility of decomposing the components of the tetrad field as a trivial part plus some potential besides the usual translational and Lorentz potentials, there is also the possibility that the symmetry group of internal space be a generalization of the Poincar\'e group. Still in the analysis of transformations in the internal space, we saw that for the case in which the decomposition of the tetrad field components includes only a trivial part plus a translational potential, we recover just the translational group. Moreover, the internal space of gravity must be the very physical space - on a local scale - in such a way that the gauge symmetry group is the kinematical group of the spacetime itself. This group was obtained, and seems to generalize the Poincar\'e group.
