We study supergravity solutions corresponding to fivebranes wrapped on a three-sphere inside a G(2) holonomy manifold. By changing a parameter the solutions interpolate between a G(2) manifold X-i congruent to S-3 x R-4 with flux on a three-sphere and a distinct G(2) manifold X-j congruent to S-3 x R-4 with branes on another three-sphere. Therefore, these realise a G(2) geometric transition purely in the supergravity context. We can add D2 brane charge by applying a simple transformation to the initial solution and we obtain one-parameter deformations of warped G(2) holonomy backgrounds. These solutions suggest a connection between the N = 1 Chern-Simons theory on the fivebranes and the field theory dual to D2 branes and fractional NS5 branes, transverse to the G(2) manifold S-3 x R-4.
