We consider the gluino-mediated SUSY contributions to B-0-(B-0) over bar mixing, B --> J/psiK(s) and B --> X(d)gamma in the mass insertion approximation. We find that the (LL) mixing parameter can be as large as \(delta(13)(d))(LL)\ less than or similar to 2 x 10(-1), but the (LR) mixing is strongly constrained by the B --> X(d)gamma branching ratio and we find \(delta(13)(d))(LR)\. The implications for the direct CP asymmetry in B --> X(d)gamma and the dilepton charge asymmetry (A(u)) are also discussed, where substantial deviations from the standard model (SM) predictions are possible.
