We present I = 1 spin-dependent total cross section predictions of a unitary, relativistic three-body model, described in earlier papers in this series, for the NN → NN and NN → NNπ coupled reactions. The spin-averaged NN → NNπ cross section is quite peripheral and is in good agreement with experiment from 500 to 2000 MeV. The elastic cross section is non-peripheral and does not agree with experiment. This is probably because of the neglect, so far, of short-range forces in the model. There are very large spin-dependent effects in both the elastic and NN → NNπ cross sections, even though this is a model without dibaryon resonances.
