  We complete the analysis of transport phenomena in p-wave superfluids within
gauge/gravity duality, using the SU(2) Einstein-Yang-Mills model with
backreaction. In particular, we analyze the fluctuation modes of helicity zero
in addition to the helicity one and two modes studied earlier. We compute a
further transport coefficient, associated to the first normal stress
difference, not previously considered in the holographic context. In the
unbroken phase this is related to a minimally coupled scalar on the gravity
side. Moreover we find transport phenomena related to the thermoelectric and
piezoelectric effects, in particular in the direction of the condensate, as
well as the flexoelectric effect. These are similar to phenomena observed in
condensed matter systems.
