The pion superfluidity phase transition at 
and 
planes are studied in the framework of Dyson-Schwinger equations. The rainbow truncation and Gaussian effective gluon propagator are employed to calculate pion condensate, 
, as a function of 
at finite T and 
. At 
MeV, the keeps zero when is less than a critical value 
. The at 
MeV agrees with the lattice QCD result. At the plane, the pion superfluid phase appears at low temperature and high isospin chemical potential region. At finite , varying with almost coincide for 
MeV. At plane, the pion superfluid phase appears at 
when MeV.
