A combustor for a turbine including: a combustor liner, a first flow sleeve surrounding the combustor liner to define a first flow annulus, the first flow sleeve having cooling holes for directing compressor discharge air as cooling air into the first flow annulus, a transition piece body connected to the combustor liner to carry hot combustion gases to the turbine; a second flow sleeve surrounding the transition piece body, the second flow sleeve having cooling holes for directing compressor discharge air as cooling air into a second flow annulus between the second flow sleeve and the transition piece body; at least one dilution hole in the combustor liner for flowing compressor air into a combustion chamber defined by the combustor liner; and a bushing seated in at least one of the cooling or dilution holes and secured with respect thereto for defining a flow passage for compressor discharge air through the hole.
