A powertrain component mount includes a housing, a main rubber element, a hydraulic body, a membrane and a valve. The main rubber element has an outer armature, an inner armature and an isolating element coupled to the armatures, the isolating element being formed of a material that is more flexible than the outer armature and the inner armature, wherein the main rubber element defines at least part of a fluid flow path. The hydraulic body supports the outer armature of the main rubber element, defines part of the fluid flow path, a fluid chamber, and part of a control chamber communicated with the fluid flow path. The hydraulic body has a port open to the control chamber. The membrane defines part of the control chamber and the valve has a valve head movable between a first position closing the port and a second position spaced from the port.
