An A319 arrived with ECAM warning navigation predictive windshear detection fault; after engine shutdown. I found part number (P/north) #X weather transceiver (WX TR) installed. Aircraft had an engineering order to change windshear detection system; if hit again. I replaced the WX TR with P/north #Y. But the radar failed to displaya test pattern and failed to test. Called the line maintenance supervisor and got permission to reinstall P/north #X into the aircraft. Weather radar transceiver tested 'normal' per MM 34-41-00.
