The transmission test rig supplies the transmission with conditioned oil and extracts the oil/air mixture from the sump. The sealing air supply and the vacuum inside the gear unit are controlled by the test rig. A multi-stage separator concept performs inline air separation from the oil as well as oil separation from the exhaust air. The test sequence including data recording and analysis are fully automated.
