Electric axle parking mechanism with oil dam for stable oil level during uphill/downhill driving

A park mechanism in an electric drive unit may relocate an oil passage within an end housing and add a sensor dam. The sensor dam may separate a park mechanism cavity and a sensor cavity. The sensor dam may trap oil in the park mechanism cavity and prevent the sensor cavity from filling with the oil. The oil may trap the air above the oil in the sensor cavity, preventing the oil from reaching a height of a manual shaft. Thus, a seal of the manual shaft may be prevented from being submerged in the oil.
