【Replace Part Number】: 21396-P20-000, 21396 P20 000, 21396P20000.
【Function】: The function of the transmission breather cap is to regulate the pressure inside the transmission. When the internal pressure of the transmission increases, the breather cap will automatically open to discharge excess gas to prevent the internal pressure from being too high. This design can effectively prevent the oil seal from being damaged due to excessive pressure, and at the same time prevent dust, impurities and moisture from entering the transmission and causing malfunctions.
【Installation】: The installation of this transmission breather cap is extremely simple. You just need to find its position in the engine compartment and press it to complete the installation.
