Merchant Automotive 331304A Transfer Case Gasket

The Merchant Automotive 331304A Transfer Case Gasket for your GM 6.6L Duramax is a high-quality, replacement gasket that goes between the Allison rear housing adapter and the transfer case. This durable gasket is constructed from heavy-duty material and will not rip or tear like the less expensive gaskets. The 4WD transmission output adapter does not have an output shaft seal, so a gasket is required to prevent the transmission fluid from leaking. The factory gasket is not reusable, and this gasket should be replaced anytime the transfer case is removed from the truck.
