(888) 312-8812 Login SignupThe Allison Fill Tube Seal fits into the transmission fill tube interface and forms a tight sealing boundary during operation. While the transmission is active, the seal stays compressed between adjoining surfaces as fluid moves internally. This interaction continues through repeated driving cycles without requiring adjustment. The seal is replaced during transmission repair or upgrade work when an existing seal no longer holds properly. It is shaped to match the original sealing position and restores proper containment behavior after service. Built as a direct service replacement, the Allison 29546229 supports continued transmission use following maintenance.
