Its passage layout follows the lower valve-body mating surface used on Allison HD and B500 series transmissions, which is the detail that makes the position meaningful. Upper sealing layers occupy different positions within the hydraulic control stack, leaving this gasket specific to the lower channel. Pairing the transmission family with the channel position gives the Allison 29542920 two concrete checks technicians can use before reassembly.
