25098566 is a countershaft gear for Mack Multi transmissions, sold individually. Our parts manual lists it in the Mack T310M transmission main case components assembly at item 24, as Gear, Maindrive Countershaft.
Each gear range in a manual transmission pairs a countershaft gear with a matching gear on the mainshaft, so this gear is part of the power path for its range. Noise in only one range points to a worn or damaged gear pair there, and chipped or worn teeth are the most common cause. When a countershaft gear is changed, check the mating gear and the bearings too. Sold by Pro Gear and Transmission.
