The Fuller Transmission Breather allows internal pressure within the transmission housing to equalize during operation. As temperature changes cause expansion and contraction of air inside the unit, the breather provides a path for pressure to escape. This helps prevent pressure buildup that could affect seals or internal components. Its compact design fits into the transmission housing at designated breather ports. The Fuller 4304602 functions as the venting component for transmission pressure regulation.
