Lubrication system for transmission

A transmission assembly comprising:

• a transmission housing defining a transmission shaft extending at least partially through the transmission housing;
• a lubrication system disposed within the transmission housing, the lubrication system comprising:
• a lubrication tube in fluid communication with at least one of the plurality of gears;
• a plurality of oil conduits extending from and in fluid communication with the lubrication tube;
• a plurality of poppet valve assemblies, at least one of the plurality of poppet valve assemblies being disposed in each of the plurality of oil conduits;
• and
• a shift assembly translatable in a longitudinal direction relative the plurality of oil conduits;
• wherein the shift assembly is configured to engage each of the plurality of poppet valve assemblies to actuate each of the plurality of poppet valve assemblies between a closed position and an open position.

A method of lubricating a transmission system, the method comprising:

• scavenging, via a lubrication tube of a lubrication system disposed within the transmission system, oil from at least one of a plurality of gears;
• directing the scavenged oil from the lubrication tube to a plurality of oil conduits extending from the lubrication tube;
• and
• translating a shift assembly in a longitudinal direction such that the shift assembly actuates a plurality of poppet valve assemblies disposed in the plurality of oil conduits between a closed position and an open position;
• wherein the scavenged oil circumvents the plurality of poppet valve assemblies in the open position and the plurality of poppet valve assemblies form a seal with the plurality of oil conduits in the closed position.
