The systems include a work fluid filter system for a transmission comprising: a canister filter arranged on an exterior of a transmission housing, the canister filter fluidically coupled to a suction side of a pump and a reservoir, wherein the canister filter receives work fluid directly from the reservoir via a pickup tube without a filter that is more coarse than the canister filter.
