1. 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; and
wherein the transmission housing comprises a bell housing located radially about a shaft of the transmission with the shaft positioned along a central axis of the bell housing, wherein the pump is separately housed and externally fastened to an opening of the bell housing, and wherein the pump and the canister filter are radially offset from the shaft, such that a first distance between the pump and the shaft is approximately equal to a second distance between the canister filter and the shaft.
