Systems and methods are provided for work fluid filtration in a transmission. 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.

Shift fork system and method. The shift fork system includes multiple fork guides that are removably coupled to a shift fork body. Each fork guide is configured to removably mate with a clutch assembly, including a hub, to enable the clutch assembly to be adjusted. Further, multiple attachment devices in the shift fork system are each be configured to releasably fix a position of one of the fork guides in relation to the clutch assembly.

Adjustable shift fork system for efficient assembly and disassembly of a clutch assembly

Methods and systems for an actuator cartridge. The actuator cartridge includes an actuation assembly that is rotationally coupled to an actuation motor and a sleeve. The sleeve includes a shift device groove that circumferentially extends around the sleeve and is configured to axially capture a shift device and gaps that extend from an axial side of the sleeve to the shift device groove.

A transmission shift fork comprising: an arch-shaped portion, where a pair of lobes are radially and inwardly projecting from an inner surface of the arch-shaped portion directing oil to a sleeve engagement region of a clutch.

Shift fork lubrication drip feature

Systems are provided for a gearset for a vehicle transmission. In one example, a system includes a shaft comprising one or more lubricant holes oriented radially within the shaft, and one or more gears positioned radially around a central axis of the shaft. The system further includes a ring positioned circumferentially around the shaft. The ring is shaped with a radially extending portion and an axially extending portion, wherein the radially extending portion may direct lubricant flow from the radially oriented lubricant holes toward the axially extending portion, and the axially extending portion directs lubricant flow from the lubricant holes in an axial direction towards the one or more gears. The axially extending portion and radially extending portion form a cut in the ring.

A planetary transmission system is disclosed. In an example, the system may include a planet gear, an outer bearing, and a planetary gear pin including an inner bore fluidly coupled to an outer bore, wherein the outer bore is narrower in diameter than the inner bore and a difference in diameter therebetween allows oil flow by gravity from the inner bore to the outer bore and reduces oil from flow from the inner bore to the outer bore, wherein oil exits the inner bore via a plurality of holes fluidly coupling the inner bore to the outer bearing without valves.

Planetary gear pin

Methods and systems are provided for a transmission housing of a vehicle. In one example, a system comprises a transmission housing comprising at least one cover configured to support a shift fork and press the shift fork toward a position sensor corresponding thereto, wherein the at least one cover is removable from an exterior of the transmission housing and comprises a spring to press against the shift fork.

Systems for transmission cover for supporting a shift fork

Methods and systems are provided for a transmission housing of a vehicle. In one example, a system comprises a transmission housing comprising at least one cover configured to support a shift fork, wherein the at least one cover is removable from an exterior of the transmission housing.
