Clutch with variable lubrication supply

A clutch system configured to transmit torque between an input shaft and an output shaft, the clutch system comprising:

• a synchronizing self-shifting (“SSS”) clutch comprising:
• an input portion disposed at an end of the input shaft;
• an output portion disposed at an end of the output shaft;
• and
• a sliding component that slides axially between the input and output portions to engage the clutch, wherein the input portion, the output portion, and the sliding component each comprises walls, and wherein the clutch comprises one or more chambers, each of the one or more chambers being enclosed by the walls of at least two of the input portion, the output portion, and the sliding component, wherein the one or more chambers include a second chamber enclosed by the walls of the output portion and the walls of the sliding component;
• a lubrication supply system comprising:
• one or more lubricant feeds for delivering a lubricant to the clutch;
• one or more lubricant drains for draining the lubricant from the clutch, and wherein the one or more lubricant drains includes a second lubricant drain that connects to the second chamber;
• wherein the one or more lubricant feeds comprises one or more respective valves, the one or more valves each being configurable between settings that vary an amount of the lubricant delivered to the clutch via the respective one of the one or more lubricant feeds.
