Differential with lubricant control

A vehicle comprising:

• a differential;
• a housing having a primary chamber containing the differential and fluid;
• a secondary chamber adjacent the primary chamber and having an inlet in fluid communication with a first region of the primary chamber and an outlet in selective direct fluid communication with a second region of the primary chamber;
• and
• a valve configured to selectively permit fluid to flow from the outlet, through the valve, and directly into the second region in response to a temperature of the fluid exceeding a threshold.

A method comprising:

• operating a ring gear of a differential within a primary chamber of a housing to cause lubricant to enter a secondary chamber of the housing;
• storing the lubricant in the secondary chamber while a temperature of the lubricant is less than a threshold;
• and
• releasing the lubricant from the secondary chamber, through a valve and directly to the primary chamber in response to the temperature exceeding the threshold.
