Abstract: A transmission is subject to thermal management to prevent damage or failure due to overheating. Sensors can be employed to capture characteristics of a transmission, such as fluid temperature or pressure. Further, a predictive model can be invoked to predict characteristics based on current and future conditions. Characteristics can be compared with a threshold for intervention. A thermal mitigation strategy can be generated and initiated when characteristics satisfy the threshold. The thermal mitigation strategy can specify various actions to dissipate heat, including altering shift control logic and triggering mechanical devices that can increase airflow, reduce air temperature, or both surrounding the transmission.

Abstract: A manifold for distributing lubricant in a transmission includes an inlet supply nozzle, a first body portion and a second body portion. The inlet supply nozzle receives transmission lubricant. The first body portion is in fluid communication with the supply nozzle and defines a first channel having a first open side along the first channel.

The first and second body portions connect to form an assembled body in an assembled position such that the first and second channels collectively define a main tubular passage. A plurality of outlet ports can extend from the assembled body for dispersing lubricant from the main tubular passage across traction components of the transmission.
