A cooling assembly fluidly communicating with a vehicle cooling system includes a coolant tube and a mounting plate. The cooling assembly is configured for cooling a support bearing disposed in a dual clutch transmission. The coolant tube includes (i) an inlet end that receives a cooling medium, (ii) an outlet end that returns the cooling medium to the vehicle cooling system and (iii) a heat transfer portion incorporated between the inlet end and the outlet end. The mounting plate has a plate body including a bearing opposing surface and a transmission housing opposing surface. The bearing opposing surface contacts the support bearing. The heat transfer portion of the coolant tube is attached to the mounting plate such that cooling medium communicated through the coolant tube reduces temperature of the mounting plate and therefore the support bearing.
