Automotive transmission with heat exchanger bypass cartridge

A transmission that can be assembled into a transmission without a cooler and a transmission having an oil cooler includes a housing and a lubrication system. An oil passage system includes an oil passage having an oil outlet opening extending from the housing and an oil inlet opening extending into the housing. A bypass flow passage is disposed in the housing in communication with the oil outletopening and the oil inlet opening. In a cooler-free configuration, a pair of plugs are inserted into the oil outlet opening and the oil inlet opening, respectively, to close the oil outlet opening andthe oil inlet opening such that oil flows from the oil outlet opening to the oil inlet opening through the bypass flow passage. In a transmission configuration having an oil cooler, an external oil cooler is connected to the oil outlet opening and the oil inlet opening. 一种能够被组装为无冷却器式变速器和具有油冷却器的变速器的变速器，包括壳体和润滑系统。油通道系统包括油通道，所述油通道具有从所述壳体延伸出的油出口开口和延伸到所述壳体中的油入口开口。旁通流动通道与所述油出口开口和所述油入口开口连通地设置在所述壳体中。在无冷却器配置中，一对插塞被相应地插入所述油出口开口和所述油
