A system for providing total fluid exchange for an automatic transmission which interconnects with the transmission's opened cooling circuit to deliver new, fresh fluid to the transmission while simultaneously extracting the spent, used fluid. The system provides a means of quick and random interconnection to an opened cooling circuit and means of identifying and aligning direction of flow in such cooling circuit. The system can accurately calibrate and regulate the rate that fresh fluid will flow into the transmission to be the same as that at which the used fluid is extracted, both of which are regulated to flow at the same rate that fluid normally circulates at in the cooling circuit when it is closed under similar operating conditions. Quick coupling devices are used for ease and speed of interconnection of the system into operative position, for quick removal of the system and for reconnection of the opened cooling circuit for ease of repeat, periodic servicing by the system as a regular maintenance procedure.
