Abstract: A machine and method for cleaning an automotive automatic transmission by effecting the discharge of old used fluid from the transmission and the simultaneous replacement of this old fluid with new fluid on an exchange basis. The machine includes a set of primary hoses, a set of intermediate hoses, and a set of plural pairs of complementary adapter fittings which in combination adapt the machine for convenient service of a wide variety of automobiles and their transmissions. The primary hoses, intermediate hoses, and adapters are configured to fit together in a wide variety of different ways. This variability or flexibility of connection for the machine allows a very limited number of primary hoses, intermediate hoses, and adapters to interface the machine flexibly with a wide variety of different transmissions, and the different vehicles in which these transmissions are installed; all in accord with possibly differing preferences of particular service technicians who use the machine.
