Abstract
A machine for replacing used transmission or power steering fluid in a vehicle with new transmission or power steering fluid includes a frame having a housing. The machine includes a pair of service hoses that extend from the machine and connect to the vehicle for placing the machine in the fluid flow. New, used, and axillary fluid tanks are provided. A pump and a manifold are associated with two of the tanks. The pumps provide for the selective withdraw or insertion of fluid into or out of the tanks. A display on the housing presents an operator of the machine with various tasks or options the machine can perform. A processor controls activation of the pumps and other electrical components based on inputs received by the display. Scales are provided under one or more of the tanks for determining the amount of fluid going into and out of the tanks during the exchange process.
