Abstract: Methods and apparatuses are provided for servicing a system having a used fluid, an inlet and an outlet. An exemplary apparatus comprises a first hose capable of being connected to the inlet, a second hose capable of being connected to the outlet, a first fluid tank including a first new fluid, a second fluid tank including a second new fluid, a pump and a selector. The selector selects one of the tanks and the pump pumps the new fluid from the selected tank into the system through the first hose and the inlet, and the second hose receives the used fluid via the outlet. For example, the first and second fluid tanks may communicate with the pump via first and second valves, respectively, and the selector may open the first valve and close the second valve, so that the pump pumps the first new fluid from the first fluid tank.

Abstract: An apparatus and method for determining direction of flow in a fluid or pneumatic system. The apparatus comprises first and second conduits having clear portions, the first and second conduits being capable of determining fluid flow direction in the system by observing fluid through their clear portions. The apparatus further comprises a valve assembly connecting the first conduit to the second conduit, the valve assembly including a shut-off valve. The valve assembly can comprise a release valve for releasing fluid from the valve assembly, and a release mechanism for opening the release valve. The system may include a transmission system and a fluid circuit with a first port and a second port, a transmission service system being connected to the first port and the second port of the fluid circuit according to the direction of fluid flow determined by the apparatus.

Abstract: Method and apparatus for servicing a vehicle's transmission cooling system, where the apparatus includes a source valve with inlet and outlet ports, a pump with inlet and outlet ports, and a return valve with inlet and outlet ports. The pump inlet is connected to the source valve outlet. The pump pumps fluid from the source valve inlet through the source valve outlet and the pump inlet to the pump outlet for servicing the transmission cooling system. The fluid returns from the return valve inlet to the return valve outlet and the pump then re-pumps the fluid into the transmission cooling system. The service apparatus may also include a fluid source and a filter interposed between the fluid source and the source valve, where the fluid returns to the fluid source prior to re-pumping the fluid. The service apparatus may also include a flowmeter interposed between the return valve and the fluid source and a filter interposed between the return valve and the flowmeter.
