Abstract: An improved system for changing the fluid of vehicular automatic transmissions and the like, which has the capability to provide a complete fluid exchange faster and with less usage of fresh fluid in a manner that is easier to operate. This is accomplished by the system's unique capability to extract used fluid and replace it with fresh fluid at a faster, balanced rate than before possible in prior art. This is accomplished by decreasing or removing restriction from the exhausting of the used fluid and introducing fresh fluid at more than one locus. The unique, novel capability of the invention to use a dual use pan access tube to combine a static change with a dynamic change, and to introduce fresh fluid into the transmission from two different loci instead of one as in all prior art, allows the fluid exchange to be completed in a shorter time with less use of fluid.

Abstract: A spent transmission fluid is drained from a transmission and replaced with new fluid. The transmission's converter forces the spent fluid into a spent fluid container, while air displaced by the entering spent fluid is forced into a second container holding a new replacement fluid. The second container is thereby pressurized and the new fluid is thus forced through an interconnecting conduit line into the dipstick tube so as to replace the spent fluid flowing out. The spent fluid leaving the transmission causes suction to appear at the dipstick tube which sucks the new fluid into the transmission. To assure that this suction is maintained, the dipstick tube is sealed so that the system is closed.
