An automatic transmission fluid change apparatus includes a drain pan and associated holding tank for collecting and retaining used fluid recovered from an automatic transmission. A new fluid reservoir is provided within the apparatus to contain the quantity of new fluid required for a complete change of fluid in the transmission. To accomplish a complete change of fluid in the automatic transmission, the transmission pan and filter are removed and new fluid is pumped from the new fluid reservoir to the transmission orifice to which the outlet tube of the filter is typically coupled. The vehicle engine is simultaneously run at idle speed to circulate the new fluid throughout the transmission, thereby forcing all used fluid out of the transmission for collection and storage in the holding tank.
