• Q: How to Replace the Automatic Transmission Filter and Fluid on 2005 Chevrolet Astro?

  A: A vehicle lift and drain pan positioned under the transmission Oil Pan should be the first steps before changing automatic transmission fluid and filter. You must remove the Oil Pan Drain Plug if it exists but you can lower the pan by loosening bracket bolts around the range selector cable without unhooking the lever or bracket. Drain fluid by removing front and side Oil Pan bolts while keeping the rear bolts loose to 4 turns before using a rubber mallet for light tapping of the pan. To remove the filter you should first eliminate all remaining bolts before taking off the Oil Pan alongside its gasket which can be removed by firmly twisting the filter. Pull away the filter seal through the use of pliers if necessary for removal before disposing of it. Study the fluid appearance and filter contents to identify clues of clutch debris and verify that it does not contain bronze shavings as a sign of bushing deterioration, steel pieces or other contaminants. The transmission case and Oil Pan Gasket surfaces need cleaning with solvent while removing any remaining gasket material. Automatic transmission fluid should be applied to the new filter seal before you install it into the transmission case using a suitable size socket for installation. A new filter installation should be followed by putting in the Oil Pan with a new gasket and tightening all transmission case bolts to 11 nm at 97 inch lbs. In a specific alternating pattern. Put back the range selector cable bracket then bolt it down to 25 nm (18 ft. Lbs.). Use the gm p/n 12346004 sealant on the Oil Pan Drain Plug threads (if present) before installing it tightly to 18 nm (13 ft. Lbs.). Fill the transmission with dexron iii fluid to the correct level while checking the initial cold fluid mark and examine the Oil Pan Gasket for leakage.
