  Q: How to Replace the Automatic Transmission Filter and Fluid on Buick LeSabre?

  A: Your first step to change automatic transmission fluid and filter should include raising then supporting the vehicle. A drain pan must be placed below the transaxle Oil Pan. You must handle Oil Pan bolts with care to protect sealing surfaces from damage because this would create future oil leakage. Begin by extracting the Oil Pan bolts from both sides and the front portion then carefully loosen the rear bolts only to a four-turn level. A rubber mallet or light prying motion on the Oil Pan enables drainage of fluid while you check the fluid colors. Finish the operation by detaching the Oil Pan with its gasket after unbolted remaining Oil Pan hardware. Check the oil filter seal condition with a long screwdriver before carefully removing the oil filter neck from its seal. When necessary you should detach the seal with a j 23129 (Universal Seal Remover) together with a j 6125-1b (Slide Hammer). When installing the seal you should apply j 36850 (Transmission Assembly Lubricant) or petroleum jelly to the surface of a new seal beforehand. The installation process requires putting in a new filter into the case with the understanding that Oil Pan gaskets have a single use unless the sealing surface shows damage. Place the Oil Pan and gasket together before securing all the Oil Pan bolts to 14 nm (125 inch lbs.). Proceed with vehicle lowerment and measure the transaxle fluid level before checking for possible fluid leakage by inspecting transmission fluid and Oil Pan Gasket.
