2009 Buick Lucerne Transmission Pan Parts Questions & Experts Answers

• Q: How to replace the transmission pan on 2009 Buick Lucerne?

  A: When replacing the Oil Pan begin by raising and supporting your vehicle while placing a drain pan under the transaxle Oil Pan. First remove bolts from front and side sections of the transaxle Oil Pan while you simultaneously loosen the last set of bolts located at the rear. When working with the Oil Pan to prevent leaks you must avoid harming the connecting surfaces with the case. A rubber mallet or screwdriver should be used to carefully open the Oil Pan to drain the fluid while maintaining it steady. Rearrange the transaxle bolts to remove the Oil Pan while it rests with its gasket . You need to check the Oil Pan and filter for signs of metal particles or clutch facing material and rubber particles and engine coolant. At the same time, find the origin of any contamination and fix it. Replace the Oil Pan flange even when it shows bending because attempts to fix it will result in failure. The bottom oil extraction procedure requires inspection of Oil Pan bolt washers for inversion to replace faulty ones. The Oil Pan and case flanges must be dry while remaining free of oil before cleaning both surfaces with solvent then drying them with compressed air. Mount the new Oil Pan gasket together with the Oil Pan before torquing the Oil Pan bolts to 14 nm (10 lb ft). Listen to the transmission operate and verify the fluid level of dextron(R) iii immediately after addition but avoid excess fluid because overfilling triggers vent tube foaming which can damage the transmission. Starting from park position select the gear while running the engine during slow idle with no racing while you check the fluid level and search for any leaks.
