2008 Buick Lucerne Parts Questions & Experts Answers

• Q: How to replace the transmission pan on 2008 Buick Lucerne?

  A: You must start by lifting your vehicle then supporting its weight with some means before placing a drain pan underneath the transaxle Oil Pan. From the front and sides of the transaxle remove the pan bolts. Also loosen the rear bolt. Be careful while unfastening the Oil Pan interface from the case to ensure no leakages occur. Apply a screwdriver or rubber mallet to slowly detach the Oil Pan then drain out the fluid contents. You must uninstall all transaxle bolts then remove the Oil Pan together with its gasket. Examine the Oil Pan components alongside the filter for traces of metal particles and clutch facing material, rubber particles and engine coolant. Locate and fix any potential contaminants. Any bending or distortion in the Oil Pan flange warrants a new flange replacement since attempts at straightening it are ineffective. The process to remove bottom oil necessitates replacing any inverted washers found on the Oil Pan bolts as a part of inspection. Wipe all surfaces of the Oil Pan and case flanges to evaporate all oil residue before using solvent to clean their gasket areas. Allow the surfaces to dry through air circulation. First apply the new Oil Pan Gasket followed by the Oil Pan itself then mount the Oil Pan bolts while tightening each one to 14 n.m (10 lb ft). The vehicle should be lowered down while adding dextron(R) iii fluid but the level should not exceed capacity to prevent foaming and equipment destruction. Per the instructions start the engine when placing the gear selector to park then adjust the fluid level while running the engine at idle speed without racing and check for any signs of leakage.
