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

  A: First drain oil into the container beneath the transaxle Oil Pan while supporting the vehicle. Start by removing transaxle Oil Pan bolts at the front and sides before loosening the last bolt from the rear section. It is important to keep these mating Oil Pan and case surfaces undamaged to avoid leaking of fluid. A rubber mallet or screwdriver should be used to ease the Oil Pan from its position while the drain occurs. Strike all remaining transaxle bolts before removing the Oil Pan together with its gasket. Examination of both the Oil Pan and its filter should be done to check for metal particles and clutch facing material as well as rubber debris and engine coolant. The Oil Pan evaluation must determine and correct the origin of any discovered contamination sources. If you detect any bending of the Oil Pan flange then replace it before installation because attempts to straighten the part will be unsuccessful. Examine the Oil Pan bolts' washers after the bottom oil removal and substitute any inverted washers with new ones. Dry both the Oil Pan and case flanges before cleaning the case and Oil Pan surfaces with solvent while air drying them. Place the Oil Pan Gasket first followed by the Oil Pan until you install the Oil Pan bolts then secure them to 14 n.m (10 lb ft). Put the vehicle in the lowest position while filling the transaxle fluid to match its specified capacity. To begin start the engine when the gear selector is in park then maintain a slow idle by avoiding racing behavior while you check the fluid level and scan for any sign of fluid leakage.
