• Q: How to replace the transmission pan on 2005 Buick Rendezvous?

  A: The replacement of an Oil Pan requires vehicle lifting and positioning a drain pan under the transaxle bottom Oil Pan. You need to remove the front and side bolts on the Oil Pan before loosening the rear bolts four turns. To prevent breaking the Oil Pan connection to the case use a rubber mallet or screwdriver for soft separation. Empty the entire fluid before taking out the remaining Oil Pan bolts and removing the Oil Pan together with its gasket. A thorough inspection should be conducted on the Oil Pan combined with its filter screen for identifying metal particles along with clutch facing material and rubber particles and engine coolant. All sources of contamination must be identified to initiate corrections. Replace the Oil Pan because any bending or distortion prevents proper installation. Attempting to manually straighten the pan should be avoided. Replace the bolt assembly with a new one if you find any inverted washer during the inspection. Check the Oil Pan for damage to the sealing surface as well as the dented or cracked bottom surface and examine the Oil Pan gasket for a bent or damaged seal core, damaged rubber seal surface or damaged gasket. Before mounting the Oil Pan check the magnet for damage and improper installation. Clean all sediment loose from the Oil Pan, gasket and magnet before installation. Dry down both the Oil Pan and case flanges thoroughly while eliminating all oil residue through cleaning with solvent. Allow both surfaces to air dry. Place the new Oil Pan gasket together with the Oil Pan before you install and tighten the Oil Pan bolts at 14 nm (10 ft. Lbs.). Lower the vehicle while putting the proper amount of dexron® iii transaxle fluid into place in the park position before starting the engine. Slow-speed engine operation should be maintained until you achieve the correct fluid level that avoids overfilling since this prevents foaming and loss of fluid while eliminating shift complaints and preserving transaxle integrity. The last step should involve examining the repair quality and verifying fluid leakages.
