  Q: How to properly service the transmission pan on Buick LaCrosse?

  A:

  A vehicle elevation and support system combined with a drain pan beneath the transaxle Oil Pan serves as the initial step before removing the transaxle Oil Pan bolts. Drain the transaxle Oil Pan by removing its bolts from front faces and side positions while loosening rear bolts. During the removal process avoid causing any damage to the Oil Pan mating surface with the transmission case so no oil leaks will develop. A rubber mallet should be used for gentle tapping of the Oil Pan while a screwdriver serves to pry it open so fluid can drain out. First remove all yet remaining transaxle bolts and uninstall both the Oil Pan with its gasket . Test the Oil Pan and filter for moderate contaminants consisting of metal fragments, clutch facing fragments, rubber particles and engine coolant then seek the root cause of all contamination to make repairs. Replace the Oil Pan because bent or distorted flanges cannot be repaired. Distortion should be checked on the Oil Pan flange separately after removing the Oil Pan. When the bottom oil pool has been drained check all Oil Pan bolt washers for incorrect orientation and perform a washers and bolts replacement. Dry all surfaces of the Oil Pan and case flanges while removing all oil film residues before cleaning both components with air dry. Drying the Oil Pan Gasket surfaces requires thorough cleaning until all past gasket material disappears. Place the Oil Pan Gasket on the pan before installing the pan followed by Oil Pan bolt torquing at 14 n.m (10 lb ft). After lowering the vehicle users must add fluid as indicated by transaxle capacity parameters. Select park on the gearbox before starting the engine to maintain slow engine operation without high speeds. Seek fluid adjustment for the system while checking for any leaking issues.
