2005 Buick LeSabre Parts Questions & Experts Answers

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

  A: Replacement of the Oil Pan needs the vehicle to be lifted and secured before directing fluid into a drain pan underneath the transaxle Oil Pan. Start by removing all transaxle Oil Pan bolts from their front and side positions and slightly loosen the bolts attached to the back. You should avoid damaging the Oil Pan surface against the case to stop oil from leaking. A touch of rubber mallet taps combined with a screwdriver working to extract the Oil Pan will release fluid into the drain. After removing all transaxle bolts you must uninstall the Oil Pan with its attached gasket from its position. Check the Oil Pan and filter for foreign substance types including metal fragments, clutch facing matter, rubber debris and engine coolant. Identify all sources of contamination and initiate their resolution. Replace the Oil Pan flange when bending occurs since attempts to straighten it must be avoided. The inspection of Oil Pan bolts should include a check for inverted washers which should be replaced together with new bolts when the Oil Pan bottom oil is removed. Proceed with cleaning the surfaces of the case along with the Oil Pan using solvent before air dry them both completely. After installing the new gasket for the Oil Pan it is time to place the Oil Pan into position. Finally, install the Oil Pan bolts while tightening them to reach 14 nm (10 ft. Lbs.). Lower the vehicle before filling the transaxle with dextron(R) iii using the correct amount of fluid to stop foaming and causing damage. After placing the gear selector to park start the engine at idle speed and check the fluid level while inspecting for any fluid leakage. The assembly process requires transjel(TM) j 36850 or equivalent fluid to preserve transaxle fluid characteristics.
