• Q: How to replace the transmission pan on 2001 Buick Century?

  A: Begin by first supporting and raising the vehicle before setting a drain pan under the transaxle bottom Oil Pan. Begin the process by unscrewing all front and side Oil Pan bolts then turn the rear bolts four times before carefully loosening the mating surfaces to avoid oil leakage. A rubber mallet or screwdriver can used for gently prying out the Oil Pan after which the liquid drains until all Oil Pan bolts and the Oil Pan with the Oil Pan Gasket can be removed. The bottom Oil Pan and filter screen require inspection for contaminants including metal fragments, clutch facing debris, rubber shavings and engine coolant damage with identification of their cause for correction if found. The Oil Pan flange should undergo inspection for warping and the technician must replace damage to any flange which cannot be made straight with normal procedures. Replace the bottom Oil Pan bolts only after inspecting their washers for inverted orientation because this requires new bolt and washer assemblies. Before proceeding dry and clean the case and Oil Pan Gasket surfaces using solvent then allow them to air dry. Complete removal of old gasket material is essential before adding the new Oil Pan Gasket alongside the Oil Pan itself. Position the Oil Pan bolts before torquing them to 14 nm (10 ft. Lbs.) then lower the vehicle and dissolve the transaxle with the recommended dexron iii fluid amount. Set the gear selector to park then begin the engine at low speed with no racing. Check and adjust fluid levels while inspecting the work quality to determine any transmission fluid leaks.
