Question 1

How to replace the transmission pan on Buick Lucerne?

Accepted Answer

After supporting the vehicle at a proper height you should place a drain pan under the transaxle Oil Pan. Start by unfastening the bolts located on the front and sides of the transaxle Oil Pan but keep the rear bolts slightly loose. Use a rubber mallet along with a screwdriver to avoid damaging the Oil Pan to case mating surfaces when separating them. The Oil Pan needs to drain all fluid before you can remove the other bolts and the Oil Pan itself. Inspection of both the Oil Pan and filter begins after removing the Oil Pan gasket where engine coolant, rubber particles, clutch facing material, steel shavings, and other foreign items should be evaluated to establish the potential source of any contamination. Always replace the distorted or bent Oil Pan flange since bent portions cannot be rectified safely. The removal of bottom oil requires an inspection of Oil Pan bolts washers for inversion which should be replaced at the same time as the bolts. First dry the Oil Pan and case flanges before cleaning each surface with solvent until ready for air drying. Begin by installing both the new Oil Pan gasket along with the Oil Pan with careful bolt application at 14 nm (10 ft. Lbs.). Pour dextron(r) iii fluid in the transaxle but do not surpass the maximum level to avoid foam formation and equipment destruction. Start the engine while keeping the gear selector in park then operate at slow idle conditions before racing the engine. The fluid level needs adjustment while looking for any evidence of leakage.

Question 2

How to replace the transmission pan on Buick Regal?

Accepted Answer

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.
