  Q: How to service and repair the transmission pan on Buick LeSabre?

  A: A vehicle lift will service and repair the fluid pan by using a drain pan for the transaxle Oil Pan. Put the drain pan beneath the transaxle Oil Pan. During Oil Pan bolt removal avoid damaging either sealing surface since this will result in an oil leak. Unfasten the Oil Pan bolts on the Oil Pan front section along with the sides and next gently rotate the rear Oil Pan bolts by 4 turns. Lightly strike the Oil Pan using a rubber mallet to drain fluid while inspecting the fluid color. When the oil drain processing ends remove all remaining Oil Pan bolts before uninstalling the Oil Pan along with its gasket. The Oil Pan gasket must be installed with a new gasket where sealing ribs become damaged. Place the Oil Pan bolts on their matching holes before tightening them to 14 nm (10 ft. Lbs.). Before filling the transaxle use dexron(R) iii fluid or equivalent to reach the correct fluid mark. Perform the initial fluid fill on the cold level without exceeding capacity and inspect for any leaks throughout the Oil Pan gasket.

  Q: How to replace the transmission pan on Buick LaCrosse?

  A: You should replace the Oil Pan using transjel j 36850 or equal assembly lube instead of using grease because grease can modify transaxle fluid behavior which causes shifting problems and filter blockages. Position the car on a lift platform while shifting the drain container under the Oil Pan of the transaxle. The first front and side bolts of the transaxle Oil Pan need removal followed by rear bolt loosening before gently tapping or prying the Oil Pan free to safeguard mating surfaces. Allow full drain of fluid before you take out the additional Oil Pan bolts and the Oil Pan from its position. Next remove the Oil Pan Gasket . You should carefully examine the Oil Pan together with filter for all types of contaminants like metals or clutch facing material or rubber substances or engine coolant to determine their source before resolving the issue. Distortion of the Oil Pan flange requires replacing the component because attempts at straightening could prove unsuccessful. The inspection of Oil Pan bolts washers should take place when bottom oil removal is performed. Replace inverted washers while changing the bolts. A clean dry Oil Pan and case flange should be used to avoid leakage by cleaning them with solvent followed by natural air drying. The new Oil Pan Gasket combined with the Oil Pan needs to be installed before tightening the Oil Pan bolts to 14 nm (10 ft. Lbs.). The transaxle of the vehicle must be lower while technicians fill it with dextron iii fluid while keeping the gear selector in the park position. After starting the engine at slow speed maintain an idle without race conditions you should inspect for leaks while adjusting the fluid level.

  Q: How to Ensure Proper Installation of the Transmission Pan on Buick Regal?

  A: Raising and supporting the vehicle creates space to position a drain pan underneath the transaxle bottom Oil Pan. Start by removing transmission Oil Pan bolts located on the front and sides while keeping the rest of the bolts at the rear loose to just four turns without damaging the mating surfaces. Lightly hit the Oil Pan using a rubber mallet so fluid drains before removing the remaining transmission Oil Pan bolts and the transmission Oil Pan with its associated gasket. Check transmission Oil Pan and filter screen for metal particles, clutch facing material, rubber particles and engine coolant and identify their source for necessary correction. Replacement of a bent or distorted transmission Oil Pan flange is necessary when examining it for damage but attempts to straighten this part should be avoided. Before installing the bottom Oil Pan check if any bolt washers are inverted; replace inverted washers by installing a new bolt assembly when detected. First dry both the Oil Pan and case flanges before cleaning the transmission case until completely dry while the technician dried and cleaned the transmission Oil Pan gasket surfaces until all residual old gasket material disappeared. Place the transmission Oil Pan gasket along with the transmission Oil Pan into their correct position before tightening the transmission Oil Pan bolts to 14 nm (10 ft. Lbs.). The vehicle should be placed at the lowest height during fluid filling with dexron iii transmission fluid while gear selection maintains a park position before engine startup at minimal speed. The transmission should not be filled beyond its capacity to stop foaming while ensuring fluid loss and potential damage do not occur. Fluid volume adjustment needs to be made before checking that all repairs are complete and there are no fluid leaks present.
