• Q: How to replace the transmission pan on 2004 Buick Regal?

  A: You should begin pan replacement by first elevating the vehicle while placing a drain pan beneath the transaxle Oil Pan. Begin by removing the bolts secured to the transaxle Oil Pan at its front side followed by carefully releasing back bolts. Prevent damage to the Oil Pan surface which connects to the case because this could lead to oil leakage. A rubber mallet or screwdriver should be used to slowly separate the Oil Pan from its position while the fluid drains out. Complete the bolt removal process of the transaxle and extract both the Oil Pan while separating the gasket from it. Life pan and filter analysis must include the detection and repair of metal particles, clutch facing material, rubber particles and engine coolant. The cause of any contamination should be identified at this stage. You must exchange the Oil Pan flange if it shows any signs of bending or warping because attempts at straightening it will be unsuccessful. The procedure to remove bottom oil requires checking all Oil Pan bolt washers for correct orientation and replacement of any inverted ones. Dry and oil-film-free conditions must be present on both the Oil Pan and case flanges before cleaning the case followed by airspace drying. Wipe off gasket surfaces on the Oil Pan before drying them completely without leaving any residue from the old gasket material. Place the Oil Pan gasket along with the Oil Pan inside the opening before attaching the Oil Pan bolts at 14 nm (10 ft. Lbs.) torque value. The vehicle must be lowered and dextron iii should be added to the transaxle unit when the gear selector points to park. After starting the engine operate it with slow idle without racing before checking the fluid level while searching for any potential leaks.
