  Q: How to service and repair the transmission pan on Chevrolet Lumina?

  A: Service and repair procedures start by properly raising and supporting the vehicle during which you should place a drain pan under the transaxle bottom Oil Pan. Begin by safely removing the Oil Pan bolts from both front and side aspects before loosening the rear Oil Pan bolts about four turns with caution towards avoiding damage to the Oil Pan and case mating surfaces to stop oil leaks. Tap the Oil Pan gently with a rubber mallet while leaving a screwdriver to work as a pry tool. This action permits the liquid to exit before you take out the remaining Oil Pan bolts and Oil Pan together with the gasket. An examination of the Oil Pan combined with filter screen must happen to identify any foreign materials such as metal particles, clutch facing material, rubber particles, and engine coolant so their source of contamination can be found and fixed. The Oil Pan flange must be checked for distortion before replacing the Oil Pan unless congratulations can be made to regain its original shape. You should replace the bolt and washer assembly when the washer shows an inverted orientation. The clean process requires dry and oil-free Oil Pan and case flanges which must be solvent-cleaned alongside the removal of all old gasket particles from surfaces. Set the Oil Pan Gasket correctly before mounting the Oil Pan while tightening the Oil Pan bolts to 14 nm (10 ft. Lbs.). Fill the transaxle with proper quantities of dexron(R) iii fluid after lowering the car and engage the park position from the gear selector while letting the engine idle slowly. Transaxle damage will result if you exceed the recommended fluid capacity level since this can lead to foaming and fluid loss along with shift complaints. Check the fluid level before conducting a final inspection for correct work completion as well as monitoring any possible fluid leakage.
