REMOVAL & INSTALLATION



  1. Raise and safely support the vehicle.
  2.  
  3. Drain the transaxle fluid.
  4.  
  5. Carefully loosen and remove the bolts holding the oil pan. Tap around the pan lightly with a plastic mallet, breaking the gasket tension by vibration. Do not pry the pan down with a screwdriver or similar tool; the pan is lightweight metal and will deform, causing leaks.
  6.  
  7. Remove all traces of gasket material from the pan and the transaxle mating faces. Clean then carefully with a plastic or wooden scraper. Do not gouge the metal.
  8.  
  9. Clean the pan thoroughly of all oil and sediment.
  10.  
  11. Remove the bolts holding the screen (filter) and remove it from the car. Note that the bolts holding the filter may be different lengths; they must be replaced in the correct positions at reassembly.
  12.  

To install:
  1. Install the filter and tighten the bolts to 89 inch lbs. (10 Nm).
  2.  
  3. Install a new gasket on the pan and bolt the pan into place. Snug the bolts in a crisscross pattern, working from the center out. Tighten the pan bolts to 44 inch lbs. (5 Nm).
  4.  

If the mating surfaces of the oil pan and transaxle are clean and straight, there is no need for gasket sealer during reassembly. The use of sealer is generally not recommended on these transaxles.

  1. Lower the vehicle to the ground and refill the automatic transaxle fluid.
  2.
