- Raise and support the vehicle. Place the drain pan under the transaxle oil pan.
- Remove the oil pan bolts from only the front and the sides. Loosen the rear oil pan bolts about 4 turns. Lightly tap the oil pan with a rubber mallet or pry in order to allow the fluid to drain.
- Inspect the fluid color. Remove the remaining oil pan bolts. Remove the oil pan (24) and the gasket (25). See Fig 1 . Remove the oil filter. Use a long screwdriver in order to pry the oil filter neck out of the seal.
- Check the oil filter seal for damage or wear. As needed, remove the seal using the Slide Hammer (J-6125-1B) and the Universal Seal Remover (J-23129). Install a new seal, as needed.
- Before installing, coat the new seal with a small amount of Transmission Assembly Lubricant (J-36850) or petroleum jelly. Install a new filter into the case. See Fig 2 .
- Install the oil pan (24) and the gasket (25) at the same time. See Fig 1 . Install the oil pan bolts. Tighten the bolts to specification. See TORQUE SPECIFICATIONS .
- Lower the vehicle. Fill the transaxle to the proper level. Inspect the transmission fluid level. See CHECKING FLUID LEVEL & CONDITION (4T65-E) . Inspect the oil pan gasket for leaks.
NOTE:
When removing the oil pan bolts, be careful not to damage the oil pan sealing surfaces. Such damage may result in oil leaks in this area.
NOTE:
Oil pan gaskets are reusable. Only replace if sealing surface is damaged.
