For 1990-2009 cars

1. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
2. Place a drain pan or a suitable container under the transaxle fluid pan.
3. Remove the transaxle drain plug (1) from the transaxle fluid pan (3), and drain the transaxle fluid.

Important: Note the position of the 2 bolts with cross-recessed heads for proper installation.

4. Remove 15 bolts, the transaxle fluid pan guard (2), and the fluid pan from the transaxle.

Notice: When removing the transaxle fluid pan, use caution in order not to damage the transaxle case-to-fluid pan mating surfaces. If the fluid pan is frozen to the transaxle case, use a rubber mallet and a wood block to lightly tap the fluid pan free. Do not attempt to pry the fluid pan away from the case with metal tools; damage to the case or fluid pan flange could result.

5. Remove the fluid pan gasket from the transaxle.
6. Remove 6 bolts and the fluid filter screen (1) from the valve body. Note the position of the solenoid wire clamp (2) for proper installation.

Important: A small amount of clutch material in the bottom of the transaxle fluid pan is a normal condition and is consistent with normal transaxle wear. The bottom of the fluid pan has a magnet that will collect metal particles. However, if large amounts of clutch material, of metal particles, or of other material are present, disassemble and inspect the transaxle.

7. Inspect the bottom of the fluid pan for any large pieces of metal or for other material.
8. Clean the fluid filter screen with solvent, and dry thoroughly. If the screen mesh is damaged, replace the filter screen.
9. Clean the transaxle fluid pan magnet (2) and the bottom of the transaxle fluid pan (1).
10. Clean the gasket material from the fluid pan-to-case mating surfaces (1).

### Installation Procedure

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

1. Install the fluid filter screen (1) to the valve body.Verify that the solenoid wire clamp (2) is in the correct position. Secure the screen with 6 bolts.

Tighten
Tighten the fluid filter screen bolts to 6 N·m (53 lb in).

2. Install the new fluid pan gasket on the transaxle fluid pan.

Important: The fluid pan contains 15 bolts. Two bolts have cross recessed heads. Apply some GM P/N 12346004, or the equivalent, to the threaded portion of the 2 bolts, and install the bolts in the correct positions. Do NOT apply the sealant to the 13 bolts that remain.

3. Install the new fluid pan gasket (1), the transaxle fluid pan (2), and the transaxle fluid pan guard (3) to the transaxle. Verify that both of the cross-recessed bolts are in the correct positions. Secure the fluid pan components with 15 bolts.

Tighten
Tighten the transaxle fluid pan bolts to 6 N·m (53 lb in).

4. Install the transaxle pan drain plug into the fluid pan.

Tighten
Tighten the transaxle drain plug to 23 N·m (17 lb ft).

5. Remove the drain pan from under the transaxle fluid pan.
6. Lower the vehicle.
7. Refill the transaxle, as necessary.Refer to Transmission Fluid Check
