Refer to Fastener Notice .

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.

• | The new fluid filter screen gasket.

• | The fluid filter screen (1).

• | Use the three fluid filter screen bolts (2), in order to secure the fluid filter screen.

Tighten
Tighten the front propeller shaft bolts and nuts to 50 N·m (37 lb ft).

4. Lower the vehicle.
5. Use the following procedure in order to refill the transmission if necessary.

• | Place the vehicle on a level surface.

• | Remove the fluid level indicator.

• | Add approximately 1.5 liters (1.6 quarts) of automatic transmission fluid into the fluid filler tube.

• | Use Dexron® III automatic transmission fluid GM P/N 12346143 or the equivalent.

• | Install the fluid level indicator into the fluid filler tube.

• | Apply the parking brake and block the vehicle wheels.

• | Start the engine with the engine selector level in the PARK position.

• | Do not race the engine.

• | Perform the following procedure with the engine running at idle:

- | Remove the fluid level indicator.

• | Reinsert the fluid level indicator into the filler tube.

• | Verify that the indicator is seated in the indicators original position.

• | Remove the fluid level indicator in order to inspect the fluid.

• | The fluid level should measure between the FULL HOT and LOW HOT marks.

• | If the level is below the LOW HOT mark then add fluid in order to raise the fluid level to the FULL HOT mark.

• | Raising the fluid level from the LOW HOT mark to the FULL HOT mark requires 0.3 liters (0.3 quarts) of fluid. Use Dexron® III automatic transmission fluid GM P/N 12346143 or the equivalent.

• | Conduct a road test.

• | Inspect the transmission fluid level. Refer to Transmission Fluid Check .
