Remove the transmission fill plug located on the side of the transmission.
Use a funnel to add the manufacturer-recommended transmission fluid.
Replace the fill plug and ensure it is secured.

3. Inspect and Replace Clutch Components

Tools Required: Socket set, torque wrench, clutch alignment tool

Remove the transmission from the vehicle:
- Disconnect the driveshafts and any electrical connections.
- Unscrew the transmission bolts and carefully lower the transmission.
Inspect the clutch disc, pressure plate, and flywheel for wear:
- Look for signs of glazing or significant wear on the clutch disc.
- Check the pressure plate for cracks or warping.
Replace any worn components:
- Install a new clutch disc and pressure plate, ensuring alignment with the clutch alignment tool.
- Torque the pressure plate bolts to the manufacturer's specifications.
Reinstall the transmission:
- Carefully lift the transmission back into place and secure it with bolts.

4. Bleed the Clutch System

Tools Required: Brake bleeder kit

Locate the bleeder valve on the clutch slave cylinder.
Attach the brake bleeder kit and ensure the fluid reservoir is filled with the appropriate brake fluid.
Open the bleeder valve and pump the clutch pedal until no air bubbles are visible in the fluid.
Close the bleeder valve and check the fluid level, topping off if necessary.
