Installation Procedure

1. Preparation: Ensure the vehicle is parked on a level surface and the engine is cool. Disconnect the battery to prevent accidental electrical discharge.
2. Drain Transmission Fluid: Place a suitable container beneath the transmission pan, remove the drain plug, and allow fluid to flow out completely.
3. Remove Old Filter: Unscrew the existing filter using an appropriate wrench. Dispose of the old filter according to local regulations.
4. Install New Filter: Apply a thin layer of fresh transmission fluid onto the gasket of the new W 9023/1 filter. Screw it in by hand until snug, then tighten with a torque wrench to the manufacturer’s specified value (typically 15–20 Nm).
5. Refill Transmission: Reinstall the drain plug and fill the transmission with the recommended fluid type and volume.
6. Check for Leaks: Start the engine, allow it to reach operating temperature, and inspect around the filter area for any signs of leakage.

Maintenance & Service Tips

• Replace the filter at every fluid change or as per the vehicle’s maintenance schedule.
• Avoid using low‑quality fluids that may accelerate filter clogging.
• Inspect the gasket for wear before each installation; replace if damaged to maintain a proper seal.
• Store unused filters in a dry, cool environment to preserve media integrity.
