  • Funnel
  • Clean rags
  • Jack and jack stands or ramps

Step-by-Step Procedure

  1. Warm up the engine: Run your Lexus RX 350 for a few minutes to bring the transmission fluid to operating temperature. This ensures better drainage.
  2. Lift the vehicle: Use a jack and jack stands or ramps to safely elevate the front of your vehicle, providing access to the transmission pan.
  3. Locate the transmission pan: The pan is usually located at the bottom of the transmission. Place the drain pan underneath.
  4. Drain the fluid: Carefully remove the transmission drain plug or loosen the transmission pan bolts to drain the fluid. Be prepared for fluid to flow out quickly.

  6. Replace the filter: If your model has a transmission filter, replace it according to the manual’s instructions.
  7. Reinstall the pan: Secure the transmission pan with new gasket and bolts. Tighten bolts evenly to avoid leaks.
  8. Refill transmission fluid: Using a funnel, add the specified amount of new transmission fluid through the transmission dipstick tube or fill port.
  9. Check fluid level: Start the engine, shift through all gears, and check the fluid level with the dipstick. Add fluid if necessary to reach the proper level.
  10. Lower the vehicle: Safely remove the jack stands or drive off the ramps.

Regularly changing your transmission fluid keeps your Lexus RX 350 running smoothly and helps prevent costly repairs. Refer to your owner’s manual for recommended intervals and fluid specifications.
