how do I know if my Toyota RAV4 XA40 (2013-2018) transmission fluid needs changing

Solution

1. Preparation

• Gather Tools:
  • Funnel
  • Transmission fluid pump
  • Clean rag
• Safety Warnings: Ensure the vehicle is on a flat surface and the engine is cool before starting.

2. Drain Transmission Fluid

• Locate Drain Plug: Find the transmission drain plug under the vehicle.
• Remove Drain Plug: Use a socket wrench to remove the drain plug and allow the old fluid to completely drain into a suitable container.
• Clean Drain Plug: Wipe down the drain plug with a clean rag before re-installing.

3. Replace Transmission Fluid

• Reinstall Drain Plug: Reinsert and torque the drain plug to the manufacturer’s specifications (usually around 30-40 ft-lbs).
• Add New Fluid: Using a funnel, pour the recommended type of transmission fluid (usually Toyota ATF WS) into the dipstick tube or designated fill port, following the amount specified in the owner's manual.
• Check Fluid Level: After adding fluid, check the level again using the dipstick, ensuring it falls within the correct range.

4. Test Drive

• Start the Engine: Allow the engine to run for a few minutes.
• Shift Through Gears: Cycle through all gear positions (P-R-N-D) and back to park, then check the fluid level again and top off if necessary.
