150K Mile Toyota: Too Late for a Transmission Fluid (ATF) Change?

Learn how to change the automatic transmission fluid (ATF) on a 2013 Toyota Sienna in this clear, step-by-step tutorial. I’ll walk you through the entire process: safely lifting the vehicle, draining the old Toyota WS ATF, refilling with fresh fluid, checking ATF temperature with a scan tool, and setting the fluid level correctly. This method works for many Toyota models and years that use Toyota WS fluid, including Sienna, Highlander, RAV4, Camry, and more. Perfect for high-mileage maintenance—this Sienna has over 150,000 miles! I’ll also share pro tips to avoid overfilling, ensure proper fluid level, and keep your transmission running smoothly. 📌 Tools & Products Used: * Product Links to XTool Site with 10% Discount: 🛒 Purchase link (A30M V2.0): https://rebrand.ly/xtool_a30m 🛒 Purchase link for XTool D7: https://rebrand.ly/xtool_d7 💰 Discount Code(10% website off): Professor 🌐 Official Website : https://www.xtoolglobal.com/?ref=Professor * XTool A30M on Amazon with 8% Discount: 💰 Discount code (8% off): Z8763DZK 🛒 Purchase link : https://amzn.to/47YEHbx 🛒 New A30M Kit: https://amzn.to/4ba6ciy * Toyota WS ATF: 4 quarts: https://amzn.to/3BIKgNw * Filler Plug Washer, #90430-A0003: https://amzn.to/486XP5t * Drain Plug Washer, #90430-A0002: https://ebay.us/quBnJa * 1/2'' Ratchet: https://amzn.to/3ZrpFWc * Oil Pump for Quart Bottles: https://amzn.to/3J9CGz9 * Impact Socket Set (10mm-24mm): https://amzn.to/4osJd8b, 10mm and 24mm to remove filler cover and plug * Hex Bit Socket Set (2mm-14mm): https://amzn.to/3H2Zmk4, 6mm to remove drain plug and tube As an Amazon Affiliate and eBay Partner, we may be compensated if you make a purchase.
