Without a pre-flush, those deposits immediately contaminate your fresh ATF. Using LM20224 before the drain suspends and removes that residual contamination, so your new fluid starts clean and stays clean longer. It’s a $35 step that protects a $3,000–$8,000 transmission.\n\u003c!-- BIDIR HUB LINK: Link to LIQUI MOLY transmission care collection or related products here --\u003e\n\u003c\/div\u003e","brand":"LIQUI MOLY","offers":[{"title":"Default Title","offer_id":52320183648545,"sku":"20224","price":34.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0897\/7783\/2225\/files\/Pro-Line_Automatic_Transmission_Cleaner_20224_1L.png?v=1781728221","url":"https:\/\/xpartsupply.com\/products\/pro-line-automatic-transmission-cleaner-lm20224-1l","provider":"XPart Supply Ltd.","version":"1.0","type":"link"}
