Is your Toyota's transmission running hot or leaking? This Dorman Automatic Transmission Oil Cooler (part #918-240) is a direct replacement designed to fix that. Its main job is to cool down the automatic transmission fluid (ATF), which is crucial for preventing overheating that can lead to expensive transmission damage and leaks. It's built from durable aluminum with a special coating that gives it high corrosion resistance, so it can handle the elements under your car. Because it's engineered as a direct OE replacement (fits models that used OE number 32910-34020), it should bolt right into place without any fuss for a proper fit. Dorman puts these through rigorous quality control, so you're getting a reliable part. It's often recommended to replace the cooler when you're replacing the transmission itself, but it's also a solid fix if your old cooler is clogged or damaged. A relatively simple part that plays a big role in keeping your transmission healthy and your car on the road longer. Always double-check compatibility with your specific Toyota model and year.
