Overview

It circulates hot fluid through a cooler, typically located in front of the radiator, to lower its temperature before returning it to the transmission. This process is crucial for preventing overheating, reducing wear, and extending the transmission's lifespan.
Show original supplier description
This URO Parts transmission oil cooler attaches to the radiator and functions as a heat exchanger to cool the automatic transmission fluid. It is designed for specific BMW models including the F22/F23 230i (2017-2021), F30/F31/F34 330i (2017-2019), and F32/F33/F34 430i (2017-2020). This cooler is compatible with both rear-wheel drive and xDrive variants of these vehicles. The Genuine BMW part number for this component is 17218514515. The product is manufactured in Austria and is considered a Genuine BMW quality part. Transmission cooler line sets are available separately and are recommended for a complete installation. The BimmerWorld listing also provides a comprehensive list of compatible BMW fitments, detailing specific series and models along with their relevant years. Maintaining optimal transmission fluid temperature is vital for vehicle longevity. Overheating can lead to transmission slipping, loss of power, and accelerated wear. Fluid leaks around the cooler or lines, or signs of contamination in the transmission fluid (such as a milky appearance), can also indicate a failing cooler. This part serves as a direct replacement or upgrade to ensure proper thermal management of your automatic transmission.
