MINI Oil Cooler - Genuine MINI 24117551091

Product Information

An automatic transmission oil cooler is a heat exchanger that helps regulate the temperature of transmission fluid. It works by circulating the hot transmission fluid through a cooler (often located in front of the radiator or as part of it), where air or coolant lowers the fluid temperature before it returns to the transmission. Keeping transmission fluid cool is essential for preventing overheating, reducing wear, and extending the lifespan of the transmission.

• Overheating transmission – warning lights, slipping gears, or loss of power due to fluid running too hot.
• Fluid leaks – puddles or wet spots under the vehicle near the cooler or cooler lines.
• Contaminated fluid – coolant mixing with transmission fluid (milky appearance) or debris in the fluid leading to shifting problems.

About Genuine Mini

The original parts used by Mini to build your car are available as replacement parts under the “Genuine Mini” brand. Manufactured under the direction of Mini, expect excellent quality and a premium price since these parts are exclusively available through the Mini Dealership network.

You may not realize this, but the parts that make up your Mini are not necessarily manufactured by Mini. No cause for concern, as Mini designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Mini for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Mini parts box and find an OEM branded part inside, simply with the addition of a Mini logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
