BMW Automatic Transmission Cooler Hose Inlet - Genuine BMW 17221177654

Product Information

An Automatic Transmission Oil Cooler Hose is a component in vehicles with automatic transmissions that transports transmission fluid between the transmission and the transmission cooler, often located near the radiator. This hose helps keep the transmission fluid cool by circulating it through the cooler, which is essential for maintaining optimal transmission temperature, preventing overheating, and ensuring smooth shifting and transmission longevity.

• Transmission Fluid Leaks: A damaged or worn hose can leak transmission fluid, which may appear as red or brownish spots under the vehicle, particularly near the front
• Low Transmission Fluid Levels: If there is a leak, the fluid level will drop, causing performance issues such as rough or delayed shifting and even overheating
• Transmission Overheating: The cooler hose keeps fluid temperatures down, so a faulty or blocked hose can lead to overheating, which may trigger a warning light on the dashboard

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW 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 BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.
