Genuine BMW Automatic Transmission Oil Cooler Hose

The Genuine BMW Automatic Transmission Oil Cooler Hose (also called a transmission cooler line or ATF cooler hose) carries automatic transmission fluid between the transmission and the oil cooler. This keeps the fluid at a stable operating temperature during normal driving, towing, and spirited use.

Key Features:

• Original equipment part from BMW, built to the same standards as the hoses installed at the factory
• Designed to carry hot automatic transmission fluid and resist pressure and heat
• Helps the cooling circuit work as BMW engineered it, which protects transmission components from overheating
• Factory-matched design for a proper, leak-resistant connection at the transmission and the cooler

A worn, cracked, or leaking transmission oil cooler hose can lead to fluid loss, overheating, and transmission damage. Replacing it with a Genuine BMW part helps restore reliable cooling and fluid flow. Choose the specific part number that matches your needs from the available options.
