Genuine BMW Transmission Cooling Line

The Genuine BMW Transmission Cooling Line is an original equipment automatic transmission oil cooler line. It carries transmission fluid between the transmission and the oil cooler. This helps the transmission hold a stable operating temperature during normal driving, towing, and spirited use.

Key Features:

• Made to BMW original equipment specifications for a precise fit and reliable sealing
• Carries automatic transmission fluid (ATF) to and from the transmission oil cooler
• Built to withstand heat, pressure, and prolonged exposure to transmission fluid
• Helps prevent leaks and fluid loss, which protects internal transmission components
• Also known as a transmission oil cooler hose, ATF cooler line, or transmission cooler pipe

Replacing a worn, leaking, or damaged cooling line with a genuine BMW part restores proper fluid circulation and cooling. It also helps keep the transmission shifting smoothly and extends its service life. Choose the specific part number that matches your application.
