Description

The Dorman 66219 is a transmission oil cooler seal designed to eliminate leaks where the oil cooler line connects to the transmission. Gaskets can degrade over time, leading to leaks, so this part should be replaced whenever the oil cooler line and transmission are separated. Its durable rubber-over-steel construction ensures a positive seal and retains its shape. This is a direct replacement part that fits and functions like the original equipment and is easy to install without special tools.
