This fitted my 2004 Chevrolet Malibu Transmission Cooler Lines exactly and they fitted perfectly. I am very glad I bought 2 new fittings (these Dorman 800-619) when replacing the transmission coolant lines as the old ones were so tight and/or seized that I damaged them when I replaced the transmission coolant lines . These fittings/connectors offer Revain good value and are cheap insurance against leaks when installing new transmission cooler lines.
