Dorman 800-736 Automatic Transmission Oil Cooler Line Connector

Automatic Transmission Cooler Line Connector

The Dorman 800-736 automatic transmission oil cooler line connector restores the connection between the transmission and the oil cooler with a direct-fit replacement design. Built from aluminum with a straight profile, it uses a quick disconnect on one end and a male thread on the other for a secure, leak-resistant connection.

Compatible With select Buick Lucerne, Cadillac DTS, Cadillac DeVille, and Pontiac Bonneville applications, this connector is made to match the fit and function of the original part. Dorman 800-736 is a practical replacement when the factory connector is damaged, corroded, or no longer sealing properly.
