## Overview

The Dorman 800-605 Transmission Cooler Connector is a high-quality, OE-matching replacement part designed to ensure leak-free, durable performance between your vehicle’s transmission and oil cooler. Made from premium rubber materials and pressure-tested for reliability, it’s an essential accessory for professional-grade transmission maintenance and repair.

## Description

Made of quality materials, this automatic transmission oil cooler line connector matches the fit and function of a damaged original equipment connector to restore leak-free performance between the transmission and the oil cooler.

Review: Compatible with radiator on my 2000 Buick Lesabre 3.8 - The Jiffy Clips holding transmission lines connected sometimes cannot be removed, even using the correct tool. I got three of the four clips on my lines off, but for the last I had to cut the pipe with a Dremel cutoff wheel and then remove this fitting from the radiator using a socket wrench. The factory fitting is extremely tight in the radiator and take a lot of force to unthread and remove from the radiator. However, with sufficient torque the fitting will come out without damaging the radiator. A LOT of torque to remove. These Dorman replacement fitting come with thread sealant already installed, and the thread right in easily. The standard GM transmission line metal pipes fit right in and seal properly. Note: It may not be obvious, but the Jiffy Clips are designed to not have to be removed. The removal tool fits around the pipe and spreads the clips without removing them. The pipe pulls out through the removal tool. To connect the pipe to the fitting, just push it in with the Jiffy Clip already in place. It will go in and lock.
Review: No o ring? - Does not come with o ring?
