This tool is designed to safely disconnect the quick-connect fittings on transmission cooler lines without damaging the lines or connectors.

Types of Transmission Cooler Line Removal Tools

I found there are several types of removal tools available. Some are simple plastic or metal clips shaped to fit specific connectors, while others are more versatile, designed to work with multiple sizes and styles. Choosing the right type depends on the kind of fittings on my vehicle’s cooler lines.
