Summit Racing™ Flexible Automatic Transmission Cooler Lines

4.63 out of 5 stars 76 Customer Reviews

Summit Racing™ flexible transmission cooler lines make cooling your automatic transmission easy. These lines come with all the necessary fittings to run your lines from the cooler to the transmission. The PTFE-lined braided hose is made from heavy-duty 304 stainless steel braids that offer premium strength and flexibility to prevent the hose from breaking down. Quality anodized aluminum hose ends and fittings create a perfect seal to ensure your transmission gets the fluid it needs. Simplify your installation with one of our flexible line kits.
