Transmission Cooler Lines

Keep your automatic transmission running cool and reliable with high-quality transmission cooler lines. Whether you’re replacing worn factory lines or upgrading for better flow and durability, the right cooler lines help prevent overheating, fluid breakdown, and costly transmission damage.

Available from brands like Classic Tube, Dorman, Sunsong, The Right Stuff, and more, our selection includes flexible transmission cooler lines, braided transmission cooler lines, and pre-bent transmission cooler lines designed for most popular transmissions. These lines deliver consistent fluid circulation between the transmission and cooler for optimal temperature control under daily driving, towing, or performance use.

Flexible Transmission Cooler Lines

Flexible transmission cooler lines offer easy routing and installation in tight engine bays. Made from durable materials that resist heat, abrasion, and pressure, they provide a reliable, leak-resistant connection while allowing for engine movement and vibration.

Braided Transmission Cooler Lines

For maximum strength and protection, braided transmission cooler lines feature a tough outer braid (typically made from stainless steel or nylon) that guards against abrasion, heat, and external damage. These lines are ideal for high-performance builds, heavy-duty applications, or vehicles that see extreme conditions.
