3/8″ × 25′ Transmission Repair Hose

Get your transmission running cool again with the 4LifetimeLines® 3/8″ × 25′ Transmission Repair Hose. Designed for automatic transmission fluid (ATF) applications, this hose handles extreme temperatures and pressures, making it perfect for radiator cooler loops, oil-to-air coolers, and custom plumbing on cars, trucks, and performance builds.

Engineered for Durability

Built from a premium synthetic rubber compound, this hose resists swelling, cracking, and kinking from –40 °F up to 275 °F. Its reinforced crush-resistant layer keeps the tube from collapsing when clamped or bent, while the smooth inner bore ensures unrestricted ATF flow and consistent cooling performance.

DIY-Friendly Length & Compatibility

With a full 25-foot coil, you have ample hose to replace both supply and return cooler lines without splicing. The 3/8″ inner diameter matches OEM fittings and aftermarket unions—simply slip on barbed adapters, secure with stainless-steel clamps, and restore leak-free operation on the spot.

Installation & Use

Cut the hose squarely using a fine-tooth blade or hose cutter, install your fittings, and clamp to the transmission cooler or radiator ports. Route away from sharp edges and exhaust heat for long-lasting performance. Because it’s formulated to resist ATF additives, you’ll avoid premature hose failure and keep your transmission running at the right temperature.
