Transmission line issues are not something to ignore. A small seep can turn into low fluid, excessive heat, performance issues, and eventually a very expensive repair.
Our 2011–2019 6.7L Powerstroke 6R140 Transmission Line Kit replaces the factory transmission cooler lines with a stronger, cleaner, higher-flow setup. It comes assembled to the proper lengths, uses black anodized billet fittings, includes billet case and cooler adapters, and fits F-250 through F-550 trucks, including cab and chassis models. Great for worn lines, leaking lines, or anyone wanting a cleaner, higher flowing, more reliable upgrade for their 6R140 transmission.
