5.9L Cummins Braided Transmission Line Kit | Full Send Diesel FSD-11-B
Replace leaking factory transmission lines on a 2003–2007 5.9 Cummins that already has a Mishimoto cooler. Full Send Diesel FSD-11-B is a black braided AN line kit made for the Mishimoto MMTC-RAM-03SL transmission cooler. It threads into the 48RE and the cooler, skips hose clamps, and bypasses the factory heat exchanger on the driver side of the block so trans fluid goes straight to the cooler. Factory rubber lines crack and rust. This kit is built to stay leak-free and look clean under the hood.
Key features
- Black nylon braided hose with billet AN fittings
- Made for the Mishimoto MMTC-RAM-03SL transmission cooler
- Bypasses the factory block-mounted heat exchanger
- No hose clamps
- Leak-resistant AN connections at the transmission and cooler
- Cleaner underhood look than stock rubber lines
- Lifetime Full Send Diesel workmanship warranty

Cooler, transmission fluid, and line clamps / zip ties for routing are not included.

Mark line routing before you pull the old hoses. Install the AN adapters, route the new lines so they cannot rub or rest on the exhaust, then fill and leak-check with the correct ATF. If a 2003–2007 5.9 Cummins has a Mishimoto cooler and leaking stock lines, Full Send Diesel FSD-11-B is the braided bypass kit built for that setup.
