FSD Braided factory replacement transmission line. We now sell our AN braided replacement lines individually. This line replaces Number 3 in the diagram above.

From the front port on the transmission to the heat exchanger mounted on the side of the block. Our lines are made from an extremely durable braided hose and billet aluminum fittings. As always this hose is backed by FSD's lifetime workmanship warranty, meaning if this line fails for any reason that is a fault of ours.

We will send you a new one free of charge.

What's included?

• 2003-2007 Dodge Cummins
• Factory Replacment Transmission Line Number 3
• (1) Replacement transmission line
• (1) Billet fitting for the transmission and cooler

Note: This kit includes everything you need to replace your factory hose. Modification to the factory transmission cooler is necessary using our kit. You must trim the tip of the cooler off so that our compression fitting can slide all the way on and seal. It is a bit more work but it's much safer then using rubber hose and hose clamps.
