Replace your rusted early 99-03 7.3L Ford Powerstroke transmissions lines with an upgraded CNC Fabrication stainless steel line kit.

This kit is to replace your factory 4R100 transmission cooler lines for those that have already installed 6.0L Powerstroke transmission cooler that has 1/2 inch ports.

If you need transmission hose, we recommend the Gates 27066 as that hose works very well with Parker PushLok barb fittings.

Note: Please be mindful that these lines are one piece, 60 inch long, and there is a chance they may get slightly bent by the shipping company. This tubing is extremely durable and can easily be bent back into shape.

If you have NotT installed a 6.0L Powerstroke transmission cooler with the 1/2 inch ports, then purchase part number 425007 (with 3/8 inch fittings to match the factory cooler)

We recommend by-passing or removing the lines going to the bottom of the radiator. When the heat exchanger inside the radiator fails, it will send coolant into your transmission and will cause the transmission and torque converter to fail.

It is not year specific on whether Ford had the ports in the radiator as we have seen on many years of truck in the shop not have them.

  • Fits Early 99 through 2003 7.3L with the 4R100 Transmission
