Product Name: CNC Fabrication 4R100 3/8 Inch Transmission Cooler Line Kit with 3/8 Inch Barbs - 99-03 Ford Powerstroke 7.3L Manufacturer: CNC Fabrication Manufacturer Part #: 425007 Thoroughbred Diesel Part #: CNC425007 Fitment Notes: 1999-2003 Ford Powerstroke 7.3L
98.5-03 7.3L CNC Fabrication, LLC 4R100 Transmission Cooler Line Kit
This kit is to replace your factory 4R100 transmission cooler lines with 3/8" hose barbs to match the factory transmission cooler ports.
CNC Fabrication 4R100 3/8 Inch Transmission Cooler Line Kit with 3/8 Inch Barbs Features:
NOTE:
If you need transmission hose, we recommend the Gates 27059 as that hose works very well with Parker PushLok barb fittings.
Please be mindful that these lines are one piece, 60" 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 already installed a 6.0L Powerstroke transmission cooler with the 1/2" ports, then purchase part number 425107
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.
