Replace your leaking transmission lines in your 1999-2003 7.3L Powerstroke with the precision-engineered CNC Fabrication 4R100 Transmission Cooler Line Kit. Designed for optimal performance and durability, this kit offers a seamless installation process and ensures efficient transmission fluid cooling, even under demanding conditions. Whether you're towing heavy loads, hauling, or simply looking to enhance your vehicle's reliability, the CNC Fab Transmission Cooler Line Kit is the ultimate solution. This kit is available for trucks with factory transmission coolers that utilize 3/8" hose barbs, and for those that have upgraded to a 6.0L Powerstroke transmission cooler that utilizes 1/2" ports.
IMPORTANT NOTE:
IMPORTANT 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
- CNC recommends bypassing 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.

Cute gift!
Color: A1 - Pink 1 Pack
Perfect to travel with or throw in sports bags. Purchased for my athlete college student and she keeps it in her basketball bag to take jewelry off before practice and keep everything safe and untangled. There’s a spot for every type of jewelry. It’s sturdy, closes and seals and if perfect!

Adorable, functional, and great for travel
Color: A1 - Pink 1 Pack
Adorable, good quality, small but fits enough for travel. I’ve had no problems with the zipper or any of the inside functions. I like that you can remove one of the pieces to fit something larger in it.

Perfect size and quality

This was a gift for my teen daughter she’s collecting jewelry now and this was perfect for her. This is also great for traveling! It holds lots of little pieces and feels soft. This is a great gift idea. Months later and it’s still in great condition. Easy to use and take along anywhere.
