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.

Great fit
Size: 36W x 32L, Color: Dark Khaki
My boys love these pants. College son prefers them when he is golfing. They fit well and are comfortable. He usually wears southern tide brand which are extremely pricey. So happy to have found these. Already ordered in multiple colors. They are nice and thin for Florida weather

Great Pants
Size: 31W x 28L, Color: Black
I wasn’t sure what to expect when I ordered these, but I’m really glad I did. The pants look even better in person than in the photos , the color is accurate and the fabric has a nice, quality feel to it. The fit is spot on.
I bought it in 3-4 colors.

Decent for the price, but inconsistent quality
Size: 33W x 29L, Color: Dark Grey
Quality can be hit or miss. I ordered several pairs of the same "model" and fit is inconsistent. One pair fit great, another pair of a different color felt 3 sizes too small. Leg width can be slightly different from pant to pant or the legs have a bit of a "twist" sewn in them.
For the price, I'm not expecting perfection.

Works amazing
Color: Dark Green
I’m extremely happy with this Wireless Charger Stand Charging Station! The 3-in-1 design is super convenient and keeps all my devices organized in one place. It charges my phone, smartwatch, and earbuds quickly and efficiently without needing multiple cables everywhere.
The stand is sleek, compact, and looks great on my desk and bedside table. I also love how easy it is to use — just place the devices on the charger and they start charging instantly. The build quality feels sturdy and premium, and the charging is reliable every time.
This has definitely made my daily routine much simpler and cleaner. Highly recommend it to anyone looking for a fast, convenient, and stylish charging solution!
