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 for heavy duty chewers
Flavor Name: Steak, Size: Medium
Our two dogs love these bones. They’re very durable for heavy duty chewers and it takes them a fairly good time to get through them. They must love the taste because it’s the bone they first pick up. I’ve gotten two flavors so far, beef and the peanut butter. Our dogs love them and because of that so do we.

Seems great, but not for my lab
Flavor Name: Bacon, Size: Medium, Flavor Name: Bacon, Size: Medium
I am rating this, to some degree, from a hypothetical standpoint. It SEEMS like a great bone. It SEEMS like it will last quite a while and withstand some avid chewers. However, I can't say for certain because it just wasn't well-loved by my Black Lab.
She has a penchant for chewing animal bones. She loves to find wildlife bones in our yard and munch on them, so we do our best to provide healthy chewing options in the house. She will go to town on a cow's joint and even enjoys a peanut butter filled Kong from time to time, but this bone just didn't meet her expectations.
It's not a bad bone. It has a very rugged feel and seems like it would be safe if bits and pieces were to begin coming off, like they're safely edible. I guess (and I can't say for sure..) it just doesn't have as much of a meaty flavor as many dog's like. If your pup is a Nylabone chewer- or likes to chow down on your loafers- this bone may be a perfect new addition to his/her toy bin.

Bone for destroyers
Flavor Name: Bacon, Size: Small
4 months ago I Bought this bone for my 90lb lab who destroys all his bones, but not this one! It barely has any teeth/chew marks on it and it’s one of his favorites. It was a great find and I’ll be sure to buy again. If you have a dog that destroys bones I’d give this one a try.

Immediate Doggy Happiness!
Flavor Name: Bacon, Size: Medium
Great dog bones! These are a nice size for my 55-pound Aussie, as well as our 96-pound Alaskan Shepherd. They are big enough to last for a while, and big enough to see so that I don't step on them with my bare feet; part of this is that they stick up off the floor a bit, instead of being a flat bone, all in one plane.
