I usually use steel brake line tubing if going from the tranny to the radiator. Do you have the transmission cooler built into the radiator bottom or are you using a separate cooler? If a separate cooler and you can mount it close to the tranny than just use fuel rated hose. I'm not sure what a C4 has for fittings but I imagine they are 5/16" or 3/8". Someone will be along with more specific sizes I'm sure.

Standard fuel hose will not last very long under the pressure and heat of A/T fluid. I've always gone out of my way to find actual transmission rated hose after the first couple of failures. Even so, only use it for vibration connections. As stated above, steel tubing is the way to go. Most parts stores sell 5/16" tubing which is what would have been originally used on a C-4.

I'm using 5/16 with a separate transmission cooler on my C6. I'm using a bigger than needed cooler because someday before I turn 100, I may get both the truck and the boat resotred and will be towing.
I just bought some steel tubing, invested in a bending tool and a flaring tool (both very good investments) and made my own to fit. I have them connected with rubber hoses and hose clamps.
If you have a transmission cooler in your radiator, you'll need flared tube ends and fittings to connect that.
Here's some pics:
In this picture, the transmission cooler is the large one suspended up on the two runners going across the radiator support.
Below on the frame is the engine oil cooler and remote Frantz oil filter.

I believe it has a transmission cooler built in. A link to the site of it is Radiators, automotive radiators, condenser, oem radiators, truck radiators and it says yes for the tranny cooler, no for the oil cooler.
I'll run up to the parts store to get the steel lines then.

Howdy,
My plan is to use a cooler like this one By Flex-A-Lite and Sold by Summitracing.
I like the idea of it having it's own fan so I don't have to dump heat from the transmission into the radiator.
It's capable of cooling the transmission in a motor home......should be good enough to cool my E4OD....
I still have the steel lines that were used in the F450 the trans came out of. I'll still use flexible hose to connect to the
cooler I'll also have an inline filter too.
Regards,
Rick

If I get a transmission cooler, does that mean that I won't have to run any lines from it to the radiator? Will it also mean that the radiator won't have to work as hard to keep the engine cool?

With a cooler like above you could mount it anywhere you like. You would want to put it somewhere it would not get plugged up with mud etc.
It also depends what you're going to tow (if anything) If you are putting it on a 1/2T pickup and you're not planning to pull a large load like a big boat etc, then you really don't need much cooling capability.
I want to be able to load my F-600 right up to the max load (16,000lbs) so I think I'll need the biggest cooler I can get.

I don't think that I ever plan on towing anything, but who knows what I will do a few years down the road, and I'd hate to run lines again. I'd rather do it right the first time. Plus, I got a radiator that was made for a 289, not 302. The radiator guy (along with some guys on here) said it should work, but I would rather not push the thing to the max. I think I'll try a cooler somewhere closer to the radiator.
As for mud, ya right. My truck will probably be kept inside when it rains, and will never be taken off of a paved road.

One point that occurred to me is that if you position this inf front of ther radiator you will still be transfering heat to the radiator. If that is indeed one of your concerns I suggest you find a way to mount it in a seperate air path. Mounting it driectly in front of the radiator will net approximately the same end results. I had to deal with this issue years ago in an oval track race car.
