Mark,
I think my '96 has 5/16" transmission oil cooler lines and Ford went to 3/8" lines at some point. Is there any measurable practical advantage to upgrading to 3/8" tubing? I can bend tubing so the out of pocket cost is pretty minimal.
Thanks

So Mark, should a high restriction develop in the cooling line, can you say what the signs / consequences would be? I'll be sure to keep that extra filter I mentioned fresh.

Yeah, on my '96 I don't have the connecting line, so I guess not a relief bypass valve either.

Consequences of a high restriction in the cooling line in towing service would likely result in a burned up transmission.

I disagree, especially if you replace the air to oil cooler with a larger cooler. It will flow more fluid.

I'm just quoting John Woods who gave me a lifetime warranty. I also have a 32 row 6.0 trans cooler. Awesome! LOL

I know you are, and I disagree with John. 3/8" lines will have less flow restriction than 5/16" lines, so there will be more flow to the cooler.
