Race car? Street car? OEM? What cooler? Where is it mounted? What trans?
If the results don't match the theory, change the theory.

-6 teflon lined hose - like Aeroquip's TFE, .320"ID - with appropriate fittings and adapters. Use a cooler with threaded connections. The old rubber hose and hose clamps on barbed fittings are no good and create a huge mess when they blow apart.
I've mounted this stuff under the car, sometimes with a cooler with a small dedicated fan for the really abusive combinations, with good results. Saves all the plumbing and crap at the front of the car.
I've used -5 stuff when using it as connections for 5/16 tubing, but that stuff is oddball. -6 is much easier.

3/8" Bundyweld brake line with compression fittings and very short pieces of braided line where needed for small bends. Using 3,000 psi stainle$$ braid for a cooler line is a bit overkill....

That will work IF the steel line is properly flared and/or adapted to AN or SAE and the hose installed using the correct threaded fittings. Hose clamps on braided hose is a mess looking for a place to happen. I'm OK with overkill if it means I don't have to worry about it failing.

You can order 1/4 NPT to #6 AN male adapter fittings and use #6 AN hose ends on #6 AN PTFE lined (Teflon) hose to make your own flexible tranny cooler lines I do on my race cars

well, just to be sure my feeble old mind wasn't spouting BS information, i went out into the shop and checked a 727 that was on the cart. it is indeed 1/8" NPT thread for the cooler lines. hopefully, there was no confusion caused.

How high is the pressure in the cooler lines ? Maybe 5-100PSI depending on the trans and how it's set up. Not much, but the chemicals in the oil and the heat need to be taken into consideration when choosing hose material and construction. Even the rubber lined AQP style hose is questionable. There are -6 x 1/8" NPSM fittings available which rely on a gasket to seal vs. pipe thread. Helps eliminate the possibility of cracking a case from over tightening NPT fittings.
If the results don't match the theory, change the theory.
