School me on trans basics

Any trans gurus know why the factory adapters are only 1/8"?

Maybe to intentionally reduce flow to cooler and put more back in the pan until fluid is warmer?

I don't want to mod on assumptions and causes headaches later.

No idea why they did that then but when the late 80's early 90's overdrive trans (A-500 and A518) came out they had the cases drilled out to 1/4" pipe and used 1/4" pipe fittings with 3/8" cooler lines. Maybe they figured out slightly larger lines produced more coolant flow and kept it cooler?? Just a guess
