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.

Because under normal conditions that is all they needed to be.
Those 1/8 fittings can be drilled out some for more flow if you would like, but it won't make much difference.
Also don't forget that they are 1/8 at the radiator as well.
You will also not adversely affect anything to increase the cooler system flow as far as the trans function goes.
