High Mileage ATF won't ruin anything or void warranties. It's more robust than the conventional stuff. Even if you don't go with the high mileage, go with a good name brand conventional ATF at the bare minimum.
I'm a fan of Valvoline Maxlife ATF in the E4OD. It's synthetic and high mileage. The best of both worlds in my opinion. Very good stuff. And for the record, I have zero brand loyalty. I'm loyal to what works.
However, if you have a fresh rebuild, the transmission should be clean and all you should do is a drain and refill with your favorite synthetic fluid.
On a side note, have you changed the gear oil in your differential(s) yet?

I'm a fan of Amsoil Severe Gear for the differentials. If you're not towing regularly or doing anything extreme, go with 75w-90. If you are towing regularly or doing extreme stuff, go with 75w-140. Regardless of which brand you go with, follow these guidelines to select the gear oil viscosity and you'll be ok.
