automatic transmissions don't work that way. They have a planetary gearset so you can't change one gear without changing all the others too. And as far as I know, the only other gearset you could use would be the AOD, which has a .67 top gear instead of a .70, but first and second in the 4R70 are much steeper, so you would lose a lot of acceleration doing that, all for practically nothing on top end.
