727 Auto tranny question

Can't take pics. No camera,. I'll explain it though. There's a metal braket or something that the shifter cable goes through under the car, it's attached to the Tranny cover. There's 2 11/16 nuts that are on the shifter cable. I adjusted those and the tranny started shifting again. But none of the gears were right. I kept adjusting them, and it's close, but the trans has a lag when shifting, and sometimes won't shift from 1st to second, or even down shift for that matter. But it goes into reverse perfectly.
