holley 4010 kickdown?

thanks. thats what I thought that i'd have to also buy the throttle cable. but wasn't too sure. now you guys confirmed it..

is there anything bad about driving my automatic column shift car manually shifting through the gears? going 1st, 2nd, then drive.?

because seems when I do this, the tranny doesn't slip at all. but when i just try to drive in Drive, it slips while shifting between 2nd and 3rd gears..
