Knowledge about shift kits for AOD's?

If you want to shift manually, without having to shift back to 2nd, it will cost you $350 for the valve body. A shift kit will only change the firmness of the shift. A transgo valve body will change the 2/3 shift to a 3/4(od) shift. A lentech valve body($350 min) will allow you to hold each gear to the desired rpm, kinda manual(depends on how you look at it). You can also leave it in drive and let it shift itself if you want. The lentech(what I have now, love it!) also makes the 3 gear selections on the stick and has a switch for od. That is for the AOD. The AODE is somewhat different, from what I hear. What year car do you have?
