ok, i was looking into stuff for my aod that i got... if i remember right its from a 351w 1985 i think... anyways, reading summit on kits. it reads like some of the kits will not let you shift 1-2-3-OD as you go through the gears. some say "1st, 2nd or 3rd and OD" something like that, i dont have the book with me but do any of the aod's do this or what? i dont want to do this and then find out that there is something that im missing and i cant shift through all the gears when im racing/driving my car when ever i want. some also talk like you have to shift down gears when you slow down.
