need some input

im runnin a chev 4.3 out of a 1990 s10 in my mazda b2200. i want to switch from a mannual transmission to a auto. what type of tranny should i get? its not stock and i wanna rip down the street and track when im done. thanks.

just have someone build u a th350 or 700r4, but u'll need a different bellhousing

im talkin about a hole new system. the top of the tranny pops up under my dash right now. i have something like a trucker shifter in it. it looks phat and ballin but i takes too long to shift between gears. i want to put a shift kit on it and run a b&m ratchet shifter.

come on guys! I really need too know this. No one has any input? I want to get one to put in in about 2 weeks. please...
