tranny hunting

my BA-10 is slipping away- been all over craigslist and came across some good deals on wrangler transmissions. does anyone know if its a bolt on affair? my concern is i want a newer trans but its going in a renix. thanks for the advice-

Get ahold of Avanteone, if I remember right, he may have an AX15. Might want to try asking in the NWC For Sale/Wanted forum.
