Does anyone on this forum know if the lexus/soarer automatic transmittions can possibly be beefed up. I do not want to swap to the V160 manual, I must find away to build the stock auto tranny, larger valves maybe? ANYONE???????? I woud love my stock automatic tranny to be able to support 600hp, I guess from what I hear 450hp is the threshhold with the stock tranny and then second gear goes out on you. My engine hp is getting very close to the tranny limitations, infact I sometimes feel delayed or untimely shifts when riding the nos, it is getting worked over. HELP !!!!
