Default transmission recomendations?

Just had transmission rebuild but am realizing it wasn't built for enough power & on top of that I've just added spray :-(
Any guidance what to look for & what to avoid? My signature summarizes my cars mods & power, I would like something scalable to support 750+ rwhp that is cost effective (I will probably get laughed at for saying cost effective but have to ask anyway). I'd like to keep automatic not do a swap to manual unless for some reason it makes sense.

Thanks in advance for the guidance / direction.

flt and performabuilt have great 4l60e's doing 750 hp, but if you dont care about OD, then i would say a th400, there is also the 4l80e if you do want OD but dont want the 4l60e, hope this helps you,

I'd do a 4L80 and be done with it. Jake's Performance specializes in them.

about 750hp is the limit of stock parts in them (depends on weight too) with a good rebuild. current upper limit is around 1500hp (soon to be 2000+)

To do a 4l80 you would have to upgrade your computer or add a harness to it. Do a lv2 tranny thats all you need.
