Hi guys, my zf6 has seen better days, so I figured maybe swap a zf8hp45 from f30, from what i read, the transmission is the same and can be bolt on, but seems like nobody mentioned the transfer case, I remember a dude said i need to swap stock TC from zf6 to zf8, however, from the info I gathered, zf8's ATC35L is stronger than ATC300 from zf6, is there any way to use the trans and TC together. Really want to build a awd beast to compete with audi guys. Any help would be greatly appreciated!
