LNJ to LLT or LY7 engine

[kings0987654321]

I have a 07 pontiac torrent 3.4 lnj engine and wanting to swap to LLT or even LY7 the LLT is out of the 10 camera and 09 Cts the LY7 is out of the gxp torrent I will be changing the transmission to preferably the 6 speed f40 awd from 06 Saab or could go rear wheel with the f40 from the g6. What complications will I run into other than engine mounts? EVERYTHING is electrical even the suspension

You would be better off buying a torrrent GXP just saying, also the f40 is a FWD transmission, if you get a donor GXP torrent it would be doable

w/ Killer, finding a donor GXP would probably be your best bet to upgrade, unless you are willing to spend a bunch of money and time.
