EDIT: I ended up selling the vehicle, but I'll leave all of this up for future use.
So my wife's Acadia's LLT gave up the ghost after 200K miles. I've never liked working on this layout, and have been reading about the I4 LTG to replace the V6 LLT. Used LLT engines command way more than they are worth, and rebuilding one is just putting good money after bad IMO. The LTG makes about the same amount of HP & Torque. I don't have any experience with the smaller motors. Is this a feasible swap from a VCM perspective?
As far as fitment goes, it looks like Chevy used the LTG engine through 2019 in the similar Traverse, albeit hooked to a 9 speed transaxle. I'd just as soon keep the OEM 6T75.
Thanks for any advice.
