Thank you both for responding to my message!
I will certainly reach out to a Service Center Rep/Advisor before finalizing any online purchases! I guess I just thought they would withhold that information since I'm not looking to have them do the repair/installation.
@Ncsugrad2002 Thanks for doing the hardwork lol. As mentioned above, I have the Hybrid model and I wanted as much information as possible since online listings (eBay, etc.) note that 15' and 16' Hybrid Transmissions don't match up to work on my 13' FFH. For the most part, I assumed it was just eBay listers covering their tail since retrofitting a newer transmission can be questionable.
I've also been trying to expand my search options by seeing if the MKZ and C-Max Hybrids utilize the same transmission (since parts are becoming harder to find).
