I bought an October build Summit - anything I should update?

So I was at the dealer last Saturday ready to buy and had a choice between a Jan 14 build with CD Player (which I dont need and eats up most of the already small space in the center console) or an Oct build with no CD Player. Or I could order, which I really didn't want to do since they had my color combo in stock and ready to roll.

A friend at work said to get a Dec or later build bc there was some sort of update to the tranny firmware in November that improved something. Is this accurate? If so, given that I haven't noticed anything with regard to clanks or erratic shifting, should I really seek to have this upgrade done? Does it make a discernable difference in performance or acceleration?

Yes there was an update in December but it is just software, so either build would work as both of them would be running the same software in every system. The update didn't change the performance aspect it was more for smoothness of the shifts, and to change the performance when really cold. It also was supposed to help with the 2nd to 1st downshift clunk or lunge that people had experienced. It was actually a very helpful update, IMO the best one so far.

I honestly haven't noticed the clunking, but then again I only have 250 miles on it at the moment. In any case, I figured I'd get ahead of it and just get it done now.

Just had the software update done on my June build Overland V6 and it took 2 hours at the dealership. Results are very good......shifts better from 2 to 1.... Even though it was never very bad after the first 1000 miles. Also had the update done on the 911 system . 4000 miles now....all systems go.

It would'nt surprise me if they use a dial up connection to perform the updates. But sometimes the updates do take a real long time. When I had my 2010 BMW M3, I once had to leave it overnight for some updates. They need to find a faster way to do the updates.

Lincoln would send me a USB flash drive in the mail for any required updates. It was a really nice perk. If you owned a Ford you would have to go to the dealer for the update. Hopefully I won't miss my Lincoln too much when I get my Summit.

Those were radio updates, not transmission and such updates. For the Uconnect radio's on these you can do it yourself through, just download to a usb and install it yourself.
