Curious as to how you reserved the 2.7L? I reserved a Bronco but there was not anything there regarding selecting options.I personally reserved a 2.7 liter. I have driven many 2.3 liters in the Ranger and it is more than capable. Plenty of power and outstanding torque. I also however love the 2.7. I have driven many F150's with this engine. If you ask me, It is seriously underrated. It really boils down to personal choice. I'm getting older, not sure I want to shift any more, lol My opinion, you can't go wrong with either. I know that's not really an answer. If I were going to do some serious off-roading or over landing, I would probably go with a manual for the crawl gear ratio.
