Why I switched to the 2.3L over the 2.7L...

[ColbyFromBama]

The 2.7 is an extremely powerful engine. The twin turbos really add an incredible amount of torque. Unfortunately, I think the 2.7 has too much torque for the 10R60 transmission the Bronco is getting. In fact, the 10R60 transmission only has a torque rating slightly above what the stock 2.7 puts out. Which means if you get the 2.7, you’ll have a lot of wear and tear on your Bronco transmission, especially if you add a tune.

I’m more worried about the longevity of my Bronco, than immediate power. And I don’t feel like upgrading my transmission. So I’m sticking with the 2.3L. And I’ll add a tune later. I’ve driven both engines, and you can barely tell the difference unless you’re on a steep hill.

If Ford offered the 10R80 transmission in the Bronco, I’d without a doubt upgrade to the 2.7. Even the Ranger comes standard with the 10R80, that allows for more torque than the Bronco.

Might as well get the base with 16 inch wheels. Don’t want to stress that tranny too much

It'll be fine. If the Aviator and Explorer ST with the 10R60 can take the power of the 3.0T than your Bronco will be fine.

Side note the 2.3 has bigger cylinders, i aint paying 50k for a sewing machine!

Nah. The 4.7 gearing on Sasquatch is what makes all the difference. Doesn’t stress the transmission at all. If you drove one, you’d know. It’s the massive amounts of torque that stress the 10R60.

They actually can’t handle the power though...

“Consumer Reports was one of the first outlets to get a 2020 Ford Explorer and take it out for a test drive. They noticed right away that driving the Ford Explorer in suburban settings can be somewhat of a problem. The 2020 Ford Explorer has an issue with lurching and pulling while you're driving. There are also some very rough shifts from first gear to second gear after you experienced these lurches and pulls which tend to happen when you stop at stop signs and traffic lights. Additionally, the transition from 2nd to 3rd gear has also proven to be problematic.

Another issue that test drivers noticed with the Ford Explorer’s transmission for the 2020 model year was that it will hold on to a gear longer than it needs to. Typically, when you're driving with an automatic transmission once your engine reaches the appropriate RPM's for a gear shift to take place it will do so. That's essentially the whole purpose of an automatic transmission. It recognizes that your vehicle is up to the required speed and assessing the shifting gears. However, the transmission in this model year of the Explorer stays in a lower gear longer than it should and in turn causes some serious noise to come from the engine as a result.”

Ford isn't going to put a transmission in the Bronco that you are going to explode off road. They've done proper durability testing. There's a reason why 10R60 was okayed for 2.7TT and the 7-speed manual was not.

Nobody said it’s going to explode immediately. We are saying that the 2.7 will wear out the 10R60 transmission way faster than the 2.3 will. That’s all.

CR says that about a lot of transmissions. And some of the programming of the 10R transmission (both 60 and 80) has been not good. I put a few thousand miles on an Explorer ST recently and I didn't have any issues. Neither did my wife.

There's been a lot of people complaining about the 10R80 in the Ranger too. And that just has the 2.3T. Chances are, if you look up "X automatic transmission", there will be people complaining about it online.

 

[Tdifonzo]

Even if everything you said is true (it's not) how often are you actually using 100% of the engine's torque? It will be fine.

 

[lobbs611]

I've not been able to confirm yet but I've seen some rumblings that the 10R60 and 10R80 as almost identical with some minor internal differences. The 10R60 seems to be very difficult to track down any real info on.

There is no empirical evidence to suggest that. I guess I could ask my Ford buddy that has access to the data if there are more failures on Explorer ST transmissions vs Explorer 2.3 transmissions. It will certainly vary by owner.
