Imagine being a manufacturer and putting a factory option tune on your vehicle that puts the transmission at the theoretical torque threshold
https://www.motortrend.com/news/easter-jeep-safari-concept-turbo-engine-srt-tune/
Or there is the top comparison with the "weaker" transmission in the 2.0 and 3.6 Wrangler.Letās compare the 10R60 with 2.7 to the *Gold standard* in this segment, the 392 Wrangler with the 8HP75. Weāre going to use percentages because IMO that is a more accurate way to go about things.
470 Torque in the Wrangler with a transmission that has a torque rating of 553 Ft-Lbs puts the wrangler at 85% capacity.
415 Torque in the Bronco with a transmission that has a torque rating of 443 Ft-LBS puts it at 94% capacity.
Does that seem high? Sure. But when you realize that:
1. The 392 has WAY more horsepower which also puts a ton of strain on the transmission. The 392 has less favorable differential gearing which puts more strain on the driveline. And the 392 is designed to be launched on the street repeatedly which is about as hard as it gets for an off road vehicle.
2. The 10R60 is in use in the Explorer ST which has the EXACT same torque as the 2.7 Bronco, but also higher horsepower, tows more, is heavier, and also has less favorable differential gearing. Like the 392, the engineers have designed the ST to to withstand repeated 0-60 launches on the street which is about the toughest thing you can do to a transmission other than tow.
The transmission in the Bronco is living a pretty easy life unless youāre just beating the absolute piss out of it.
If I was this worried about transmission problems Iād get a cooler and be done with it. Heat is what really kills em, and that really doesnāt have much to do with the torque output but more how itās used. If youāre constantly maxed out towing with your Bronco through hills in the summer, yeah maybe Iād be a bit concerned. But for 99% of use cases the 10r60 will be just fine.
