GF's Edge has a button to kill TC, newer ones you hit the button to kill TC and hold it to kill SC (on certain models I think)
I wish there was a toggle switch to just leave TC turned off. I have never experienced anything with SC, it sounds like it might have merit but I am pretty sure I can do better on my own than TC can. The one time I experienced it it did far more harm than good.
It does more harm than good, it cuts power and you can't do anything at all. When I hit the gas I need the vehicle to move not cut power. Hit a mud hole with traction control & stability control turned on and you'll just sit there because the nannies cut power and you can't move.
Good to know at least with the fords you can disable it for those cases. I don't think its ever completely turned off, even in my tundra if you get crazy the nannies still will intervene.
I do notice that in 4WD they are less intrusive, and in 4Lo far less intrusive but they're still there.
For the most part I don't really need 4WD, a few times in the winter maybe but otherwise don't use it very often at all. Now this past winter was a totally different story, had my truck in 4WD for a solid month, most the 4WD has been used in any of my 4WD's LOL. However, most years we get snow its not enough to need 4WD and a 2WD will do just fine, its those odd years once in a great while that we get a good pounding with snow that makes having that 4WD option very handy LOL. But, in reality I'd get by with a base model 2WD ranger.
