The 3g 6MTX Under Extremes
Here's an interesting observation....
I'm property shopping right now, including in some areas with rather "extreme" access. As in on top of a ridge, with a switchback-laden and very steep driveway. Many of these, if not most, are gravel "roads" (if you can call them that.)
The 6MTX (I have a 2016 Sport) has an interesting limiting factor in these conditions. First, all front-drive vehicles have a nasty characteristic in that weight transfer is to the rear under acceleration and on a steep grade with loose substrate this is very bad to start with. In other words your ultimate climbing capacity in such, assuming no ruts that cause you to high center on something, is mostly about the traction loss from that effective weight shift. You do much better with rear-wheel drive in such conditions.
Anyway, the 6 MTX has a second limiting factor -- even with TCS intentionally selected OFF if you get into any sort of wheelspin event (even a light one) under such conditions the ECU will shut down power delivery even though you've told the system not to do that. Note that you CANNOT slip the clutch in such an extreme hill-climbing situation to try to get further into the torque band; you'll light the clutch on fire if you do that, so you have to make the climb in first gear with the clutch all the way out (and locked) and keep your vehicle speed high enough to remain reasonably within the torque band of the engine.
This was a quite-extreme situation but I wanted to know if I could get up that driveway in my "6." The answer was "no"; I was forced to back down from about halfway up one specific section. With an automatic I might have had different results due to the torque converter (if you don't overheat it, which you might), but in first gear with the MTX it just wasn't happening.
This was a ridiculously extreme set of conditions but it was a useful piece of knowledge to have -- I now know where to start worrying about that limit in this vehicle.
