Is it safe to switch tranny and suspension modes while driving?
.So what do I do first thing.

Again, dealer information no good

But I do need glasses now.

Note that it's not a warning about the transmission suffering any kind of damage but a warning that a sudden, unexpected gear change can result. I guess I wouldn't do it on an icy off ramp at high speed.
I will say, when switching in to dyno mode while at a light, I have had issues with the tranny wanting to switch out of say, 3rd gear...freaked me out and I stopped doing it after a couple of times. Now, I'll put it in dyno mode, and turn the car off. Of course, I don't do that at lights...
