I have an 18 Armada SL and love it, but I noticed that it holds the gears for longer then I'd like. It goes through the first 2 or 3 gears pretty quick and then for example, I'll be driving at 40 mph and my RPM's are at almost 2k. It won't shift into the next gear until I give it some gas and get up to almost 45 mph. I don't have the "tow mode" on and I'm not driving uphill or pulling anything. Does anyone else have something like that? I don't have a heavy foot and I always accelerate slowly. I'm curious if anyone can tell me at what speeds their transmission shifts from one gear to the next while driving the way I do.
