Or smart, as you avoid complaints about it "skipping a gear" or some other design intent feature when it is acting perfectly normal. Or perhaps the space on the IP was better used for something else? Regardless, if the transmission malfunctions enough to miss a gear that was intended, it will set a code. If you have a driveablity complaint, you are better off demonstrating it to the dealer, than describing it and having them go hunt for it anyway. I had this once on a Taurus. I said the engine made a noise. They said it didn't. I showed it to them. Then they bought me a new engine.
I was in a Jeep last week and it was the same thing. Gear only displays if you are in some sort of manual mode. Paddles, rocker switch etc.
