I went to leave my house this morning, and the truck would not shift into gear. I placed it in reverse, and the display on the dash said "inhibited place in N to reset". I place it in N and everything reset. I backed the truck out of the garage and shifted the truck into drive. It did the exact same thing. This time I could not get the truck to say in gear. It kept saying shift to N to reset. I didn't have time this morning to check the transmission fluid, but does anybody have any ideas what is going on?
