Scotty, I hooked up my scanner to my 2005 Jeep Grand Cherokee with 115,000 miles, and found a code. P0930. I don’t have a check engine light on though. The vehicle has an occasional hard shift. What does this code mean, and what would fix it? Thanks

pray it's just weak wiring and not internal transmission failure starting or a bad computer control unit for the transmission. That's part of the main computer and not only expensive, but super hard to correctly diagnose.
