I jumped in my truck to go to work and as I shifted into gear I noticed that the "D" on the gear position indicator was not orange and the truck would barley move. I shifted into reverse and that seems to still work. Other drive gears only let me move forward.... but not more than walking speed.

I checked the basics, Trans harness, linkage, Trans fluid all look good. I tried disconnecting the battery to do a hard resent hopping maybe just a computer glitch but no luck.
