What does the fluid look like and smell like. Second do you have enough fluid in it. If the fluid is brown or has shiny metal pieces the trans is done. Do you have any codes? Will the truck move if you select manual 1st or 2nd gear?

Have you tried to see if the shifter arm underneath at the trans is moving? Maybe the nut came loose and is slipping on the cable?

Code 311 means you didn't hold the throttle down long enough during test. Remove the connector on the tranny and check for corrosion, clean and put dielectric grease on it and reconnect it.
