No clunking noises coming from the transmission when you shift? It may just be wiring issues with the harness in the console itself, the reason why I say this is because I just recently converted my 2004 from a column shifter to a center console shifter and the wiring is very delicate. Pop open the center console and take a look inside, perhaps the coil solenoid has gone bad which is not allowing you to shift the truck. The design between the column and console shifters are practically identical, and it could very well be an electrical issue more than a mechanical issue inside the transmission itself.
