Hello....If I am not mistaken, this code is telling you that the shifter switch is not working properly. PRND321 = P-park,R-reverse,N-neutral,D-drive,3-low3,2-low2,1-low1. You might want to disconnect it, clean the ends, and reconnect it. I hope this helps you out!

Thanks, for the info. Do you know where this switch is located & how difficult it would be to replace, if I had to replace. Saw on the archives of another board that it is located on top of the trans. any additional info would be a great help. thanks.

Isn't there a special preceedure and/or tool used to properly install the PRNDL switch? As I recall it has to be aligned with some sore of aligment tool or drill bit. Or was that just on the 4.9?
