ptscaddy1 Posted June 11, 2005 Report Share Posted June 11, 2005 code indicates PRND321 switch failure Does anyone know what this means any info would be appreciated. Link to comment Share on other sites More sharing options...
taiorlvb Posted June 12, 2005 Report Share Posted June 12, 2005 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!

ptscaddy1 Posted June 12, 2005 Author Report Share Posted June 12, 2005 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. Link to comment Share on other sites More sharing options...

Ranger Posted June 13, 2005 Report Share Posted June 13, 2005 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? Link to comment Share on other sites More sharing options...
