GuyTelefunken Posted January 26, 2006 Share Posted January 26, 2006 There is a problem with your transmission position switch, aka. park neutral safety switch. Either the bolt that mounts it to the side of the transmision has come loose (unlikely) or the switch is on the way out. You will most likely find code P1780 in the computer, relating to more than one position selected simultaneously. If it is loose, adjusting it's position and tightening the bolt should correct your problem. You should clear the code to turn off the MIL (Multifunction Indicator Lamp, check engine) when you are done. Otherwise, replace and align. Note: You may have to remove the exhaust pipe to access the switch. :-) PNP_Switch_Adjustment.pdf Quote Link to comment Share on other sites More sharing options...
