Howdy! Well, I got a rebuilt transmission installed on my 1994 Bonneville SSEi. Not cheap are they? Anyway, the car has always had (since I got it) a code showing the PRNDL error (which is the neutral safety switch). The trans shop told me that this problem (the neutral safety switch) probably caused the trans to burn up... huh? The trans always shifted fine and would NOT start in any other position other than park or neutral, even with the code. How could this error code, which concerns a safety switch in the console, cause the transmission to burn up? Doesn't make sense to me. I think they just wanted to replace the switch for me (extra $$$) but I don't know everything about computer controlled cars... The switch is $113 at the on-line auto parts store, probably more at a dealer. On the other had, not too hard to replace. Just the time consuming pain of removing the console cover and switch... Any help out there?

Okay... well not so simple as I thought. There are two neutral safety switches listed in the on-line parts stores.... They are almost identical, with two connectors at one end and the switch at the other. But one also has another wire bundle and connector coming out of it up near the switch. Anybody know which is the right one? Plus the parts description says "Att to Transm" which I think means "attached to transmission." In other GM cars that I've had the neutral safety switch was attached to a brace in the center console and switched by the shifter rod. Any trans experts out there?

Which one is it?

Not a tranny expert, done a lot of R&R. Couldnt tell you which it is. My experience with online parts stores data bases gives me fits. A lot of bad info in them, particularly with my GXP. The switch is a safety lock out and in no way can burn out your tranny. The thrown code could be an old one never reset. You can pull the ECM fuse or remove the battery post to reset. (Ignition off important) If the engine only starts in park or neutral, I wouldnt bother.

Thanks for the reply. I can reset using EFI Live and my laptop, code keeps popping back up, but you still can't start in anything but park or neutral. I agree with your assessment that it'* a simple lockout, but it'* very odd.
