NSS not working

So opposite problem of most - when I did my lq4 swap a while back, everything works but the nss seemed to be bypassed. I can start the truck In any gear, doesnít need to be in park. Not fun when you didnít quite have the loose shifter in park and lurch forward when you turn the key!! What did I screw up? Been a while and was staring at the wiring schematic but Iím not sure where I went wrong

Re: NSS not working

Probably recommend starting with what yr truck your swap is in.. can say from experience typing what your saying makes perfect sense to you but to others is nothing but ???
But I'd say fix the loose shifter and figure out the trucks factory safety neutral switch as a ls swap has nothing to do with how it starts in gear with the trucks factory starter wire

Re: NSS not working

1970. Everything was fine prior to putting in the 02 LQ4 so just assumed it was something I did. To clarify the shifter itís just the shifter shaft on the pin thatís loose not the shifter mechanism. Either way Iíll dig into that area first thanks

Re: NSS not working

Switch can go bad too, connectors bumped and knocked loose too

Question Re: NSS not working

Did you use the transmission that was in the truck before the swap are a new over drive transmission? The NSS has to get signal from the transmission to know what gear it's in. Weather it's manually are electronic.

Get out and drive the truck this summer and have some fun!
It sucks not being able to hear!

LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
