Re: Nuetral safety switch for 4L60E
 

I am digging into how to hook up my nss and back up as well.
I have a AAW harness and I think I have a van tilt column
I have not seen the switch on the column but need to look closer
Can I add the switch on the column if it is not there ?
or do I need to add the switch to the 4L60E
I also have a BP auto engine harness

Re: Nuetral safety switch for 4L60E
 

There are a couple of ways to add the NSS. If you have a van tilt, then it should have a switch on it, although the first van tilts didn't have them, but they are not that common. But, a van tilt has the switch too far up, so it will hit the brake pedal/column mount unless you shove the column all the way into the dash. You can cut a new slot in the column and the shift tube, but its harder to do with the column assembled, but I have seen it done, so I know it can be done, but definitely easier to do with the column taken apart, downside is it has to come all the way apart, which if you haven't done it before, can de a daunting task, but again, very doable with persistence.

The other way would be to to add the trans mounted switch and wire it through a starter relay, which is a little more wiring. Also, depends on what transmission you have. Cars have a short shift shaft that won't accept the trans mounted switch, so bear that in mind as well.

I do have the 4L60E truck trans, it had that switch on it and I bought a new one, but when I had the trans rebuilt the tranny place said I would not use it so I removed it, I guess he did not realize I would need it.
I bought the van column from Randy off here and he modified it to fit the truck, I just do not remember if it had the switch, it is mounted in the truck already and I will not be removing it.

Another option if you were to want a floor shifter. I went with an Art Carr Winters floor shifter with optional switches for reverse and nss. The switches are rated high enough that you don't need to wire a relay.

I found were the column switch goes but it is missing so I ordered a replacement switch.
on van columns it is on top of the column close to the firewall
