Cant figure it out but since my 4L80e swap I've been catching snags. long story short Nic tells me that my PRNDL (or Neutral Safety) Switch is telling the truck that its constantly in gear (or park/neutral, I dont remember, either way its not right). So I got my shift cable adjusted and everything with the shifter is right. The PRNDL all reads correctly except park has never lit up since this PRNDL switch was put in neutral lights up then goes right out. I think its something wrong with the PRNDL switch since its never worked right since install. Just so Im not chasing my *** does it sound like I need a new one? and is there a difference between the 60e and 80e switches?

 

I used my 2000 switch on my 2004 4L80E... everynow and then my reverse lights dont come on. move the shifter a lil and they work... Thats the only problem i have.
Take the connectors off and plug them back in.

 

hmm well thats one of my problems, when I did the swap I couldnt completely disconnect it, cracked the housing and only got one connector off. I think it may need to be adjusted differently for the 80e?? but other than that I think it might be junk since its never lit up park anyway?

anyway, I think Im gonna just order the new PRNDL switch on ebay for like $20 when I order the injectors and pray it fixes it

thanks for the advise tho Nonnie

 

anytime..
you can adjust it, i just havent gotten around to it yet.
my connectors were a pain in the butt to get off! then the dog chewed some of the wires and made it even worse tryin to get everything back right..

 

So the switch is bad?Thats what I was thinking.Seen itmany times

 

It's very possible it is. Turned out my idling in gear problem was the segment swap was ineffective... Thanks HPT! Anyway changed the OS and got it straight

Still think the switch is bad so y not order one for 20 bux

 

let us know how it turns out..

 

Definitely. Getting exhaust tomorrow so it'll be about a week cuz Ill order it with the injectors
