Very nice. Doesn't that shifter feel so much nicer in your hand than the nbs round one?

I think i asked this before to no avail... I have seen a few listed that say "for 6l80e vehicles only" or something... Is there really a difference?

I was just trying to give my best guess. Only thing I could think off that could have some affect where the transmission is concerned.

Yeah, I just didn't even think there could be a difference. The button just turns the computer to a different tune. It's just a momentary switch. I wondered if the way it hooked to the column could be different, like there's an extra position or something...

There's a + - button that's for manual shifting of the 6l80 that we just don't use. The plug is different since there's 2 black wires for that button plus 2 white wires for the tow/haul button, so it's a 4-wire plug. Either cut the plug off the old shifter and wire it to the white wires of the new shifter so it plugs right into the truck or wire the white wires direct with no plug. The black wires don't get used. And the + - button has a circuit in the shifter with resistors in it so the 6l80 knows if you're hitting the + or - so if you want to use that button for something else you'll have to open up the shifter and mod it.

The nnbs base model one only has 2 wires like the nbs so trial and error is the same since mark already figured out the 4 wire plug lol.
I call it the base model cause I figure the +/- version is an upgrade option.
I actually have 2, one with +/- one without. But not an esky one. Either way the nnbs look and feel better than the nbs imo20170720_160614.jpg

Edit: my wires were black , blue, pink , and purple . I hooked up the black and blue for the tow haul 20170812_052338.jpg
