{QUOTE=firebladeJJ;5521639]@Alanis001 how did you handle your Park/Neutral Safety box? Mine does not fit to the side of the 6l80. Run new wires or tap?[/QUOTE]
I actually took it off the 4l60 n left it plugged in and it just sits on top of the 6l80. I programmed the pcm to manual. I have not tried to unplug it and see if it will start with out it.

looking at the diagnostics for the speed sensor on the 6l80, it looks like it generates a 8.3-9.3V signal and the one on the GMT800 for the speed signal is something like a 5V signal.
on my truck when i had the sensor unplugged at the T56, it would give a rear ABS DTC
I dont know if that helps any or what to do with that information but there it is.

so just spliced in the speed output wire on pin 41 of the 2650 module into the cluster speed wire and for me adjusted in the software ppm to 1000 and got the right speed showing. Only thing the abs n park brake light still on so going to try and splice that into the pcm speed to feed to the abs module.

What laptop do you have? Have you updated your drivers?
