4L80e no speedo Hey guys... Got a Jakes 4L80 stage 5 installed in the car and now have no speedo. I followed all instructions about repinning wires and all that, but have no speed signal. I'm using the 4l60 tune with the relay to reverse the 2-3 solinoid also. It will shift and drive normally, but no speedo or lockup. Any thoughts of what it could be?

i cant tell if it shifts normally or not.... i think i feel a shift in there when i keep it in drive, but not sure. i had the scanner going on it, and it showed no speed though HP tuners either. not sure where to watch for it
It's difficult/impossible to help diagnose without accurate information.
Be sure the wiring is properly hooked up to the rear speed sensor. It should use the existing wiring from the previous transmission for the VSS.
