    FINALLY! I have a working speedometer and transmission temperature gauge. Only took about a hundred hours of trouble shooting and rebuilding, as well as several hundred dollars :angry94:

    My advice, if you have pre 2002 Tahoe, buy one and annotate your odometer. Don't try to make odometer right. Had I done that, it would have cost me $80 and about 5 minutes of work :eek:

    You're not alone in this oversight. I just realized I was trying to do the same 100 to 120 swap. There has to be some way to re-calibrate to get an accurate speedometer.

    Wow, that realization must have made you slap your forehead and say duh! So much work over a simple mistake. I’m glad I’m not the only one to do things like that.

    Yeah not sure it is the best but in the computer you can adjust the VSS calibration... however the computer will have the wrong speed while your dash has the correct. I think if you have the hardware / circuit board that came with the face then it should work without messing with the computer.
