I soldered a stepper in my buddies 03 Silverado for his trans temp gauge. works flawless. Few weeks later I tried in my 05 and it didn't work, soldered 2 different motors in and still nothing. No pictures but the solder points look good. A couple months later another friend tried in his 06 vmax and his doesn't work either. Is it possible all these stepper motors are bad? someone told me the cluster might have to be programmed for it. Any info would be appreciated. Here's a picture of mine before and after. just sits at 100
