Recalibrate electric speedo 700R4
Just changed rear gears from 3.08 to 3.73. I have a 700r4 trans with electric speedo in my 1990 GMC Sierra. My speedo is now way off. How do you re-calibrate? This has a magnetic sensor rather then the gears like the earlier 700R4"s. Any help would be greatly appreciated.- Roger Bentley
