Speedometer adjustment

[SandRailPilot]

I have a '92 K2500 Suburban 454, 4L80E with 35" tires, 6.5" of lift,and 4.56 gears. The speedometer currently reads about 80 when I'm doing 60. Is there a fix? The 4x4 places are stumped because it is electronic but apparently not programmable.

VSSB calibration

Don't know where this should go but since it comes down to electrical I put it here as a start. Mods feel free to put it wherever you think it would help the most. This info is from several sites plus notes I made when I did it for my sig truck. Different tire sizes make the Speedo wrong...

Thanks, guys. My soldering skills should be up to the dip switch solution. That way when I get my 37s I can re-adjust.
