On Vehicle Service; Speedometer Replacement - GMC G Service Manual

SPEEDOMETER REPLACEMENT

Servicing of the speedometer assembly should only be
performed by trained technicians having the proper test
equipment.
When replacing a speedometer or odometer assembly,
the law requires the odometer reading of the replacement
unit to be set to register the same mileage as the prior
odometer. If the same mileage cannot be set, the law
requires the replacement odometer be set to zero and a
label be installed on the driver's door frame to show the
previous odometer reading and the date of replacement.
