1991 GMC R1500 Suburban Base 8Cyl5.7L - Transmissions & Drivetrains
Is there any fuses or relays that will cause the speedometer to not work?
I think it's on a pulsating unit. I have replaced the sensor in the transmission from a magnetic style to a pulsating gear to gear. I don't know if they are different or the same. I also don't know if it needs constant electricity or if it generates it's own. Please help. Thanks
