Is there any difference in speedometer reading if you are automatic or manual

[JohnM]

Thank you for the replies sirs. Btw, where do this cables/wirings of speedo attached? Nalilito kasi ako sa tinatawag nilang gearbox ba yun? May problema po kasi yung speedo namin, di pumapalo yung needle niya, ok naman speed sensor, sa connection sa dashboard na po kaya yung problema nito?

There is a cable that runs from your speedo to a gear inside the gearbox/transmission. Baka putol na.
