Digital display of mph not showing. Only a round gear type symbol

Hello, this indicates an issue with electronic transmission data -- possibly due to speed sensor circuit concerns. Hands on testing is needed. You may have some manufacturer's warranty left -- some powertrain components have 5 year / 60,000 mile coverage. I don't know the age or mileage of your vehicle, nor what has failed, but it warrants sharing. www.repairpal.com/repair-shops
