Car runs perfect until it shifts into overdrive. Then will cut off and will NOT re-start unless the battery is disconnected (wiping the ECM, od course) It will cut off at 46MPH, 55. And 70MPH. We have eliminated, ECM, Fuel Pump, we have a perfectly tuned and running car here. UNTIL it goes OD! Tranny shop says its not Transmission? There are NO trouble codes present nor pending. Although, once we had a Traction Contol Code briefly. Has anyone "EVER" even heard of this?
have the same problem?
