Running at 60 miles an hour Truck slips and engine light comes on. you shut it off and start it 3 or 4 times and then the engine light goes back off and shifts normally

Hello, don't be too sure it's an electrical problem. When the powertrain control module sees an issue somewhere, it will alert you via warning lights. And eventually it will not allow the vehicle to run as designed until the concern is repaired, because further damage is being prevented, and a safety concern may be present while the problem is occurring. This problem may totally be an internal mechanical transmission concern that happens intermittently but often enough to set the check engine light. Any way you look at it, diagnostic testing is needed to find out what's going on. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
