my old truck run's awsome for about an hour then the other day the overdrive light started flashing and the truck started missing and shaking it felt like there was a small tingling when i was touching sertain things maby im crazy about that part. then on the way home from work it died going down a hill when i let of the fuel. its got a new cam sensor so not worried about that

If the OD light flashes, the trans threw a problem code. Sometimes my '97 throws a code becasue the torque convertor slips a tiny bit. It will shift VERY HARD until I reset the code. I'd start by having the code read and see what it is.
