I have 08 6.4 with sct tunes by Eric. About 3 weeks ago I filled with diesel, not long after truck went crazy, wouldn't shift, sputtering no power just crazy. Take to stick Samething. Dealership said it was tcm and solonoid. Replaced, got truck back kept getting wrench but it was saying oil an coolant temps out of range, I thought well it's the new flash doing it, called dealer they said its prob just bad sencor, a week later I take tuner to tow tune so I can haul my bobcat.. Truck went about a mile Samething, want shift, sputter, stuck in gears loss of power. Dealer said another tcm gone, now the have it in but truck still want run rt. they say it throws codes everywhere, they finally get them cleared, take truck for spin it does Samething.. They think it's a wire somewhere but they have no clue wher.
