Anybody have any idea what would cause an intermittent CEL when accelerating in overdrive? It also show up when lugging between 30 and 40 MPH. It wont stay on, only shows up for a few seconds and seems to almost go away if I drive it in tow haul mode. It is generally accompanied by what feels like a transmission slip or a feeling like the torque converter unlocked for an instant. Once your at speed and cruising no issues at all. Fluids look good and at correct level. Just looking for ideas before I order a solenoid pack, Detent Plate, filters, and a Input and Output Speed Sensor Kit. Any help or ideas is appreciated.
