    It's weird, last night my cel came on and transmission shuttered in between shifts. Neither of these two things have ever happened before on this car. Today got code (PO742) in the morning from autozone, and forgot to have them reset the cel. Drove the car 3 more times today and the cel was on every time and the transmission has worked fine all day (no shutter) but just got back from a 10 min drive and the cel is gone. Did the car fix the issue and turn the cel off?
    Figured I'd share this

    Got the same code in mine.. along with 3 others. It comes and goes. Has something to do with the TCC solenoid. BillBoost gave me a great link for some more info on the code.
