    2010 SRT8 CEL P1731 and P0730

    Hello everyone,
    Got these codes in my car.
    Happened out of no where when I was driving and the car wouldn't go past 28 mph, turned it off and turned it back on same thing. The car would not move out of a dig if it was inclined.
    Parked it and came back after 2 hours and it was working fine, I can go faster, but It still feels the shifting is not normal.

    The car also has C2205 and C121C but those codes have existed for a while now I believe.

    Did a transmission flush and changed filter last summer and I've put on it over 15000 so far.

    Do I need new trans?

    First check the fluid level- properly. Second check the electrical harness connection. These things are very sensitive to proper fluid level. Water in the connector can cause problems too.
