    When you clear a code, the car is cooled into thinking the car is fixed.
    This will last until the car figures out it is not fixed.

    The codes you have can be serious since they are related to the transmission.

    What conditions lead to the car getting these codes?

    How long do the codes remain off when you clear them (short time?Long time?)
