    Default trans program error

    that comes as a safety measure when something is wrong. The system goes into emergency mode.
    It must not absolutely be the transmission or the module of the trans, but it can also be the trans.
    Some simple questions first:
    Have you checked the battery and the charging voltage? If that is too low, the system reacts very sensitive and it goes into limpmode. If the system is abt. 90 seconds below 11..6V: limpmode
    Do you see the gear selection indicated in the dash? If not, the gear selector switch under the console near the handle for the trans might need cleaning, in such case the system does not know which gear is selected.
    Also the ABS system might be defective causing this.

    The easiest is you visit a dealer or a ship with a code reader system which can make a diagnosis. He just will plug the connector into your diagnosis socket under the hood and it will read the faults.
    Or do a stomp test and see what you can find. Stomp test is only possible on cars produced according to US specifications.
    If you do not know the stomp test, click on my website below where it is described.
    You might also try a reset as shown on my website.
    But first of all check battery and charging voltage and the other things mentioned above.
    Let us know the result and then we will try to figure out the next step.

    Have no idea where you could download a scanned copy of the B.
