    After driving on the highway for some time above 55mph(80km/h) the up-
    arrow on my dashboard will suddenly begin to flash; at the same time,
    the drive mode selector lights on the gear goes berserk. The gear
    shifts fine without any problem. I got the car scanned at a local
    workshop and it came with error code PO740.

    Any suggestions on what the problem could be?

    P0740 indicates torque convertor lockup malfunction. This means the
    lockup clutch inside the torque convertor is slipping - I would suggest
    a complete transmission fluid flush if it is not pink like it should be.

    Replace tt with t (twice!) and remove parentheses to email me directly.
    (But I check the newsgroup more often than this email address.)
