    I have a 2002 Santa Fe, 110K miles. Powertain warranty ending at 120K.

    About three months ago, I had to have the heads rebuilt on the Santa
    Fe. At that time, I also had the remainder of "major" service
    performed, including a tranny flush.
    delaying to shift into 1st and 2nd for the first minute or so after
    starting the car, regardless of how long it idle it. Sometimes it was
    less pronounced, but the recent cold weather has made it very obvious
    with very big (and scary clunks).

    A second problem I am having is that within the first 5 minutes or
    starting the car of stopping, the car will stall out at a traffic
    light. This was the more obvious problem initially, but I could not
    get the dealer to "recreate" it, and I had to ignore it for some time.

    Again, these problems (along with a radio that went from somewhat
    mediocre AM reception to less than zero when the engine is running ---
    some grounding or misplaced sheilding problem during the rebuild ???)
    have me less than pleased with my dealer.

    I'm trying to get this to them to sit overnight in the cold so they can
    test it first thing in the morning, but my luck, the cold snap is
    ending, and the problem is likely to be less obvious.

    Any suggestions or comments welcome.

    Since you had the transmission service done at the same time as the
    warranty head work, I'm presuming that the work was done at the dealer and
    the proper fluid (SPIII) was used. If not, you'll need to start by
    flushing the transmission and installing the proper fluid.

    Your transmission issue is most likely a wear issue with the transmission
    itself. Leaving the vehicle overnight for the dealer to test drive when
    cold is exactly the correct approach.

    Stalling out at stops tends to be an indicator that the vehicle's idle
    control system isn't working properly. Again, you're using the correct
    approach for the dealer to duplicate.

    Your AM reception issue may be a bit stickier. These vehicles had lousy
    reception from the factory. You could have a problem with the radio, the
    antenna in the left rear glass, or anywhere in the cable in between. It
    will probably require significant time and expense to find the cause.

    Dropping the vehicle off overnight for the dealer to check when cold is
    exactly the correct approach. If I were to guess, I'd suspect that you
    have a transmission wear issue and will need a transmission replacement.
    Flushing the transmission may have exacerbated an already present

    When diagnosing the stalling, I'd hope the dealer checked for any trouble
    codes. Many things that cause a vehicle to stall will store a trouble
    code. Beyond that, it's difficult to get a good idea what system may not
    be working properly without having testing equipment hooked to the vehicle
    when the problem is occurring.

    The Santa Fe's with antennas in the left rear window never had good AM
    reception. Additionally, this type issue may be difficult to diagnose.
    It could be in the antenna, the cable, or the radio.

    Thanks HyudaiTech!

    Of course, the cold weather pretty much passed, and the problem isn't
    as obvious, but I'm going to take it to them tommorow.

    I am well aware of the ATF fluid requirements. Frankly, I am
    concerned that when they flushed it, they may have used the wrong
    fluid, since they are one of these mega-delears and service all types
    of vehicles. (Speculation, but this dealer has hosed me once -- I won't
    let them touch my Sonata.)

    I've read reports that if the tranny is replaced under warranty,
    hyundai has them tested to check if "unauthorized" fluid was used. Is
    this true?

    If so, I can see me getting screwed because of THEIR error.
