2001 Elantra automatic transmission flare/slip

Discussion in 'Hyundai Elantra / Lantra' started by Bruce Guenter, Nov 28, 2006.

  1. Hi.

    My 2001 Elantra has had its automatic transmission replaced, and now it
    slipping/flaring intermittently when shifting from second to third.
    When I discussed it with the dealer, they indicated that the
    transmission controller may need to learn the new transmission and to
    give it some time.

    My question is, how long should it take the computer to "learn" the new
    transmission, and can this do permanent damage to it?

    Thanks.

    I'm sure that what the dealer really meant to tell you was:
    "Resetting the adaptive values and relearning the values for the new
    transmission, which would involve a brief test drive, is part of the
    service procedure for replacing the transmission. I'm sorry we didn't do
    this when we had your vehicle in for service. We can do it right now to
    rectify the situation if you'd like. It should take about 30 to 60
    minutes."

    Sorry for the sarcasm. It really troubles me when someone does a crappy
    job and then makes like it's not their responsibility to fix it. Once
    cleared, the values should reset after several 1-2-3-4 and 4-3-2-1 shifts
    after the vehicle reaches operating temperature. If they never cleared
    the old values, it could take quite a while. And yes, the shift flare is
    slipping the clutches in the transmission and is wearing them.

    It's likely that the real issue is that your transmission computer needs
    to be reprogrammed. There's a technical service bulletin specifically
    referring to the condition you describe. It's bulletin number 02-40-001.
    If you don't have one, register for a free account at www.hmaservice.com
    and print out the bulletin. Take the bulletin to the dealer and ask them
    why it is they don't know about it.

    And while you're at it, ask them why it seems to be your responsibility to
    reset the adaptive values on the transmission when Hyundai reimburses them
    for this as part of the labor operation to replace the transmission. TSB
    06-40-005 should convince them you're correct on this matter, too.

    The TCM is covered only for five years and 60,000 miles, so its
    reprogramming is your responsibility. But in light of the troubles you've
    had with this dealer's BS, you may be able to convince a manager to do this
    for you at no charge.

  3. I wish.
    Sadly, this is not the first time I have been unhappy with this dealer's
    service department, nor are we the first people unhappy with them
    (coincidentally, or not, also an automatic transmission problem).
    As far as I understand, disconnecting the battery for several seconds
    should clear these values. I have done this (to reset the ECU settings)
    and the flare did not improve, even after driving for a while.
    My car's VIN doesn't match the range listed in that TSB.

    Thank you for your time.

    Sorry about the reprogramming, Bruce. I just glanced through the TSB and
    assumed it would apply to all 2001s.

    The applicable TSB then would be 03-40-015. I didn't mention it earlier
    because it specifically mentions first doing the reprogramming which I
    assumed would apply to your car.

    According to the TSB, if the fluid is full, the reprogramming doesn't
    apply, the fluid temperature sensor is giving proper readings, and the
    adaptive learning has been completed (requires ATF temp of 122F or higher
    on your car), then the transaxle should be replaced to correct a 2 --> 3
    shift flare.
