Need advice - 2001 Elantra GT - auto transmission only uses 2nd and 3rd gear -

Discussion in 'Hyundai Elantra / Lantra' started by Stanley P. Pickens, Sep 2, 2007.

  1. My tranny operates normally when the car is first driven for 20 mins to an
    hour. Normally it will then be parked for 3-4 hours. When I start driving
    then, the check engine light will come on soon after starting to move and
    only 2nd and 3rd gears are available.

    Dealer mechanic says it needs an "output sensor" to make it shift

    This happened breifly @ 6 months ago and the "input sensor" was installed
    to fix it and it ran fine for 3-4 months.

    Does this sound correct?

    I am hoping to have the part installed also so the cruise control will
    work again (the part is in but it has taken @ 9 months to get it - I was
    told national back order ).

  2. I had both the transmission input and output sensors break on my '01
    Elantra GLS, the output sensor at 80k and the input sensor at 100k.
    That is definitely what it does (the transmission drops into a "fail
    safe" mode so that no matter how fast you're driving it's not as
    likely to damage the engine), although once it went bad, it would fail
    right away. It was the freakiest thing the first time it happened.

    I can't image having to wait 6 months to get the part, that's just
    insane. It must have ruined your fuel economy!

    Thankfully, if you can turn a socket wrench, it is a really easy
    repair to do yourself (which, combined with the free online service
    manual at is a huge part of why I like Hyundai).
    You just gotta remove the air intake box, and it's sitting right
    there. (You can also then see that, when Hyundai got rid of the
    external transmission fluid filter, they left much of the casting for
    where it would be mounted in place. I find that kind of cute :) )

    Everything sounds correct except the 9 months for national back-order.
    We've had them in stock at my place of employment continuously for about
    the last 3 years.

  4. I'm sorry I wasn't clear. The part for the cruice control is here. The
    mech just wanted to get the part in for the tranny so that both jobs could
    be done at the same time thus saving me a trip.

    That was my understanding, and I was referring to the output speed sensor
    as being constantly in stock.

    Is there a site to get the european version. I an in Cyprus and have a
    SIngapore import, would love to get the manual for it.

    I don't know of any. This vehicle is global, so you'll probably be able to
    use the USA service information for a fair amount of things. These are the
    typical differences I've seen between U.S. and non-U.S. vehciles:
    -- Engine
    -- Fuel management system
    -- Creature-comfort options.

    The primary thing to keep in mind is to pay attention. If your car
    doesn't seem to be like what the service manual describes, you should
    probably presume this is one of the differences.

  9. You have to watch that even repairing the "correct" vehicle. I kind of
    wish I had cataloged the discrepancies I've found :)
