Hyundai Elantra Transmission Questions

    Backy, What trouble did you have with the clutch in your Elantra?
  • backybacky Twin CitiesPosts: 18,628
    On my '01 Elantra, my son and wife abused it to the point where it broke. :cry: Before that, there was a squeak when depressing the clutch pedal, which was fixed under warranty with new bushings (I think there's a TSB about that).

    I prefer a stick verses an automatic. My automatic in my 2002 Hyundai Sonata did not want to shift into 3rd and sometimes missed 4th and went straight to OD. Changed the fluid was recommended by the dealer and still did it. Between the Elantra and the vehicle they copied the Toyota Corolla. I bought a Corolla due to the transmission and the rear seat legroom.

    FYI, 4th is overdrive on the 2002 Sonata automatic.

    we had alot of problems with our 2003 sonata. It would get locked into second. The dealer finally had to replace the transmission. It had less than 2,000 miles. after it was replaced it still did not seem to be right. we did not trust it so we traded it for our 2005 elantra gt manual transmission which we love.

    I own an 07 Elantra SE 5-speed. When backing up, actually coasting backwards down my driveway with the car in reverse and the clutch fully depressed. I can hear a subtle growling sound like you would expect if you were actually backing up with the clutch fully engaged and accelerating. I don't think this is normal. Also, I noticed the speedometer is actually registering a speed while I'm travelling in reverse. Not much but the speedometer is definitely not on zero! Anyone ever seen this? Time for a trip to the dealer for some repairs?

    You're asking the wrong person. It was ppcdc30, in response to backy that said, "With the automatic problems I have had in the past I think I am going with the sportier 5 speed."

    My new 2007 elantra has already had a new transmission put into it, and unfortunately it's still having problems. When I drive around 35mph it starts making a droning noise and has a slight vibration to it. Since the new trans was put in it now does it when I'm only doing 25mph also. Dealer told me it was the torque converter, so they put in whole new transmission. Still the same but a little quieter. Test drove a brand new one (5 miles on it) and it did the exact same thing---was told this is a "characteristic of the new engine" and that it was doing "no harm" to the engine. Trying to get them to write up a TSB on this issue seeing as I was told I'm not the only one experiencing this problem. Just wanted to see if anyone has experienced this similiar situation and if they have got it resolved?

    no problems with the transmission.I just find that it lugs a bit, cause I don;t think it is geared as well as the '99 Elantra.I am very light on the pedal, so perhaps should expect this but the '99 is better.
  • bhmr59bhmr59 Posts: 1,598
    If you're driving really slow for top gear, try using the Shiftronic, or goose the pedal just a little. Either one won't cost you anything noticable in MPG.

    Your new car is probably designed to be more fuel efficient for normal driving. That doesn't mean that top gear is always your best choice, i.e. lugging.
  • skybelouskybelou Posts: 2
    Has anyone else with a new 2007 automatic Hyundai Elantra experienced their car lugging while driving around 35 - 40 mph???
  • backybacky Twin CitiesPosts: 18,628
    If you are in fourth gear at 35, it could be lugging. What are the RPMs at that speed? I've found if I take my '04 Elantra AT below about 1400 RPMs, it starts lugging a bit unless I am coasting along on level ground or a downgrade. But the '07 may have different gearing, since it's more fuel efficient than the '04.
  • harlqnharlqn Posts: 18
    Mine does lug about that speed, but it's also at low RPM (I don't recall the number off-hand), so it's not unexpected. If I'm going to be going that speed for quite a distance, I force it to stay in 3rd (AT). Otherwise, I just increase the distance ahead of me so I can coast/accel/coast/accel

    Hi, I just bought a 2004 Elantra for my son and we noticed that when accelerating the cars RPMs will jump and the car would do a hesitation. The dealership where we bought the car from did some sort of computer adjustment so that the tranny can "relearn" itself. Still same problem. Does anyone recognize this annoyance?
  • doohickiedoohickie Posts: 949
    Although there is some adaptive learning involved (or so I hear), if the RPMs are jumping between gears it sounds like a tranny problem (assuming it's an AT). If it *is* an AT, know that ONLY SP-III AT fluid (available at Hyundai, Kia, Mitsubishi and maybe Chrystler dealers) should be used in the AT. If the AT was flushed with something else, this could be the start of a tranny breakdown. If you think maybe it has the wrong fluid, you might want to take it to a dealer and have them check it and, if necessary, flush it with SP-III to prevent real tranny damage.

    If it's a manual and the RPMs don't like to drop when the clutch is depressed, that is a known issue and if there isn't a software fix the dealer can do, I know of a simple modification to the Idle Air Control Valve that prevents the RPMs from hanging when you pull your foot off the gas. If your son has a MT you're interested in the mod, let me know. (It's basically making a restrictor plate for the IAC valve to keep it from holding the RPMs high. Hyundai does this because letting the RPMs drop too quickly hurts emissions.)

    "when accelerating the cars RPMs will jump and the car would do a hesitation."

    Assuming it is an automatic, isn't this the "shift flare" problem that a lot of Elantras have experienced? I think there is a TSB for this...I know mine had it. I think it was 2nd to 3rd gear shift where the RPMs would flare up. My '02 started doing this right after we bought it (new), and I had the TSB performed on it (which I think was a software adjustment). It got better, but still occasionally happens from time to time. I now have 92,000 miles on the car, and get the transmission fluid plushed every 30,000 miles.
  • carsnakecarsnake Posts: 4
    Thanks! Yes this is an automatic. I think that you are correct it does do this between 2nd and 3rd. Can you tell me what a TSB is? I am bringing the car back to the dealer that I bought the car from and I want to know what I am talking about.
  • 1racefan1racefan Posts: 932
    Here is the info for the TSB, per this (Edmunds) website...

    Bulletin# 0240001 from January 2002. NHTSA item # 628956

    Summary - Some vehicles may experience a 2-3 shift flare condition (engine speed increases during shift).

    Maybe doohickie can chime in, and show you how to look up on the "webtech" site, and see exactly what the dealer is supposed to do in order to correct this. Also, make a note that the TSB I am referencing is for 2002 models, but it sounds like this is the problem you are experiencing.

    Like I said earlier, my car started doing this right after I bought it (brand new), and we did have the TSB performed on it. The condtion pretty much went away, but it will still do it about once every 2-3 months, and I now have 92,000 miles on the car with the original transmission.

    P.S. - TSB = Technical Service Bulletin. These are issued by the manufacturer, and sent to dealers. They are essentially little bulletins the manufacturer sends to the dealer regarding problems that seem to be "commonly seen" in a particular model. In addition to notifying the dealer of the problem, they instruct the dealer how to fix it.

    I also used the abbreviation NHTSA in my post. This is the National Highway Traffic Safety Administration in case you were wondering.
  • carsnakecarsnake Posts: 4
    Thanks again! I found a tsb that was for the 2004 models. The bulletin I see is 0440012, sequence 10009779. It describes it as "Automatic transaxle harsh and/or delayed shifts. to include 2005 elantra". So basically, I can bring this car to my local dealership to fix? because the dealership where I bought this car is far away.
  • 1racefan1racefan Posts: 932
    I would take both, BECAUSE.....

    What you described (an increase in RPMs) is a "flare". The TSB you are mentioning does not specifically mention the "flare" in RPMs between gears.

    Any Hyundai dealer should be able to handle the repair. Just a suggestion - I wouldn't go up to the service guy and specifically say, "This TSB needs to be performed to my car." I would instead say, "My car is doing such and such, and through my research I have discovered these 2 TSBs. Could you please see if they are applicable to this situation?"

    Going this route, you aren't coming off as being too arrogant (or acting more knowledgable than the service guy), but yet you will have given him enough info to know that you somewhat know what you are talking about.

    PLEASE - let us know how things work out for you. I have found the guys taht post regularly on this Elantra forum (doohickie, backie, jlflemmons, snakeweasel, and a few others), to be extremely helpful. These guys are very quick to help solve a problem, or offer a how to, which epitimizes why message boards like this exist.
