"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.

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.

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.

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.

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.

Many thanks for the help, I'm sure without this knowledge I would have gone through a very frustrating process. Hopefully, this is the trick. I will definitely follow your instructions and let you all know what happens.

Transmission Flare and Check Engine Light by dc_newbie

Similar to problems that I'm reading here. My 2001 Elantra Automatic has started skipping or flaring on some gear changes. You feel the skip and then the rpm goes higher than normal immediately and the check engine light comes on. When I stop and restart the problem goes away and the transmission engages normally and no Check Engine light. This happens often, but more often when it is above 80 degrees outside.
 
Anyone had this happen to them? I have an appointment with the delare for Tuesday and am preparing. Total mileage on my car is 49K, so I'm hoping this is still covered in warranty.

Transmission fluid coming out of the vent... by wickdgt

Hi there, I will like some info if any one can help me. I have a 2000 Hyundai Elantra which has developed a leak at the Vent of the tranny (automatic). I can drive the car easy all day long with no problems, as long it is cruising, but when you run it a bit harder in traffic it will puke the tranny fluid through the vent, I have taken it to tranny shops and no one can give a straight answer. I have pull a little bit the dipstick out so to see if pressure builds up it will not puke it, but even like that it would do it. I have looked everywhere but no luck. Can anyone tell me what is going on? Thanks for any info:

I also have a 2001 Elantra, and have recently, over the past couple of days, experienced the same problem. The temperatures where I live has been above the 80’s for over a month (closer to 90-100), but I am just now experience this problem; however, we are in our rainy season, and the humidity has been in the 70% for the past couple of days (higher than normal - normally we have 15% humidity in the summer (high-desert), and temperatures in the 80’s). As you have done, when I experience this problem, my transmission seems to skip, jumps into gear, then my engine light immediately goes on and I lose some power upon starting out from a slow or complete stop. Once I shut the engine off and restart it, the engine light goes out and the transmission seems “normal”. I have been experiencing slight transmission slipping over the past couple of months, but have not taken the car in for a checkup yet. I checked my transmission fluid today, and saw it is brown although it is full, and think it should be red, so I most likely need a transmission fluid change; however, on a car that has 70,000 miles, and needs maybe only a tranny fluid change, would this behavior be normal?

Hi..This sounds exactly like the problem I had. I took it to the dealership since the transmission warranty is 10y/100K miles. Was informed that the transmission is fine, but the speed sensor and the cam sensor have blown out and that is sending the wrong speed to the transmission, causing it to slip. Total cost to replace was $440 and approx half a day at the shop.
