    These trannys were known to have these kind of issues, especially if the fluid wasn't changed often enough or the wrong fluid was used. The check engine light is on because the tranny computer threw a failure code to the main ecu. It sounds like your tranny is toast. The only way to fix it now is to rebuild or replace it.
  • My 1999 Accent has a check engine code stating a low voltage reading of my transmission range sensor. Where exactly is this sensor located?
  • .
    It is a Hyundai accent 1997 automatic

    Every time I step on the breaks it seems as if the car has a stutter problem , at times when i push on the breaks just a little bit to slow down the car will stall out. It turns on just fine. It will also seem to get stuck in a higher gear. Example if I am going 60 mph the rpm will read 3-4 and just sit there, i can feel it in the pedal when it does that.
    to add to that when it is stuck in the high rpm it takes about 10 seconds after a stop to get going up to an actual speed.

    The problem started out with it just stalling out every now and then but ONLY when i push on the breaks to stop or slow down , the rpm will shoot up and then usually stall out unless i push down on the gas a little.

    Email if you have any idea what i should do or why my car does this. I am a single mom and this gets very scary when im driving with my son and it will stall out as i slow down and make a turn or anything like that.

    I use to own late 80's and early 90's GM vehicles that had a similar problem with a 3 speed automatic. It was a solenoid switch in the transmission that locked up the torque convertor. It cost like $200 to fix (mostly labor) as the switch was inexpensive. I remember a mechanic telling me it's like riding a bicycle in 10th gear, coming to a stop and then trying to get going again without shifting the gear back to 1st. Good luck.
  • Hi,
    I have a 2009 Hyundai Accent, Automatic Transmission and it has been bucking a lot, AT fluid checked and it stopped briefly but it is doing it again. I have about 25600 miles on it and the fluid level is fine. Not sure if this is a sign the tranny is starting to go? The other day it would not shift up into the next gear and the RPM's kept revving high.
    I am under warranty but do not trust what the dealership will have to say. Does anyone have any knowledge of this happening to them? Thank you....

    i have a 2001 accent which will not let me turn the key back to the lock position unless i disconnect the battery. i think it may be the sensor that tells the compuetr the car is in park? I can shift the car into gear when the key is in the lock position. Am I on the right track and can this be done on my own?
  • @ shellybear0925 ...I recently bought a 2009 Hyundai Accent, and it was doing the same thing yours is doing. It would get stuck in 2nd gear. If I was driving, it would clonk, jump, and then not shift. I have had 2 trips to the dealer now, and they just replace a speed sensor on the transmission. I don't know if that is the cause, bc I just picked my car up today, however.....I will definitely let you know...bc it has been a headache for us...hope this helps!!

    ok. The transmission fluid is pooling on top of the transmission. It's having a hard time going into gear and sounds like it will rev up and up and up and not switch gears until there is a really hard shift. Fluid is not burnt. Finally drove it on the highway about 40 miles and it jerked really bad and was making loud noises. I had it towed home. Does anybody know whats wrong? also while driving the rpms will go way to high before the shift. Had a tranny rebuild about 50000 miles ago. i use the hyundai fluid also. was doing the jerking thing off and on then just went to all the time. no trouble codes or check engine light. overdrive stopped working.
  • also when it gets going faster then 40 or 50 mph it seems to loose speed

    Did you find out what the problem was as I'm having the same trouble now?

    Did replacing the speed sensor work?? I also have a 2009 accent and it's doing the same thing. Thanks!
  • I'm having an intermittent problem with my Hyundai Accent. Usually in the mornings... come to a stop sign. Then when I take off, it feels like it's not getting enough gas. Hyundai dealership has had the car 3 times and no issues found. No engine light comes on. So they can't diagnose
    it.
    Can anyone help me out?

    I would look into the coil packs, which control the spark. There are 4 of them, the small black boxes above each spark plug. These are known to go bad on the Accent and they cause poor acceleration, sputtering, jerkiness, etc. They don't always throw a code when they go bad.
  • its true, but 1st check your grounding connections- all sensors ground to frame or trans body - they must be clean and di electric greased. check battery connections check fuses . throw a meter and check for trouble codes - for 10 bux try seafoam and try and loosen the selenoid. if that works, change filter and fluid
  • Hello, I had the same EXACT problem with my 05 accent, I have been trying to figure it out for almost a year now. I dont know why, but NO hyundai dealer ANYWHERE seems to know the true cause of this problem. However, I for one found the cause of the problem yesterday as i was driving down the interstate. My accent was doing 65 mph when it kicked OUT of overdrive and my rpm's shot up. I pushed the overdrive button on the shifter to off and then back to on as i was driving and the car went back INTO overdrive as it should. That led me to start playing with the overdrive button while i was driving. As i wiggled the button back and forth the car would kick in and out of over drive without actually PUSHING the button. About two hours ago i pulled my car in the garage and took out the screw on the front side of the shifter that hold the overdrive button in and finnagled the overdive button out of the shifter. I found that one of the wires on the overdrive swith was frayed. This is because of the way hyundai runs their wires through the shifter. There is 3 different colored wires. One of them is black. This is a ground wire. The other two are different color. If you touch one of the wires to the black ground wire, the "over drive off" light will illuminate on the dash. If you touch The OTHER colored wire to the black ground wire, the "over drive off" light will NOT illuminate. This means the overdrive is in fact enabled. As i never turn my over drive OFF anyway, I simply cut the wires off of the overdrive button and soldered The ground wire to the colored wire that enables the overdrive. My overdrive is now permanently on and my car does not stick in 3rd gear at stops signs and it now shifts through EVERY gear as it should ALL of the time. I took my time to explain all of this because i know how confusing the situation is and I KNOW FOR A FACT that this is the cause of your problem. I joined this website ONLY to reply to your post. I am giving you my word that if you do what i explained your problem will be solved. I thought it to be highly unlikely but i proved myself wrong. I hope you give it a try. -Joe
