Hyundai - Elantra :: 2011 Automatic Transmission / Harsh Shifting
Jan 27, 2015
I have been having phantom automatic transmission problems with occasional harsh shifting, mostly up shifting through all the gears but sometimes downshifting. This problem started in May 2014, lasted off and on for several days, and then stopped occurring. There had been a few instances of small drops of fluid on my carport but nothing consistent. Then in September, the problem started again on the same basis: on/off again, nothing consistent. When I couldn’t locate the port under the hood to check the transmission fluid, I took the Elantra to the Boise Hyundai dealership to ask where the trans fluid port was located. My service rep told me that there was no port in the new vehicles and that the transmission fluid was not changed until 100,000 miles at a cost of $400. The service technicians could not find anything wrong with the vehicle when they hooked it up to their computers to check the error codes, and the vehicles would not perform the harsh shifting when they test drove the car. The techs re-set the adaptive points and I was sent on my way. A few days later, the harsh shifting started again on and off, phantom problem. I took the Elantra back into the dealership and told them to keep it for as many days as it took for a tech to drive it home and start it cold in the morning. The transmission did not perform the harsh shifting for the 80 miles the tech drove it home and back to the dealership for three days.
After driving the Elantra another week, the phantom trans problems re-occurred. After surfing the web and checking the Hyundai Customer Forum, all I could find was problems with 2010 Elantra transmissions and my service tech admitted that Hyundai had replaced thousands of 2010 transmissions.
Through the dealership I opened a Case File for my transmission problems because there is something definitely wrong with the vehicle and I want a new transmission, and will press my case to the max. I’ve kept a log since September, noted daily temperatures, and times the trans has performed harsh shifting. I’ve kept the problem to a minimum by letting the car warm up for about 5 minutes and will only drive it when the tachometer needle rests on 1,000 rpms.

2011 Elantra with phantom harsh shifting problem. Yesterday the Elantra began surging and nearly stalling out on acceleration after about 20-25 minutes driving. I was barely able to drive the car home; when pulling into the garage, there was a strong smell of something hot. Temperature gauge indicated normal engine temp; no icons lit on the dash indicating a problem. Surging/nearly stalling and overheating problem and is it related to other Elantra engine, trans, fuel system-related problems? I can’t find anything specific while web surfing today for some clues!

I have a 91 Miata Auto. I bought it from someone that (I think!) never drain auto trans fluid during its 145K mile life. So last year I replaced all the gaskets/filters and tuned up the car. It runs fine except shifting harsh in cold weather. I have to mention that it seem to have no power and goes very slow on first few minutes.I used a pump to suck trans fluid out. It was so dark (even I dropped the trans pan and replaced filter/gasket). Then I pumped Lucas trans fix fluid in and it seem to improve. What should I do more to reduce the harsh shift condition in cold weather? Or is there a booster module need to be replaced?

My check engine light has recently turned on in my 2004 hyundai elantra, and since it has come on my car will kick and sound like its going to stall, works but the automatic transmission refuses to shift. This inconsistent because it sometimes works fine with the light on and sometimes the light won't even turn on and everything is ok. What's wrong?

i have a 2001 elantra with 136k. the automatic transmission (which otherwise shifts very smoothly and shows no sign of problems) shifts suddenly and erratically when i'm driving at a constant speed. I'll be traveling along (speed doesn't matter), and it will suddenly downshift, then upshift, then downshift, etc. this started off being very occasional, but now it randomly shifts every 5-10 seconds.
I've changed and checked the fluid, and tried replacing the Input Speed Sensor and the Output Speed sensor...that didn't fix it. it also does not blow a check engine code. I'm convinced there must be a sensor somewhere that is faulty. it really seems as though the transmission is electronically confused.

I have an automatic 2010 Elantra Touring and I drive 115 miles a day (4 days a week) with it (currently have 38K miles). Part of the drive goes up over an 1100 foot foothill, so I change elevation of about 800 feet on the drive. Over the last two weeks, I have noticed the transmission shifting a little rougher and at higher RPMs (everywhere and not just going up the hill). The transmission fluid level looks good, but I am wondering if I need to change the fluid and filter? Or is there something else I need to look at? I need this car to last another three years and want to make sure I take care of it right. Currently every 3500 miles I change the oil and rotate the tires, but I am just not sure about the transmission.

My automatic transmission slipped today. Really worried now. 2011 elantra with 36k on it. It was raining and I was turning right out of a shopping center. I floored it to beat the incoming traffic and the tranny slipped. It hasn't slipped since then and has been perfect so I know the dealer will say they can't replicate the problem. Should I be worried about this?

I purchased my car almost two years ago. I drive a lot for work, and my car now has 74000 kilometers on it.
So far its gone thru 3 CV Axle Joints on the drivers side, a radio unit, clutch bearing, fork, and fulcrum, and now there's something wore out in the rear suspension (squeaking and snapping).
The transmission in mine has also started to grind when shifting like the syncros are wearing out. Motor knocks when it's cold, sounds like the top end goes dry of oil when sitting overnight and takes awhile to get any.

I have the 2000 passat 1.8L 4 cylinder with the tiptronic shifting. The car has been shifting less smoothly both upshifting and down. I have noticed that if you are going fast and slow suddenly, say for a light and the downshifting does not go smoothly the vehicle can lurch/jump even if the brakes are firmly applied.
What may be causing this issue. I recently sold my MKIV which was a great car and we are now starting to have small problems with this passat with 104,000 miles on it. It does not intuitively feel that the tranny is worked over yet, but I would like to avoid any expensive repairs/replacement. I have done everything from suspension, door replacement, clutches and timing belts on other vw's. So I am hoping to tackle this myself.

Vehicle: '99 E350, V10
Symptoms: speedometer bouncing, O/D flashing, harsh shifts. Symptoms do not present until the van has been driven at highway speeds for about 20 miles. Then, the speedometer starts to bounce a little. Then, after another 5 - 10 miles, the O/D light starts to flash. Then, with a few more miles, the harsh shifting begins.
Parts replaced: neutral safety switch, rear ABS/speed sensor (twice), instrument cluster.
Each time after I replaced a part, when I drove the van, all was fine until it had been driven at highway speeds for about 20 - 25 miles, regardless of whether the engine was warm or cold. Where to go next with it?

This is a pretty strange situation. A couple of years ago, my automatic locks stopped working consistently in hot weather. Sometimes they'll work and sometimes they won't, but the worst thing is that they are inconsistent. I only have this problem in the summertime or on really warm days in the spring or fall (I live in Colorado). What could cause this?

I have a 2005 Elantra where my transmission went. The tranny had a harsh upshifting when driving, also had it in the shop four times because it was hard to get into Park or Drive. Shop said they never could find a problem.. Did some checking on internet, the Accent and Elantra shared the same transmission I believe, and found a TSB describing trans axle solenoid problems from 1999 to 2006. I am going to fight this as I don't think I should have to pay for a factory defect.

Noticed cup holders above the transmission a little warm. I have a 2011 hyundai sonata se; when I drove a regular sonata I didn't notice the cup holder getting as warm as my car.
I have also started to notice that the transmission shifts into 1st gear a little harsh vs the rental sonata as well. I did do my own transmission drain and fill with Amsoil fluid. Why its shifting like this?

I have a 2007 Sonata, performs flawlessly, my wife's 2011 Elantra, not so much. We've had issues with her car from the get-go. The Elantra has 32k miles on it. About 15k miles ago the dealership reprogrammed the transmission. Problem seemed to be fixed, to a degree. Hiccup here and there.
Last night when my wife came home from work she said it was shifting hard. I just shrugged it off. We came in to town, about 5 miles down a busy highway. 55mph, no problems.
Car sat for a couple hours. We got in the car to come home, buttery smooth first few shifts to 35 mph. Car had probably been running about 5 minutes. Pulled out onto highway, shifts 1-2 fine, 2-3 holds about 2500 rpms, won't shift, won't shift, BAM! repeat 3-4, and I believe 4-5. I was so shaken up I didn't count. I pulled off and took the back road and it continued to do it for about 3 miles. It almost feels like the torque converter is locking up. Someone mentioned a transmission temperature sensor, but that is only in Sonata's, no one has seen it in an Elantra.
By the time we got home, the car was shifting normal. This morning I get in it because now my wife won't drive it, and it works fine. Works fine all day.
Go into dealership, they say everything is fine, they called Hyundai, they say nothing wrong, come back when you have a problem.

Any input on replacing the entire transmission valve body or just individual shift solenoids? My truck has begun experiencing a harsh shift from 1st to 2nd under light acceleration accompanied by occasional shift flare from 2nd to 3rd and 5th to 6th. I have located parts to do either job. It looks straight forward from just disconnecting the harness. I also understand there are different bands associated with the solenoids. Is there a requirement to have new transmission programming to accompany swapping these components?

My alternator recently died and I took my car to a shop to have it replaced. Since receiving the car back, I've noticed that the car seems to jerk at random while shifting. It seems to happen most when shifting from 1st to 2nd. This problem didn't exist before I had my car maintained. Any chance this is related to the work done and is something easily fixed or is it just coincidental timing?
It's a 2004 Hyundai Elantra, at 120k miles,,,

Experienced an accidental shift from automatic to sports mode when attempting to "park" your Sonata? It happened to me last weekend. My car shot forward like a torpedo, doing considerable damage, not just to my car but to others as well. I have often thought it takes no effort to switch to the sports mode, but have never used it. Now I wish it were not available.

My 2007 V6 failed me several times on very cold mornings. I start the car, wait about 1 minute and then drove it to a stop sign or red light (still cold). When the light turned green, I tried to proceed, but it was as if the car was in neutral. The car would not move. It was only after about 2-3 minutes, when the car started to warm up that I was able to get a gear. After 5-7 minutes, it was as if nothing happened. I have 97K on the car.

So yesterday after running an errand I got home, after having dinner I was about to head out and, SURPRISE! The car wouldn't start... The engine doesn't turn, no lights on the gauges when inserting the key, no clicks.... the battery seems fine, as the radio works, the anti-theft/alarm works well, the 2nd key behaves the same way.
This morning, I called VW road side, the tow truck they sent couldn't take the car because it is in a tight spot and we can shift the car to neutral. We tried resetting the ECU by disconnecting the battery without success... What to do??

Just this morning I noticed that the first shift my automatic transmission makes is not so smooth. Almost like I'm getting a slight shove from behind. Repeated at every stoplight. I know I'll be calling the dealer tomorrow, but am hoping to get ahead of the curve and be prepared for what it might entail.

I've got 95k miles on my 2001.5 and have been noticing that the transmission seems to shift pretty hard. Today it seemed like it was hardest in the 3rd to 2nd downshift. I got it checked out a couple of months ago and the dealer said it was the throttle body (which I haven't cleaned yet).
