Elantra MD (2010-15) :: 2012 Auto Transmission - Downshifting And Up Shifting Quickly On Its Own
Jun 7, 2013
Had problem with downshifting and up shifting quickly on its own and then engine light came on. 24,400 mi. Code P0713 Trans Temp Sensor "A" Circuit Input. They replaced it in a few hours and we will see how it goes. Had also had a problem of acceleration by its self when we first bought it and the gas mileage not being to par. Of course they said they haven't heard of that and they did an update/flash and haven't had that problem again, also had a broke front axle.

I purchased a 2012 Elantra Limited w/Tech last Wednesday and it has about 250 miles on it now. Downshifting is kind of hard. I've been driving with Eco mode on but have noticed the same thing w/o it on.
I'll get up to 45 mph and then let the car coast, every time the car downshifts a gear I feel it in the car. It causes me to jolt forward a little bit and is not very smooth. It shifts the same way while accelerating but then I don't really notice it b/c I'm speeding up.
It is annoying while just coasting b/c it feels like the car is braking a little every time it drops down a gear. Also, if it pushes me forward a little bit then the car probably is braking a little which seems kind of against the point of coasting...

I have a 2011 Hyundai Elantra GLS... Few months back I refueled my tank with degraded fuel (of course i did not know about it and some refueling stations in our country mix oils) and the problems started to arise with my car.. initially it all started with jerks and cracking sounds from the engine.. I then took it to the dealership and cleaned everything except the injectors but the jerking and cracking problem was solved.. but it still had a pickup problem.. whenever i tried to accelerate from 40km/h to above, the transmission seems to give a jolt make a clicking sound when downshifting.. and the acceleration compared to before has degraded.. I took it to the dealership again and their answer was drive it for 300 km more everything will b fine.. but i have driven the car for 1000 km more but the problem is not solving.. I don't know.. my warranty period is over.. in our country they only provide for 12000 km or 1 yr warranty.. now i have checked online and it seems Elantra transmission has bugged a lot of ppl..

For a few months now I have been hearing a tap clunk type noise coming from under the car when I shift the auto trans into drive and reverse. Also sometimes when the car is slowing when driving I hear the tap sound as it shifts into first. I drove in by my local dealer and they listened to it and said Elantra transmissions can get noisy there is nothing wrong. They told me I have plenty of Warranty left so if something happens I will be covered.

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.

Recently changed the transmission fluid in my 2011 Elantra. Used the fill plug to check fluid. Small steady stream was coming out. Closed it up and took it for a ride. Was shifting very rough. Put more in and it felt better. Was wondering if there is a better way to check the fluid? I've heard that the dealer may have a sensor, is this true?

I have a 2012 elantra manual transmission. I noticed the eco mode but never found out if it really does anything. when I shift from 1st to 2nd at higher RPMs its rough. At other gears its ok but I feel like the gas pedal is weak sometimes. With a manual does the eco mode make that more difficult?

I have a 2012 elantra limited about 9 month's old with about 14,000 miles on it.
About a week ago I began noticing a burning smell. I first chalked it up to being 1,000 over the 3k mark for an oil change. However I then started to pay attention when I parked if there was any sign of fluids leaking. At first I didn't notice any or seemed like one or two drips. Well tonight I noticed a larger puddle that was def not water.
The other symptom is that it's been shifting up at higher RPMs. Tonight when I got on the freeway I was trying to speed up to 65 but the rpm gauge had me at over 4,000 rpms with normal acceleration...I was not gunning it. I also could not get the car to go past 60 at first, all the while the rpm increasing still, until I let off the gas then hit it again and seemed to trip it to shift and was able to get to 65.

Well something I never thought would happen with only 14,313 babied miles on my 2013 silver Elantra. I was driving home from my mothers house and I thought I hit a pothole, next I stopped at a stop sign took off and it started shifting very rough through most of the gears. I drove it around for 30 minutes and it was pretty bad. I decided to get it towed, I don't feel like breaking down in it.

I am coming from a 2001 Acura CL-S which is a 5 speed automatic, and that car wouldnt' change gears that quickly. I understand cars today change gears frequently to be in the best gear for fuel efficiency?
But I feel like my ES350 changes gears so much, even at the slightest speed change. Is this normal -perhaps it's because I haven't driven a new car since my 2001, 12 years ago! Even the slightest press on the pedal will downshift the car and into the lower gear, even on ECO setting. On my Acura, pressing lightly on the accel pedal didn't result in a lower gear, as I know the engine had more than enough torque.
I also love reliability, and this makes me think the transmission would have a shorter life span with all the shifting. I still haven't asked my dealer about how often to do tranny fluid changes (which I know is a different thread altogether about discussions about "lifetime" fluid).

I've had 2 Elantra 2012 models 1 a gls the second a limited. As far as transmission issues both Elantra's from a cold start after allowing RPM's to idle down before taking off they both have started shifting hard going from 1st to second gear 1st car was around 8-9 k miles now 2nd started at 3 k miles. Since owning 2 cars same make same year same transmission and many times to dealer 1st car ended with Transmission replaced 2nd has now started doing the same thing they reset adaptive and next day did it again its now back at dealer waiting for them to diagnose again.

My 07 AT 2.0 has a weird problem - when auto downshifting after a long drive at highways speeds, the whole car thuds. This happens after driving about 20 miles or so at 60MPH+. 5 or 10 miles are not a problem.
What happens is that when it slips down into 2nd, it sounds like something jams (no grinding). The force/feeling is similar to running into something at a slow speed - like bumping a car while parking.
If I slip into Tip and downshift manually, it doesn't happen. Outside of this the car has 22K miles and drives great.

The downshifting while braking is very obvious during braking, I can literally feel the gearshifts going down from 5th Gear to 1st as I brake. I have driven a wide range of cars but haven't experienced this earlier. Is there any modification that can be done or added to change this and make it smoother like usual cars?

When approaching a red light, if I take my foot off the gas to coast, it feels as if the transmission 'downshifts' at around 30mph. I can't actually feel the transmission shifting but there is a definite slowdown in speed, not just a gradual slowdown. Is this normal? I ask as doing the same in the '04 RX it does not do this.

I have a 2000 Ford Ranger 4X4 XLT with a 5R55E automatic transmission.
Coming out of a stop the truck jolts at about 20 mph as it shifts from 2nd to 3rd gear. It feels like it revs too high in 2nd gear, up to about 2400 rpm, and then shifts hard into third. It feels like the truck gets a gentle hit from behind.
Earlier in the week, the O/D light flashed. I took it immediately to an independent tranny shop who pulled the code for me: P7033, incorrect ratio in 3rd gear.
They cleared the code for me. In limited city and highway driving (less than 15 miles each trip) the O/D light has not flashed again. But the problem remains. I plan to take it back to the shop later next week.
What might cause this so that I might have a more informed conversation with the tranny mechanic?

We have a 2009 Matrix, 68000 miles. automatic transmission has a loud clunk when down shifting on a hill. Has only happened a few times and cant seem to make it happen. Am really concerned what this might be.

I have 2010 Camry Le 2.5l with 39600 miles on it. Bought used from my uncle. The car is pretty good but I don't like the nature of new 6 speed transmission. Its always downshifting and I can feel the drag feels like car is braking by it self. Is this transmission designed to do that? In my previous thread I post the same issue and got reply that I will get used to it but I already driven this car almost 2 months but I am not used to that drag/pull back feeling when ever I take my foot off the gas pedal. Is there any solution for this drag/pull feel?

When taking off the 1-2 shift and the 2-3 shift the truck will go into a neutral state for 2-5 seconds. when this occurs, the rpms will rev since your foot is on the accelerator. Once you let off the accelerator the rpms come down and the gear will catch. I have had the truck in the shop a few times without any luck. part of the problem is no codes are thrown so the dealer has no clue what to look for. This is extremely dangerous when in my case i pull out on a 6 lane hwy with 55mph speed limit. Ford more or less said to pound salt until a code is thrown or until something else happens. this nearly caused a nasty wreck 2 weeks ago.

I have a Hyundai Elantra XD 2004 FX hatch. About 3 weeks ago we noticed that there was an occasional rough change in the transmission. It happens mostly between gears 3 and 4, but can happen outside these gear also.
I have checked the fluid level and it always seems low. Over the last 3 weeks I purchased some transmission fluid (I used the Castrol brand for that specific car as looked up by the spare parts shop) and the problem hasn't got any better. On top of that despite adding a total of 800mL over the last couple of weeks it still doesn't appear to register between the cold and hot level on the dipstick.
I've looked around for leaks and can't seem to find any, there were a couple of drops underneath the car but I can't say for sure they are transmission fluid, I'll have to check this again soon (it's a bit difficult as it's not my car it's my wife's and when she gets home it's dark). Either way it's only a couple of drops at worst.
What this might be, and what the process I should follow to diagnose it is? If it's anything besides a leak in a hose then I'll definitely be taking it to a mechanic/transmission specialist.

My auto transmission in my 2007 Elantra with 125,000 miles went into default mode, stuck in 3rd gear. No codes went off. I drove it home this way, but after sitting for 90 minutes, now it works fine. I've heard about the input and output sensors. What should I replace? I went to HMA service to get info on both sensors, but it wasn't detailed enough.

I have read the common problems and went ahead and replaced the Throttle Position Sensor, TPS. Also had a complete tranny flush done. The shifting problem persists, when I drive around 25-40 mph, the car will constantly upshift or downshift on its own even. Sorta like I get to 30 mph and it suddenly decides to downshift, like it has become ultra sensitive to minor increases in torgue(?) or can't decide if it wants to be in 3rd or 4th gear. Did check with Jiffy Lube to make sure they replaced it with SP3 fluid and they did. What else this might be? Check engine light comes on now and then and currently is off.
