There aren't much resources online covering transmission fluid changes in these new models. It's pretty straight forward. DO NOT LISTEN TO THE DEALERSHIP TELLING YOU IT IS "LIFETIME" FLUID. Just use this video for reference of what that fluid looks like after ONLY 35K miles and the HUGE amount of metal shards flying around in the fluid/on the magnet.
Hope you guys find this video helpful.
TOOLS:
Patience
10mm socket
24mm Socket
3/8 & 1/2 inch drive ratchets
6 inch extension
A Jack or Lift
TIPS:
--Don't drill through your transmission pan as it is plastic too.
--Using a file to cut the notch is safer but slower. If you do use a drill, set it to the slowest setting.
--I forgot to mention that you should jack up the passenger side after you pull the plug to get ALL the pan fluid, there will still be the other half in the trans though.
--You can remove the air box as a whole and not have to separate it in half

I was able to get the plug in and out with no problem. Don’t be afraid to use a LITTLE force. It only needs to make is past about an 1/8 of an inch so it’s bends.
Do you know how many quarts came out thanks
Would you be willing to post a video of your way of pulling it passed the neutral safety switch?
Cory 919 Brother, maybe next time I service it. All I used was a heavier flat tip screw driver to put just enough pressure on it to get passed that 1/8 bend. I did it a couple times actually. Don’t be afraid to use a little force
Same here. I was able to get it out with no cutting just by angling it slightly away from the interfering tab and pulling up by hand, no tools and with just a little bit of force. Putting it back proved to be more difficult, so I filed a very shallow (~1mm) half moon in the plug while it was on my work bench.
@@cgatito3528 I did the same.. I got a small course file , and filled a 45 deg on the bolt while it was still installed on the house..works perfectly now...easily removes and installs.. All is good now.... Thanks all...
Tip for next time, you can always pull the emergency brake and use the shift lock on the shifter and put it in drive. That will move that shift Linkage that’s in the way so you can easily remove the fill plug without buggering it up👍🏻
Lol i hate u but i Love u buggering it up made my day thanks i needed that Laugh
Thanks for the video, very helpful! I just changed the factory fill atf in my 17 Elantra at 140k miles. There was a little bit of shavings on the magnet, nothing visible in the fluid. Fluid was slightly brown with clutch material but not burnt. Exactly 4 quarts came out of the drain plug. Repeated drain/fill a second time after a quick spin to get more old fluid out.
I filled with valvoline maxlife, it had the Hyundai spec listed on the bottle, is full synthetic and only costs $17/gal so I feel good about it. IT STINKS LIKE HELL THOUGH! lol. I spilled a little in the engine bay and it took a week or so to air out. I’ve put 10k miles on the new fluid with no noticeable changes in performance, so I think all is good!
wow, that's a lot of miles, I drive around 40k miles a year, I already sold my 2017 Chevy and now I have a 19 Elantra and a 19 Elantra GT
How did your Valvoline Max work in the long term.
@@johnjohnson9980 just fine, sold the car at 200k with that same valvoline fluid and no noticeable change in performance. Car still ran like new
Excellent video. I’ve already performed this twice on my 2017 Tucson and getting ready to do it again after I just flipped 180,000k…
I still shake my head when I hear “maintenance free transmission”… Your fluids are the life of your car. Change them or suffer the consequences..!!!
You are the hero we didn’t know we needed. Also, bless you. I just hit 120,000 on my 2017. Looking to change that soon along with my antifreeze/coolant. Thank you for the video bud.
Chang it every 60,000 miles, ATF.
At 120,000 miles you would not be wise to NOT change the transmission fluid.
YOU may at this point do more harm then good.
A few questions if you don't mind my asking. Do you have the 2.0L engine and did you have to get it replaced? Has your Elantra had any transmission problems? I bought myself a new 2018 Elantra and the engine ran like crap from the first month of ownership and the transmission started acting up at 8,000 miles. It wasn't safe to drive and the dealership was no help. Ended up selling the car at 25k miles. I loved the car so I was really disappointed by the problems.
Lifetime fluid my ass, you did the right thing by changing your fluid. You notice they dont even put a dipstick in the transmission because of "lifetime fluid"
My 17 elantra we bought with 40 k. 60 now. Amazed what you found in yours at 30 or 35. Thanks for video
Exceptional video!!! Great job. I undid the neutral switch bolts and the fill cap came off beautifully. Easy job. Use OEM FLUID AT ALL TIMES. Mine drained 3.5 quarts out.
Terrific, thoroughly explained video. Thank you very much. HUGE THUMBS UP!
I already did it in my 2013 elantra at 60,000 mi. last year. I use the same fluid SP4-M from the dealer $20.23 each. I use 3.9 quarts just drain and refill. Great video.
So about 4 Quarts is the Norm. On these Transmissions Good 👍😁😚😏
I just did this at 58k on my 2017 Elantra GT. I don't see much content revolving around the GT, but this and similar videos worked well enough for me, though there are a few differences:
1. I didn't need to remove my splash cover to access the drain bolt, but I did anyway for the sake of doing it the first time. When I started, I realized I could see the drain bolt right away and the cover wasn't in the way. I think next time I will leave the cover on and see how that works for me. Though I'll probably have to take it off to check the level so I may be stuck with removing it, haha.
2. The fill bolt on my GT is the screw-in kind. It tightens all the way down, and I had to unscrew it for a bit to get it out. It's not a half or quarter-turn like on the sedans.
3. I did not have to file down or cut my fill bolt in any way - that part you had trouble with isn't in the way so I had no problems getting it out. :)
4. When I unscrewed my drain bolt, it did not have a crush washer, which I thought was strange. I added a copper washer and torqued to 30lb/ft as suggested in another video.
As I said, I did this at 58k miles. The fluid was pretty dark but not burnt - still a little red/pinkish in tint. I ran out of daylight so I did not get a chance to check the level, but I drained four quarts roundabouts and I put four quarts back in. Tomorrow when I have sunlight I'll add a little more fluid and check the level. Thanks for your clarification on that process, by the way.
Hope this helps any fellow GT owners out there. I'll try to document my experience as well - maybe record something though I never have before. :p After checking the level tomorrow, I'll probably drive around for a couple of hundred miles before a second drain. I used Valvoline Maxlife ATF - it claims to be up to spec and the most important thing for me was getting this fluid changed, so I'm hopeful it'll work just fine, especially after reading that other GT owners use it.
Update: Checked my level at operating temperature and got a small steady stream. :) Woo!
Gotta do mine tomorrow, thanks man!
Thanks for your comment. My wife has 2016 Elantra GT with 67,500 mi. and never change the atf. I will do the drain and fill with the oem hyundai sp4 fluid but reading your comment I'm leaning to use tha Valvoline Maxlife. Do you have any problem at all using the Valvoline? Thanks again your reply is really appreciated.
Your video is very helpful and inspiring. I have never done something like this but I feel very confident that I can do this. I have a 2017 as well so I will have the same issue removing that plastic bolt.
I'm taking my 17 elantra to the dealership tomorrow for this service. I have 53.000 miles on it. Paying 289 dollars. Well worth it to let them do it. Any issues down the road, they can't say I screwed it up.
Huge thanks for taking the time to make this video. I will be doing this soon on my daughters car. There is very little imfo out there on this and your video helps alot.
I absolutely 💯 percent agree. Change your fluid!!! Thanks for the info. I think I'm going to try loosening the bolts on the linkage that is in the way and see if I can't get the filler plug out. I'll let ya know
Once I learned of the price of the fluid (genuine Hyundai, so I don't void my warranty), I decided the $249.00 my Hyundai dealer charges to do this on my 2018 Elantra was well worth not dealing with changing this fluid myself.
Heya I just wanted to chime in and say thanks for this vid. Helped me change out my transmission fluid as a car novice
the ATF on my 2018 Elantra was pretty close to black at 50K miles. With the 3rd drain and refill, I started the car, switched through all the gears 6 times, and then let it idle for 5 minutes pulled the check port /plug at @13:39. Then I slowly added ATF back in until I saw a tiny stream of ATF come out. Popped the plug back in while the car was still idling. If you stop the car first before re-installing the plug, a lot of fluid will spew out.
The easiest way to remove the plug is literally just put an extension on a 3/8 wrachet and put the end of it in the square on the plug.... Makes it so much easier
I did the change again recently at 100k miles. I wouldn’t change any of the information found in the video.
Shifting into neutral doesn’t do anything to create extra clearance for the plug.
This time around I used Valvoline Maxlife. I have noticed that the car will upshift sooner now, I believe it goes into 3rd/4th at 25 mph instead of 30mph when driving normally. I’m not sure if this is because it’s fresh fluid or because it’s Valvoline. I have noticed that when cold, it takes an additional second to start moving after coming to stop. Again, I’m not sure if this is because of clean fluid or because I’m using Valvoline. This could also be because of a dirty/clogged filter. I would suggest sticking to OEM fluid to get the longest life out of the transmission.
I believe you’re supposed to shift into drive not neutral to create clearance
A little late here but I am sure that the part in the way of the drain fill plug is the transmission shift linkage just shift the vehicle in neutral or in another gear and then pull the fill plug out
Thanks great video people need to change their fluid at least every 40,000 mile
I have a 2017 elantea se. I always wanted to do the atf fluid change. Thanks for the video. I did take the risk and did it yesterday at 111,000 miles(I do rideshare and deliveries). Atf was really dark but drain plug had less debri, so I am hoping I did this on time. Also I used atf from Ravenol instead of the dealer brand, which is way cheaper, I got it from amazon. To cut the cap y used a garden pruner tool(scissor like w/one flat side)it only took 2 cuts a less than a minute. To refill I used a hand fuel pump which i bought at a family dollar for like 3.25
I did measure and it drained 4l and 100 ml. I only put 4l back
How is your car driving now?
So far it shifts smoother,however, I have only put around 500 miles
That's wonderful. Can you share a link of the kind of tool that you used to cut the fill cap? I plan to change mine soon as well.
@@roman75236 that's awesome. There were so many, so was wondering what to use. Thank you so much. :)
Great video...I could not tell, but he car should be running when checking the fluid
It's not lifetime. It's every 150k in the manual. I changed my 16' Elantra at 97k. It looked great still. Had metal shards but nothing excessive.
I’m glad I did not have to deal with the part covering the full bolt on my 2015 Elantra
Silver Fever I’m going to be doing a change on mine and it’s a 2015 as well lol
Make sure to use the Hyundai SP4 fluid from the dealership
Thanks for the video man. I bought my 2015 Hyundai Elantra sport with 65k. It's around 72k now. I believe they were mostly highway miles. I'm going to change it now.
That's what Hyundai calls the inhibitor switch lever, in English use to be called the neutral safety switch. To get it out of the way, have to get the thing out of park, has that cap next to the shift lever, remove that and poke a rod down there, like a stick or screwdriver. Course, make sure your wheels are blocked, also have a parking brake so you don't kill yourself.
Would only use genuine Hyundai transmission fluid, had friction modifiers in it you may not find in aftermarket. The way we drive, good for 160,000 miles, but the warranty is only good for 100K miles or ten years, whichever comes first.
well explained! I was planning to put mine in neutral after turning the Accessory mode on.
I called my local Hyundai and asked how much is a quart of Hyundai SP-III AFT for my 2012 Elantra cost, and I fell of the chair when he said "$39.99/qt". I said "13.99?"... and again he confirmed "NO, SIR... $39.99 a quart". I was like "Wow, are you serious?"... "The price is $39.99 a quart". Obviously, I did not buy it from that dealership.
My well maintained 2013 Elantra LTD with 91k mi. on it . . . has never seen the dealer since purchase and it won't. You know how I got 91k trouble free miles on it . . . I took charge of the maintenance and most important . . .
I kept the dealers damn hands off of it.
Quality Oil, OEM filters, Quality ATF, NGK PLUGS, BRAKES, TIRES . . . NONE OF THIS IS ROCKET SCIENCE . . . " LEARN " FROM A KNOWLEDGEABLE FRIEND . . . LIKE THIS GUY . . . OR GET A TRUSTED MECHANIC.
Bullshit. I paid 17 per quart from a dealer

Unless the car was overfilled at the factory, there’s absolutely no way of overfilling the atf if you put exactly what you drained (cold hopefully)
Unbolt the 2 bolts on your neutral switch and twist it a bit
To take the filler plug out, shift the transmission out of Park. That will move the obstruction out of the way.
I got a 09 Hyundai Accent wish I could do a drain and fill on atf but some people don’t know how to do proper maintenance car has 104,000 miles so it’s kind of risky but great video
It worked best for me when I jacked up the passenger front side. It drained way faster
Why you changing the trans fluid after only 35k miles? I thought the trans fluid is changed when it hits, 100,000?
60k - 80k miles is ideal range. 100k is too late
@@vuvu3421 Owner's manual states first fluid change at 150k miles. It's synthetic fluid. Lasts longer.
U dont need to change it on an automatic 2015 elantra since their sealed
@@tiana1017 wrong
@@palebeachbum owners manual is not always true. You can see in the video how bad was the fluid after 35k miles.
After your warranty is expired, your trans will be broken and you'll need to fix it at the dealer; and that's how they rip you off
With a flat screen drive you can remove the cap without damaging it
Elantra seems to me that it has the same kind of transmission ( dual clutch) as my Hyundai i 30 here in Europe. A few months ago I got my i 30. When I asked Hyundai dealer about changing oil in my vehicle's transmission they said to me that it is life time oil, no maintenance LOL. Yeah, it was hilarious, and sad at the same time. By the way thank You for Your video ! it is a First video on how to care and change oil in HYUNDAY'S and KIA'S Dual clutch trans... I hope Hyundai authorized mechanics are watching this video and learning !!!
this is a 6 speed torque converter auto transmission, not a DCT, but I'm sure the procedure is similar, the dry DCT holds very little fluid from what I know
Its a shift selector for prnd
Do i running my car while checking?
Thats the gear selector if u just change to drive make sure ebrake is on
An FYI. Call ahead to see if the stealership will sell the trans fluid from their bulk container. If they do, take an empty gallon jug and get 3.5 qrts. I get it from my local Kia stealership for $7.89 per qrt. The Hyundai place wanted $21 per qrt.

Lmfao bless you 15:09 😂😂😂
2017 Elantra SE. 210k miles. Transmission started jerking going into 2nd and 3rd gear. I only drained atf once at 100k. Advice: drain atf every 60k miles. Draining and flushing is different. Transmission holds about 11qt, draining only gets rid of about 4qt.
I didn't realize it at the time but the first sign of transmission going out was a lil slip sometimes while doing around 70, it would feel like it hit a water puddle
Once the car started jerking I drained and refilled the atf. Problem got worse. I used some Lucas atf additive and it improved it somewhat
Any update?
@atrivproject Transmission shop diagnosed it as bad transmission but they were wrong. I keep driving it like that and check engine came on with a missfire. Turns out everything was caused by cracks on sparkplugs porcelain. I replaced the sparkplugs and that fixed it.
Yeah even though I do most of all the maintenance on my 2019 Elantra. For 289.00 I’ll be taking mine to the dealership for a real transmission flush. Not worth that hassle. 😎

Actually that's the wrong fill plug cause that's the breather plug to release air. The filler port/plug is on the rear part of engine.
WHY then does everyone use the plastic one under the air box then?
Great video. My daughter's 2017 Elantra is due for service and I thought the dealer was bending me over on the price @ $250.00. After seeing this video, I see why. At nearly $80 for the fluid alone, I'll let them deal with their BS engineering.
It’s not the techs at the shop who do the work that it’s there BS engineering. The techs did not design or engineer anything.
It is lifetime. Lifetime of the WARRANTY that is. Any transmission fluid will last throughout the warranty which is only 60k-100k. Once warranty is over and your transmission acts up, they're not responsible and you're screwed with transmission cost.
I'm glad you and others in the comment section are smart enough to realize this. Believe it or not, over 99% of the new car buyers never think about this thoroughly and only deal with the repairs when it breaks down. 😂
Either that or they don't plan to keep their car, hence sell it. Then used car buyers end up dealing with it.
I am curious why they made it so difficult to exchange transmission fluid. But you did a great job.
Cuz they want you to use their maintenance center
I’ve heard that the reason why your shouldn’t change your atf is because clean oil will eventually cause some clutches to slip. Maybe this only applies to transmission that are up their in mileage but the tiny metal particles in dirty oil allow for better contact when clutches engage. Cleaner oil is smoother and when clutches are worn the clean oil lubricates too good and causes slippage ... I’m not transmission expert but it’s just a thought yo.
Why is it that if you add the amount of fluid that was taken out why would you have to check it again
When you keep it in the light, the plastic plug looks like it has a tiny hole right in the center, sort of a vent hole
Very interesting video. Thank you for leading us in this effort.
Just drain out from the bottom metal plug and measure what comes out and put that amount back in. Get a new crush washer for the drain plug. Torque back to specs. Own more than Kia / Hyundai and never had a problem doing it that way.
Move the gear shifter. Works every time.
How much Quarts need it?
Thanks for the video I was wondering where exactly do you place jack ad jack stands
Can you make a video on the proper way to jack up a Hyundai Elantra thanks
Hey can i get a link to that website you used for instructions on about 17:05. Id like to go over it. Also does anyone know if you take the cap put completely to check level or partially?
Do you have to change the transmission filter?
Think the car is supposed to be running while you open the sight plug
Thanks for the video I can do this with confidence now. You think valvoline Max life syn atf will be ok
I wonder if you could fill from the inspection plug, like you do with a manual trans. You would have to pump it in. great info thanks.
Exactly. That's how it's supposed to be done. Not by fucking with that plastic plug on top. And you should measure exactly how much comes out and put that much back in
WELL, THE CAR CARE NUT ON YOU TUBE SAYS IT IS BETTER TO NOT GET RID OF ALL THE STUFF FLOATING AROUND IN THE TRANSMISSION..I AGREE.
Do you check the fluid level when the engine is off or while its running?
I would have driven around for a couple hundred miles before doing the second drain and fill. You checked the level with the vehicle running right? I waited till 60k to do mine.
Yes, with the car running
When I did the drain and fill on my KIA, it was even worse, the second drain and fill was much better. These metal shavings are normal for new car, but keep an eye on it. Granted though, I did the same on my 2009 Camry V6 at 120,000 miles and it had less shavings after 120K 😂. Lifetime fluid 😂,yeah, whis life time?
The owner's manual for these cars says the first trans fluid change at 60k under severe driving, which most people fit based on their criteria, or 120k miles for "normal" conditions. That seems way too long. Seeing the shards on your drain plug at 35k miles makes me wonder if that's what was wrong with my 2018 Elantra 6-speed auto. It slipped when shifting gears getting on the interstate at 8k miles and did it again at 10k miles in the same situation. Then at 15k miles it started slamming into 2nd gear when accelerating and decelerating. A real headache because the dealership wouldn't acknowledge anything wrong with it.
Holy shit, 8 quarts for $173 for a car that come with plastic trans fluid fill plug. I should stop complaining about toyota WS fluid price. At least they are widely available for around $105/12 quarts
Sorry for noob question. When you drain/add transmission fluid the car supposed to be leveled, correct? So, suppose I put Elantra on 4 jack stands and engage parking brake when I’m doing this procedure.
Would it be safe to start the car, go through gears while car is off the ground??
Bro, thanks a lot for this vid, I started looking for this 6 month ago because I put 65K mi on my 2017 hyundai elantra se and I was super concern about the transmission especially because I've owned other Hyundais and got transmission issues. By now I'm almost at 80k mi... This video was SUPER helpful. If you have any extra tip or observation please let me know, I'll be doing this next week. BTW, what about the transmission fluid filter?
I put some tips in the description. And thank you, I wanted to help out because I knew information was scarce. Somebody else also asked about the filter but heres the reply:
From what I've heard, the trans filter is behind the valve body when you take the pan off so it isn't an easy replacement. On the bright side I heard the filter is more of a mesh than a filter so it shouldn't clog up that much. But, this is more of a reason to change fluid more often in these cars.
Did you do the change? Were you able to remove the fill plug without filling/chipping it off?
@@josetheweirdo thank youu
What can I do for elantra transmission high mileage like 124000 mile without any change??
Can we empty the whole fluid 7.3 litre at the same time as a mechanics working with mercedes said it can be?
Thank you in advance
i had 56K miles on my 2017 elantra, is it safe to change the transmission fluid?
I wonder how the dealer does this fluid change. Do they cut a notch In the fill plug or do they take that piece off the trans
Dealership uses a fluid pump to pump it in through the drain plug. Google “transmission fluid pump” and you’ll see what I mean
Good God man. Who trashed the inside of your car?
Can you turn on the car before filling up the transmission fluid, so the trans can push the rest of old fluid out?????
Thanks for putting this up. Very helpful
It's an excellent job I benefited from
I have the Elantra 2018 and I want to change the oil
How much liter do you need from your experience
I went ahead and did the change on my 2018 Elantra as well. I've also included some tips on how I filled the fill bolt. Here is the video link - ruclips.net/video/_c19XUnyVUs/видео.html.
Let me know if you have any questions. I have a 2018 as well :)
Late with the post but how many quarts will fill an empty transmission and what size socket is needed to open the valve to check
Well mine is 189km sofar I didn’t do it I know I have to do but it driving really rough the gears are changing slowly not quickly as it’s suppose to be but the procedure has to be at once sofar I can see the service doing by our own it’s gonna be three days three times to filter out the oil of the thing completely it’s needs to be drained the old oil I mean.
So that’s your shift linkage I guess yours is in the way mine isn’t which is odd maybe you had it in gear or something but I would’ve tried shifting your vehicle from park to drive or something
Thanks for the video do you have a block on your floor jack
Doesn't the vehicle have to be running to fill the torque converter? (edit: to check the level I mean)
Same Q. I know what temperature it has to be at. Does it have to be idling or turned off.
how many oil transmision i need to put en 2017 hyundai elantra se 2.0 i put another transmision now is amty
Check out video from S&E Garage. He checks fluid level with engine running, which I believe is correct.
hello the computer needs to be reset after the change! or if I roll the car how many miles should my car go to reset! or should I disconnect the battery and reset?
Did you run and let fluid move though system fill up voids before opening side plug ?
isn't that the linkage for the transmission where that (Fill)plug you damaged is? just move the gear selector??...from inside the car....till you have clearance?
That’s what I did
@@TerminalChillness "No Damage" correct? good way to start the New Year! Be safe out there!
Awesome Video! I encountered the same exact problem, you cannot remove the fill plug because there's that part is in the way. A wise decision to change it soon. I had a question. Does the fluid fill slowly using that funnel?
No, the fluid slowed pretty quick. As long as you have a funnel that doesn't fit snug, it will allow air flow and the fluid will flow right in.
Where did you get the info to do this, that would be good to know
I have a 2020 hundai elantra sel, is it the same set up as ur 2017 elantra?
Thanks so much for this video man, very much appreciated !
I have a question will low fluid make your car not go in drive. I have a 2016
It's a possibility. The transmission relies on the fluid to create pressure and shift through gears. You can check it's level using the method I showed in the video and go from there.
Awesome video! Well done.
I have a 2019 Elantra I’ve already put 45k miles on so I’m planning on doing this soon. I don’t trust the dealer at all. Plus it doesn’t even seem that difficult.
did you buy it new or was it a used rental car? I have 18k on mine, doing mine pretty soon since it was 90% heavy traffic city driving.
I have a 2018 Value Edition, so I assume everything in your video applies to mine, as well. How did you go about getting that notch put in the filll plug so that it could be removed?
I used a drill with a small bit at the slowest speed possible as well as a triangular file. ***You have to be careful when you do it because the pan itself is plastic so if you slip with the drill at high speed you can puncture the transmission pan and cause yourself a ton of grief!! I recommend setting it to the slowest speed you can put it on and having patience.***
And do not drill through the entire bolt, just enough to put a notch in for it to slide out
I have a 2018 Elantra as well. This is exactly why I am holding back on removing the fill plug. Else I would've done an ATF change by now. If you ever do it, please make a small video. It would help many. I will also give it a shot and will definitely make a video if I do. :)

You check it with the engine running.
Apply a little common sense if you had left the transmission in the D position and set the parking brake, you would not have had to shave a corner off the fill bolt. Leaving the transmission in Drive moves that "finger" out of the way that is obstructing the removal of the fill bolt
I mean it wouldn’t hurt to just loosen the bolts holding that piece that blocking it, and slightly nudge it out the way. Then put it back in place.
So how much transmission fluid does it need ?
