2018 Hyundai Elantra Transmission Fluid Change - 3X Drain & Fill with Amsoil ATF (6Th Gen Elantras)

[@eastbayarearesident3631]

Thank you for posting this video. I used it as a guide to drain and fill my own 2018 Hyundai Elantra. For those who are looking to change out their ATF, here are some additional comments & observations: 1. @ 0:28 popping the 2 rivets and removing the manifold makes it very easy to remove the air filter box. 2. @3:00 Shift the car to Neutral or Drive to rotate the lever plate if needed 3. @03:22- Another option is to Remove the two bolts that secure the shift mounting plate (the plate that interferes with the fill plug). Rotate the plate clockwise about 10 and the fill plug will come right out (after using a socket extension to loosen it). Obviously, don't forget to re-center the plate, then re-install and tighten the two bolts after the fill plug has been re-installed. 4. Use a 24mm socket to loosen and remove the drain plug 5. I used Valvoline Max Life ATF - I checked with Valvoline directly and they said it meets Hyundai SP4 ATF specs. 6. I bought the crush washer from a Hyundai dealer parts counter - About $3 each (PN 45323-39000). Looks like 18mm ID, 24 mm OD. Buy 2 so you'll have one for the next fluid change. 7. My ATF was pretty close to black after 50,300 miles. The maintenance manual calls out ATF replacement at 60K miles. 8. I tightened the drain plug to 30 ft-lbs with a torque wrench. I contacted the Hyundai dealer about the torque spec and they told me they did not know...which means they didn't want to tell me. SMH :( 9. I drained out 3.25 quarts so I added back 3.25 quarts 10. The car runs better and I'll drive it for a bit before repeating this exercise.

Thanks for taking the time to comment. I am glad it worked out for you. Cheers! 😊

You can move the shift bar out of the way by accessing the shift/lock/release button inside the car at the shifter, which will alloow you to move the shifter out of park to any other position.

[@mitch1847]

Your diligence is commendable and you're doing what 99% of vehicle owners don't do, but 3x after just 30k miles is a little overkill. Every 30k miles is fine.

[@andy-auto-info2483]

Thanks Mitch. I understand its overkill. I did it to replace most of the old fluid with new fluid. Infact, with the lab results, I found that mixing does not do any harm to the transmission fluid. So 2X would have been just fine :)

[@andy-auto-info2483]

You can read my pinned comment. I have more information there. Thanks :)

[@Cedric_Harris]

This video was very helpful. I just drained & filled my 2018 Elantra. It has 100k+ miles, but I decided to do it anyway. I opted for the Valvoline MaxLife ATF, and so far so good. My transmission was always smooth, but if it's possible, it's even smoother now. With regard to the fill plug, I decided to file a notch in it like in this video, however I only needed to file a very small piece in order to get it out. It was very close to coming out without any filing. So if you're watching this video and you're worried about filing it down, don't be, it only takes a couple minutes. You don't have to take that much off at all.

[@giantzfan247]

Any update/issues since doing it. I have factory fluid in my 18 at 92k miles and am planning to do it this weekend.Am a bit worried so was just gonna do 1 drain and fill and than after about 2-3k miles do another.

[@cgatito3528]

I was able to easily remove the fill plug on my '17 Elantra 2.0 without filing a clearance cut. The trick was to not just pull straight up but pull it at a slight angle away from the interfering tab. By angling the plug, it looked like there was only a tiny (< 1mm) interference. I did not feel like I was even coming close to damaging the plug and only needed to pull with a slight force. Ambient temp was ~80 deg F, so warmer temps may help here. I tried putting the plug back on and it was much more difficult, so I did cut a very shallow semi circular clearance cut with the plug on the work bench. Only took about 2 minutes to file a ~1mm half moon cut with the plug out. Now it re-installs easily. Thanks for the detailed video and being a pioneer on this procedure.

[@andy-auto-info2483]

That's good to know. I tried all angles and it did not budge unfortunately. Maybe its the warmer weather like you said, ha ha. Glad it worked out for you and happy to help. Cheers! :)

[@cgatito3528]

​ @Andy-Auto-Info A few more notes: If it looks like plug has a large interference with the offending tab, keep rotating it slowly in ~10 deg increments and rechecking the interference. You'll see that the interference goes to almost nothing at 2 angular positions of the plug (located 180 deg apart). This is due to the 2 slots cut into the bottom part of the plug (also located 180 deg. apart) The slots allow more "tilt" of the plug when oriented correctly. Hope this makes sense. Note 2: I let my fluid drain for almost 3 hours after warming up the fluid with a 10min drive. I was able to get almost a gallon drained out. (~3.9 quarts) Note 3: I used Valvoline maxlife --I understand your reasons for not, though. So far, shifting is smooth as silk.

Brilliant instructional video. Best I've seen. Bright, detailed, clean, clear. I'm going to do this procedure this weekend. I'm going to loosen the vent plug but I'm not going to file and remove it. I'm going to refill the fluid in the fill hole where you checked the level, using a hose.

I can't believe I shared this video to my friends but didn't have u subscribed. 😔 I just subscribed right now. Thank you again for the wonderful video. I showed this video to few of my friends who have a same car and they are surprised how easy it is to replace the fluid. Because of how people say transmission is "sealed" and that u gotta take it to the good mechanic or a dealer. I show this video and they are surprised how easily u do it and I even let them use my extension socket and they were able to do it. I will keep sharing this video.

Thank you for the support. Appreciate it. :)

[@ahmadghosheh3104]

Very very well made video. For the fill plug, loosen the two 10 mm bolts of the shifter and slightly turn it, the plug will be free. That worked well for me. I wouldn't worry about the shifter position, just mark where it was and rotate it back to the same spot.

[@alialnajm789]

For the filling cap you can easily put the gear shifter on D by realesing gear shifter

[@andy-auto-info2483]

Hi Ali, I tried that. The shift selector was not in the way. There is another hexagon looking bolt under the selector which was coming in the way of fill plug. So irrespective of what gear you are on, the hexagon bolt does not change its position. Hope that makes sense :)

[@JJ-iw7nh]

I used the check plug above the drain plug. Not necessary to remove the air box. And not necessary to modify anything

[@andy-auto-info2483]

Yes. You can pump fluid into the check plug. I have already included that procedure in my pinned comment. :)

[@leek8079]

Amazing video , thanks so much for the detailed and easy to follow steps!! About to pull the trigger on a 17 elantra with 61k miles so I’m looking to do an ATF change asap . Will definitely be referencing this video and your pinned updated comment. Thank you!! EDIT: when checking the ATF level, you mentioned the temp needs to be 120-140°; that’s from the reading on the temperature gauge inside the car? Also, do you remember where you got the filing tool for the fill plug? I know I can refill through the level check hole, but one of the steps to checking the fluid level is to remove the plug so I’ll have to do it anyway.

[@andy-auto-info2483]

Hi Malik, Thank you for your appreciation. Means a lot. Checking the temperature of the fluid cannot be done using the gauge inside because you cannot tell. To do so, use a Infrared temperature gun (20$ in Amazon) and measure the temperature of the drain bolt when the car is at level and running, gear in P. When the temperature of drain bolt hits 120 F, you can be sure that the temperature inside the transmission and the fluid temperature will be between 120 and 130 F. At this point, remove the check plug and let the excess fluid come out. When you see a small steady stream, close the check plug and you are set! :) I feel re-filling via check plug might make it messy. And you may need a special plug to insert inside the hole. Just FYI :) I got the filing set from Home Depot (Husky tools are awesome value) - www.homedepot.com/p/Husky-Steel-Precision-File-Set-with-Storage-Case-6-Piece-707476H/207112197?cm_mmc=ecc-_- All the best!

Today I did change my 2017 Hyundai Sonata ATF I drain all the oil it is almost 4qts and then I filled. I didn't open that black socket overflow which is near drain bolt it is ok ?? and while filling it tooks too much time because the air I fill little by little If I do fast oil comes out? What is the reason?

[@andy-auto-info2483]

Hi, what fluid did you use? And did you put back the same amount of fluid in? Maybe the funnel you used was covering the entire fill hole. When this happens, the fluid does not go in easily and bubbles out frequently. It goes in slowly. For my car, I used a smaller funnel and the fill hole was wide. Hence, it went in easily.

[@DesiTravelDiaries84]

@@andy-auto-info2483 I think so funnel is the problem. When I keep straight and tight it won't goes then I kept loose then little by little it goes. Next time I will get more small. Please share your WhatsApp.

Hi Hersh, It should be the same type SP-IV. Check your owner's manual, you will find the info as well. For a drain and fill, it would be around 2.8-3.2 quarts per drain. The total capacity of the transmission should be 7.1 quarts. I don't think its changed for the 2019 model, you can check owners manual to confirm. Please watch the entire video, you will definitely understand the process. Cheers :)

[@IAmDeniseKaylee]

I posted my comment on a similar video, so I figured I'd put it here as well: 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. 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!

[@andy-auto-info2483]

Hi Denise, thank you for the wonderful input. I'm sure it will help GT owners. Yes, the methodology of drain and fill is similar but the design of splash covers and location of transmission could be different. For Elantra non GT models, we have to remove the splash covers like how I did. Thank you once again! :)

You can re-use the washer many times if you don't tighten it too much and turn it to the other side. I have done it many times in my Elantra 2008 and Kia soul 2012

[@andy-auto-info2483]

You can definitely do that if the washer is re-usable. You do get re-usable washers. Generally, crush washers are used for one-time purposes. The thickness in mm is drastically reduced once you tighten it. If used multiple times, there are chances that it may crack and the fluid may start to leak. Especially if you torque the bolt to specs. Feel free to re-use at your risk. There are chances that it will develop crack and leak. We should not ignore cheap insurance. Thanks :)

Hi, Yes manual says at 60k miles. It is okay to do it at 60k miles, but not later than that. And it also depends how the car has been driven. Severe/rash driving conditions may deteriorate the fluid quickly. Best preventive maintenance plan in my opinion is to drain/fill the fluid 2-3 times at 30k miles - this removes all break-in materials. And thereafter just once every 30k miles. This will make it last 200k miles and beyond!! :) How many miles does your car have?

I did a 3 time drain and fill becasue I wanted to get as much as new fluid in. See 23:07 for some more interesting information about this. :)

[@village_ram]

is it okay to send a dipstick down the fill port and permanently mark the cold level ( ullage ) on the dipstick before draining the fluid so as to have a level mark to refill the new fluid to?

[@andy-auto-info2483]

I would recommend you do not do that. May not be accurate because of the way the dip stick would go in.

Hi there is no filter in automatic transmission like benz have

[@andy-auto-info2483]

There is a transmission filter. Its basically a screen type filter. It is very hard to replace it. But that's not a problem, keeping the transmission fluid as clean as possible by doing regular drain and fills every 30k miles will make it last minimum 200k miles in my book. :) The filter could be a non servicable one. So don't worry about it :)

[@andy-auto-info2483]

Since there is no pan, you can't drop the pan and access the filter like traditional non-modern transmissions. Its somewhere inside and might be difficult to get to it.

[@cocourth5611]

I have a question. Would it be a good idea to drain and refill Transmission fluid once every 10k miles instead of doing it 3 times at once every 30k miles? Because if it's fine to do it, then I wouldn't mind doing it every 2nd oil change. Gets rid of hassle of jacking up two more times just for transmission fluid drain. Because this way, I can set a day where I can do oil change, transmission drain, and tire rotation all at once every 10k miles. I do oil change every 5k miles. I have 2019 Hyundai Elantra SEL and it's already at 36k miles. I plan to do transmission drain 3x on my 40k mile mark along with tire rotation and oil change. After that, I plan to do it once every 10k miles. Any input on this idea?

[@andy-auto-info2483]

That is an interesting question. Since you have 36k miles, you can do what you said without any issues. But if the fluid looks very dirty after the first drain (use your intuition), then I would recommend you do a drain and fill 2 times (driving about 50-100 miles in between). That way you can get rid off most of the old dirty fluid. If you are using OEM fluid, then 2 times is sufficient. You do not need a 3rd drain and fill. I did it 3 times mainly to replace 80%+ fluid with new and because I was using a non-OEM (Amsoil) fluid and I did not want any mixing issues (But I learned from my oil analysis that mixing fluid did not cause any damage to the fluid). But as you saw from my video, after 2 drain and fills, the fluid looked to be in good condition. Additionally, my oil analysis said that the fluid was in perfect condition. Hope this helps. :)

[@cocourth5611]

@@andy-auto-info2483 Definitely helped. On my upcoming transmission oil change for the first time on my 2019 Hyundai Elantra, I plan to do it 3 times the way you did it. After that, I might just flush every 10k. I used to do transmission fluid change on my 2003 Acura TL and it was easier than regular oil change. This one is no different. Only hassle I'm gonna have is bottom bumper cover on and off but it's well worth it because it protects the parts. I learned from your statements regarding the oil. I was close to using Valvoline MaxATF because that's what I used on my 2003 Acura TL Type-S since all it required was Z1, so MaxATF worked fair enough. But it is quite skeptical that a viscosity that works on my old 2003 acura tl would also work on 2019 modern hyundai elantra. So I'm taking your advice and gonna go buy AMSOIL OE Fuel Efficient ATF even though I have 3 gallons of MaxATF. I'll prolly save MaxLife for a different car or if I know any of my friends who will need it.

[@andy-auto-info2483]

​@@cocourth5611 I am glad you understood what I had to say regarding viscosity. It very important to get that right. I had a 2001 Honda civic myself and I was using the Z1 fluid. Thats how I knew that these modern cars use a thinner viscosity fluids. And after 3 drain and fill procedures, you are good for another 30-40k miles. You can just do 1 or 2 drain and fill every 40k miles after the initial 3 time drain/fill procedure. That should keep the tranny healthy for a very long time. And true synthetic ATFs last a long time which is good. Also, do not forget to use the level check plug to make sure the fluid is at the correct level. Good luck! Do share your experience after the change here. Someday all this info will help others. :)

Honestly, the process is easy. If you can do an oil change, you can do this. Just need to have patience and do the steps slowly. This was my first time as well and it was an enjoyable experience. 1st time I took my own sweet time to do it. 2nd and 3rd time I knew exactly what needs to be done, I did it very quickly! ha ha :) 2. IMPORTANT - I would recommend using the Level plug to check the fluid level (Making sure the car is at level). To do so, add about 0.5 quarts extra in the transmission. Use a Infrared temperature gun (20$ in Amazon) and measure the temperature of the drain bolt when the car is at level and running, gear in P. When the temperature of drain bolt hits 120 F, you can be sure that the temperature inside the transmission and the fluid temperature will be between 120 and 140 F. At this point, remove the check plug and let the excess fluid come out. When you see a small steady stream, close the check plug and you are DONE! :) Here's what happened. I did not spill a single drop of fluid and measured the fluid as accurately as possible. I added 0.2 Qts extra at the end as well. There was no issues with shifting as you saw at the end of the video and did no harm. I just wanted to check the level using the level check just to be sure. Went to a local mechanic, he checked it in front of me It was low. Had to add 0.3-0.4 quarts in order to get to the right level. He actually pumped the fluid in using the level check hole, so even that can be done to fill the fluid (It could get messy by this method, so I would stick to filling the fluid via the fill hole at the top). It is all good now. Still shifts like butter! I wonder if the factory fill was under-filled a little??? Or does the tranny fluid evaporate over time??? I did my research, it actually does not. Some websites say it does!! Any idea??? Strange - huh! :D :) 3. Some folks have mentioned that the fill plug came out easily for 2017-2019 Elantras. At the same time, there are folks like me that had bad luck and had to file in order to open. So fingers crossed! 4. OIL ANALYSIS - I received the results of the oil analysis of the sample I took from the 3rd drain. The fluid was a mixture of 65% new amsoil fluid and 35% of old Hyundai SP-IV fluid. The fluid was 100% alright without any Metallic compounds present and the fluid was in excellent condition. This means that, all the break in materials were flushed out after 2 drain and fill procedures and also proves that mixing fluids does no harm to the fluid! But a 3rd drain and fill is recommended to put most of the new fluid in and keep it real clean :) Cheers! Let me know if you have any questions! :)

By doing the drain and fill procedure 2-3 times, you get 80-90% of the old fluid replaced with new. You can check the video at 23:07 mins for more information.

I looked into the viscosity issue that you mentioned. And unfortunately, since I bought a case of Amsoil Signature Fuel Efficient ATF, the viscosity numbers are worse for the Amsoil. I'm seeing (all at 100C DEG C) Hyundai OEM SP-IV at a viscosity of 5.4, Max Life at 5.9, and Amsoil at a staggering 6.3. Old Hyundai SP-III has a viscosity of about 7.2. The Amsoil Viscosity Index also is poorer than MaxLife, at 159 vs 163. I cannot imagine how going from the much thinner Hyundai fluid to the thicker Amsoil will do anything except reduce MPG, vs improve it. And the Amsoil is waaaaaaaay more expensive. Anyone want to buy what I have left off of me?

I wonder which transmission line going into the transmission is the correct one that I can find a good tool removal area. I like the idea to drain, fill, run the engine while sticking the line into a clear bottle to catch what fluid comes from the torque converter and goes through a radiator tank or cooler, then stop when the bottle holds about a quart, add a new quart to the transmission and repeat the process a few times. A second person is needed to start and stop the engine quickly, even shifting through the gears a bit. I did this with my Subaru and it was very easy (3 cycles of the process). This way I was sure to get out a good amount of old fluid before resorting to driving again and simply mixing the new with the old. **Anyone have photos of the specific line that goes into the trans after it has performed the cooling cycle and is about to go into the trans functioning process?** By the way, bluetooth OBD2 readers connect to the OBD2 port and read to phone apps and SOME read the fluid temp. I use a BAFX reader with an app called CAR SCANNER PRO and / or ACTIVEOBD. Both apps work fine but the Car Scanner Pro connects with less effort. ActiveOBD often requires a phone restart, as in power down restart.

I did 4 drain and fills with OEM ATF SP-IV-RR. Dealership suggested to replace the full transmission assembly. I have done 4 drain and fills of the ATF, I changed all solenoids, changed the wiring harness for the TCM and changed different sensors inside the transmission, no luck! I suspect a bad TCM or software bug, or a bad Torque Converter. My last resort is a transmission replacement. What are your thoughts please?

[@andy-auto-info2483]

Sorry to hear that Husam. It looks like there is definitely an internal problem with wearing gears or torque converter like you said. I'm saying this because you changed out the fluids and replaced electricals like solonoids. Did you check with the dealer to reset the transmission software? Also how many miles do you have now and how often was this maintained?

[@husamothman1]

@@andy-auto-info2483 Thanks for your response. Yes the dealer did reset the adaptive values of the TCM. It still has the hard shift. The car is 170,000 km on it and i am the 1st owner and it is top notch maintained.

[@andy-auto-info2483]

@@husamothman1 that's only about 105k miles. Not too much and if you have maintained it well, not sure what may have happened. You did mention its a V6 engine, so a more powerful car. If you have done more city driving (severe conditions) , then it would br harsh on the tranny as well. There are so many factors that affect it. If you can manage how it is currently, then fine. Worst case, before you replace the tranny, maybe give Amsoil OE fluid a try? One drain and Fill and maybe check the difference? You never know, it could fix the issue. Let me know what you decide and what the outcome was. :)

[@husamothman1]

@@andy-auto-info2483 Yeah, I am scheduled for a discussion tomorrow with the dealership and I already ordered Valvoline MAXLIFE to give it a try. I have my suspension around a bad logic in the TCM as this seems to be a common issue with multiple cars of the same model. I'll keep you posted.

[@andy-auto-info2483]

@@husamothman1 Definitely . Good luck with it. :)

[@Roadsurfer2k11]

Couldnt you have just removed the 2 nuts and that plate sitting above the bolt to remove it???

[@andy-auto-info2483]

That is the shifter assembly. You have a good point. But I did not want to touch this because of calibration concerns. And they normally have very specific torques for smooth shifts and I did not want to risk it. Also, FYI, some people were able to get the fill bolt off easily and some like me, faced this issue. So fingers crossed :)

[@Roadsurfer2k11]

@@andy-auto-info2483 ah ok..understandable. I have the '18 GT model so hopefully mine will be lil easier to get it out. The air intake is already out lol I swapped it for a cold air intake

[@andy-auto-info2483]

@@Roadsurfer2k11 ha ha. I see. good luck :)

[@alexceja696]

That is what I did. Removed the two bolts and the plate rotates left and right and gives you the clearance to pull the plug out.

[@Roadsurfer2k11]

@@alexceja696 k thx for the update. I noticed now if precise replacement needs to be done, I would use a pencil and outline that curve on the plate, drawing on the base. And mark off each side the bolts attached to it, so i would know exactly its position put back on

Thanks for the video! What car is under the cover next to you? Looks like a really old hub cap...

[@andy-auto-info2483]

I am not sure which car that is. The tire is completely worn but the paint if the car is still good. :)

[@SecretSilopod]

Will it be the same process for the manual transmission version?

[@andy-auto-info2483]

No, for manual transmission, the process is very different. :)

[@Finite121]

Thank you for the detailed video! I'm getting ready to perform this service on my 2017 Elantra and wanted to ask about the ramps you use. I've always used my jack and jack stands when doing oil changes but am thinking of investing in some ramps to make things a bit easier and allow me to keep the vehicle better leveled. I've browsed a bit on amazon but would appreciate your recommendation. Thanks again!

[@andy-auto-info2483]

Thank you for the feedback. I used Rhino Ramps. This one costed me $30, its a good one.

[@Finite121]

@@andy-auto-info2483 I just completed this service the past weekend. I performed two drains/fill. My Elantra has over 105k miles, about over 75% of those are highway miles I would approximate. No issues so far even after performing the service well past the suggested mileage. Thank you again for the detailed video. I wanted to provide my experience with the fill plug for anyone who comes across this video later and looks at the comments like I did. I was able to remove the plug relatively easy by loosening it first and then keeping my extension in and pulling back on the plug with a little force, not much but this was enough to remove the plug without having to file anything down.

[@andy-auto-info2483]

@@Finite121 that's good to know. I'm glad this has helped you DIY successfully :)

[@MPRPETE]

When do you recommend changing the filter or is there even a filter

[@andy-auto-info2483]

There is a filter inside the transmission. It is not serviceable. Usually dealership changes the filter when transmission is hauled and opened. Changing the fluid every 30-40k miles and keeping it clean is the way to go for this car. :)

[@MPRPETE]

@@andy-auto-info2483 interesting so the dealership only services the filter when the transmission needs a overhaul?

[@andy-auto-info2483]

@@MPRPETE yeah, I know its hard to change the filter or access it even for the dealership. That's what I got to know when I asked them. They say when they do a flush at the dealership, the force at which the transmission fluid is replaced while doing a flush, the process also cleans the filter. Its basically a mesh type of filter.

[@MikeTrullAmsoildealer]

Very well done I like your analysis of everything. Yeah I'm not sure about that viscosity issue. I think there are different s p e c s just for that reason. Thanks for choosing a true chemically engineered synthetic fluid as well. Group 4 and group 5 much better than group 3 hydrocracked petroleum which the courts ruled you can call this synthetic.

[@andy-auto-info2483]

Absolutely. Thanks Mike. :)

[@miken118]

How many quarts of amsoil atf do the elantras take if I do a drain and fill?

[@andy-auto-info2483]

Hi, you would need about 3 to 3.5 quarts for one drain and fill. Better to have around 4 quarts just in case! :)

[@neto6230]

Does changing the transmission oil from this model and 2018 they use a oil filter?

[@andy-auto-info2483]

There is no easy access to the transmission filter. It's placed inside the transmission. Usually, transmission filter is not serviced, it is only replacing the fluids. You can check with your local dealership for more details. :)

[@TripDadLife]

7.5 gallons worth of changes to get 99% of the 1.75 gallons of transmission fluid to be clean?

[@andy-auto-info2483]

Are you referring to the last picture I showed? That was just for funny information. I don't think you need to do so many changes. If you plan to use a different fluid for the change, then do the drain and fill 3 times just to replace most of the fluid like how I did. You will be fine with doing 2 times as well. If you use OEM, then 2 times would be good. :)

[@TripDadLife]

@@andy-auto-info2483 I was just making an observation about the last picture yeah. I'm also wondering about how many flushes it takes to get 5050 coolant to be in cooling system if you can only drain 2 quarts at a time (with a similar 7 quart capacity) so this helps a little.

[@andy-auto-info2483]

@@TripDadLife you're saying only 2 quarts come out in a coolant drain for a 6th gen elantra? If that's the case, its a wise idea to do a coolant drain and fill twice at 60K first and then once every 40k intervals. That way the fluid will not go bad. It will constantly be rejuvenated.

[@subietech2019]

Damn, I better do this soon. I got 70k on my '18. Runs great though

[@andy-auto-info2483]

Yeah. Better to be safe than sorry!

[@SXTHGEN]

How many quarts did you have to buy? This will be the first time I will be doing this to my 2018 Elantra and would like to know how many quarts I should buy. Great video thanks for the information!!

[@andy-auto-info2483]

Thank you! I had bought about 10 Quarts. But if you are using OEM fluid, doing this 2 times should be sufficient at 30k miles. :)

[@SXTHGEN]

@@andy-auto-info2483 okay thanks, so my car is at almost 60k and I have never done it since owning the vehicle. I bought it at 24k miles, what is the difference between flush and just draining it and replacing it with new oil?

[@SXTHGEN]

@@andy-auto-info2483 also is there a transmission filter for this vehicle?

[@andy-auto-info2483]

@@SXTHGEN I would not recommend a flush. Usually, for Hyundai transmissions, they force the old fluid out and add the new fluid simultaneously. A machine does this. And all the metallic particles are forcefully pushed out and may damage the gears or components inside. You can research more on this online, you'll definitely find lot of articles. By draining and filling, there is no risk at all. And also you get an opportunity to clean all the break in materials captured by rhe magnet. Doing this 2 or 3 times makes sure you replace most of the old fluid by new. Check out the end of the video for a tiny analysis and check my pinned comment for more info. Thanks :)

[@andy-auto-info2483]

@@SXTHGEN also, there is a transmission filter inside and is usually not changed by Hyundai. It is very hard to service that and even the dealers do not do that. Regularly maintaining the fluid and keeping it clean should be enough. :)
