2021 Hyundai Elantra transmission fluid change

Without much luck finding decent information online for the 2021 Hyundai Elantra as far as servicing the transmission, I decided to make this video. Other videos claim they cover the 2021 and above, but they do not.
Starting with the 2021 Hyundai Elantra, the transmission was completely redesigned, which renders any information or guides for 2020 or earlier models useless for this car.
I hope this guide is useful in answering most questions as far as servicing the transmission of a 2021 Hyundai Elantra.
If you choose to service your transmission on your own, you are doing it at your own risk. I am NOT responsible for any damages to any vehicle.

Just did this today, 3 qts exactly came out. Can't believe how much the dealer is charging for this service. Took 40 minutes using this video. Great job documenting it for us

[@drnapalm7605]

The reason you want to open or make sure you can open the fill plug first is to ensure that you can fill it back up. You dont want to open the drain plug, empty out the fluid, only to find you cannot open the fill plug

[@kevinhaskins6619]

I just drained mine and got 3-quarts exactly to drain without dropping the pan. Mine had 53,000 miles and the fluid was dark but that probably means exactly nothing. The drain and fill plugs are 24mm and the process took about an hour. I have four more quarts that I bought and I'll probably drop the pan at 100,000 miles and change the filter with that one. I also put them on the scale prior to filling and I didn't expect weight to be a good indicator because the wear components are dissolved in the old fluid. Measured at the same temp, and the same volume as measured with a 50mL syringe, the dirty fluid was about 30g heavier for the same volume.

[@bobg3221]

If your fluid was dark, then yes it meant that it was dirty and it needed to be changed. I would never attempt to do this not on modern vehicles the old vehicle yeah drop the pan change the filter filled up with fluid run through the gears. you’re good to go, I’d rather go pay Hyundai 400 bucks to go and do this and hook their system up knowing that I have record that they did the service and not myself filter needs to be changed and cleaned as well. This is why they charge the amount they do there is a reason for this , but if your fluid was dark, then it was time for a change. I’m only wondering how dirty mine will be. My sonata has almost 82,000.

[@johnscerbo130]

I’ll be doing weekend the dealership wanted 310 dollars to do this. They told me it would be a drain and fill. I purchased the oem fluid on line for 12.50 a quart. I would do this to simplify and accurately measure the fluid…. Use a new drain pan. Pour the old fluid in to a new I gallon Rubbermaid pitcher and mark a line on the side of it. Clean the pitcher and pour new fluid back into the pitcher at the exact mark that was made. FYI just my 2 cents on this procedure

[@Onlyinbean]

What website did you buy it on?

[@RobertGolds-yf1ix]

Great video… But I would like to add that you can use a catch pan with the measurements marked around it instead of going through the procedure of pouring your old transmission fluid into the bottle

[@lonzo1kk]

I feel my speed slip when it starts to slow down around 10-9mph so I’m guessing I need a fluid change. Do you have the link to where you got the parts from by any chance? Like for the oil , seal , Etc. ??

[@HiFiInsider]

I bought the service manual and all is good. Manufacturer maintenance schedule is to protect the manufacturer, not the owner. 100K for first CVT fluid change is crazy. I do recommend using OEM Sp CVT1 fluid.

[@renedelafuente123]

I have 2020 Hyundai Elantra sel and I'm guessing it's almost the same as urs. What was mileage when you did tranny fluid change? Thanks for the video

[@cousinjohncarstuff4568]

Had oil change and trans service at the dealer, and they claim the IVT trans does NOT have a filter, even though I showed them the part #.They claimed the trans would have to be torn apart to replace it. Does not appear you had to do that for filter replacement....

[@Onlyinbean]

What model do you have?

[@robgoss8187]

Thanks for the video just bought a 2023 Elantra. Do all my own service. So I was going to drain mine into a clear tube I got at home depot that holds 5 quarts measured in half quart increments then put in exact amount I drain out in lieu of using the level check plug on side of trans with trans hot and car running. from what I’m seeing in multiple videos is between 3-4 quarts. My question is how dirty was the fluid? Would you agree with doing it every 40k instead of 60k since your only exchanging half the fluid. Or did you do two drain and fills couple miles apart? Thanks again

[@TechMaxWare]

I would say 45k is a good recommended mileage to change the fluid. Mine was pretty dirty. Now that might have something to do with it being the first fill in the car with it being brand new, yet typically with CVT type transmissions, the recommended is 45k. I only did one drain and refill which is what you saw here, simply because the fluid itself is stupidly expensive. Probably another reason I would recommend every 45k to try and keep cleaner fluid in it.

[@onthejob9153]

@TechMaxWare I work as a marine technician and I'm more than capable of doing this myself ( Especially after watching your video) but I was just wondering will it affect my manufacturer warranty?

[@kalani1987]

Dealership does not have to know you did this service. However, draining at 3k miles is too soon. I would do it at 30k

[@chrispirozzi4206]

If possible, could you write the P/N for the filter and gasket in the description? Also , the quantity of transmission fluid used. I heard 3.25 quarts. Didn't hear anything about P/Ns for them.

[@cousinjohncarstuff4568]

I was hoping to see a sample of the old and new fluid. I would check the Owners book for transmission fluid capacity....

[@TechMaxWare]

As stated in the video I did work with service techs, which is where I got my fluid from. Yes I did also reference the manual. The fluid was dirty, so I can confirm everything 45,000 mi is a good mileage to change the fluid. I agree there should be more documentation about this, which is why I made this video.

[@drnapalm7605]

There is 0 documentation on this procedure as well as fill quantities for the IVT

[@bobg3221]

Damn, a 2021 Hyundai ELANTRA the gaskets leaking not bad? When I do the oil change on my 2021 Sonata, mine is bone dry there’s no oil or grease or grime at all

[@HowaAbd]

شكرا على هذه المعلومات الثمينه لقد استفدت منها كثيرا... اتمنى لك النجاح الدائم..

[@kevinhaskins6619]

Thanks.... how dirty was it inside the pan and did you peel open that filter to look for debris?

[@TechMaxWare]

The fluid was pretty dirty. I’d say I’m glad I did this when I did. I did not open the filter but do recommend changing it every time, especially with dirty fluid.

[@matrout61]

Can you share what the torque spec is for those trans pan bolts?

[@johnjohnson9980]

Didn't the transmission fluid pan have a drain plug ?

[@bostonman8347]

Is the seal the same as the ring snap?

[@johnjohnson9980]

Wow the filter is underneath the transmission drain pan -- really. 2017 Elantra is buried in transmission requiring full teardown.

[@almostoem]

Is your car running fine post the transmission fluid change?

[@TechMaxWare]

It is running fine, haven't had any trouble. I'll probably do an update video before too long. Need to be doing more with my channel, but life lol.

[@ahmedabdullah2531]

How many liters take with filter ?

[@aaroncollins1187]

Does any programming/ coding need done and reset?

[@TechMaxWare]

Not to my knowledge. I've driven now 15,000 since this change without issues.

[@petedif7864]

You missed the 2nd cannister type filter

[@TechMaxWare]

How many comments have I had to reply to stating there is no second filter on this transmission?

[@petedif7864]

When I plug in my Vin, 2 filters pop up on the parts list , I have 2020 elantra se with smartstream ivt

[@Onlyinbean]

Anyone know the transmission seal code?

[@raymondrobinson3353]

Also what kind of ramps do you have I would like those over a jack and jack stands

[@TechMaxWare]

To be honest, I've had these same ramps for over a decade now, and they were my fathers before, so I'm not sure. I think you can get a set of decent ramps from Walmart though, or other Auto stores.

[@drewpeacock3798]

Do you have to change the filter?

[@TechMaxWare]

I would personally recommend it.

[@dontcryboutit]

Have to take the whole transmission out to change the filter and take it apart Goodluck

[@bostonman8347]

@@dontcryboutit I heard from another mechanic online that the filters only filter out big particles and thats its unecessary could cause more damage changing it.

[@crimsonpearl4686]

Why??? The tag clearly states "do not change the oil"! By doing this, you are now at risk of voiding the warranty! The manual ALSO states the same...."no check, not service needed." You're crazy dude!

[@TechMaxWare]

I honestly cannot tell if you are being sarcastic, but more power to you. The manual clearly states that you need to change the fluid every 60,000 under "abnormal" driving conditions, which if you read those, are most folks driving conditions. This is a tactic used by most auto manufacturers now days to discourage necessary maintenance in order to wear your car out faster, in some cases forcing you to buy a new one or charging you for expensive maintenance costs. If there are moving parts under such a load like your transmission, you need to replace the fluid. I'd urge you to do some more online reading on this and take better care of your car.

[@crimsonpearl4686]

You're kidding me, right?! The bright yellow label is right in your face, clearing stating "WARNING, do not change the oil". NOT bring sarcastic, just trying to save you from warranty issues!@@TechMaxWare

[@crimsonpearl4686]

@@TechMaxWare There is actually a sticker on the transmission that states not to service it. Because of this sticker physically on the transmission, the dealership and/or technician refuses to touch it at all. Not only have two different dealerships refused it, two different private shops have refused it for being too "new" and keep referring me to have a dealership do it because the technical specs haven't been released yet.

[@Onlyinbean]

@@crimsonpearl4686 The manual says 60k for severe.... most cars go under severe anyway and by the way after 100k you are supposed to follow severe schedule... all manufacturers say not to touch it but give mixed info and guess what ALL mechanics tell you to maintain the fluid!!!
