Changing transmission fluid on a 2014 Kia Optima/Sonata 

PLEASE READ; DON'T SKIP Just some very friendly advice and I mean absolutely no disrespect, but you missed identifying some critical parts to this process. Please make sure your identifying the torque spec for the drain bolt, making sure people understand they should be using a new drain crush washer to prevent future leaks, checking the fill bolt o-ring for any kind of cracks or damage, making sure to only tighten the fill bolt just lightly since its just hard plastic. Don't just put in the same amount of fluid that you took out because it could have been wrong from manufacturing process. The transmission temperature should be around 140 degrees F to service it. Once new fluid is in, you have to shift through gears pushing fluid through the trans, driving it and rechecking the level port to make sure enough transmission fluid is in it. I could go on and on and on. All I'm saying is we have an obligation as experienced technicians to make sure we are including all steps in these processes so people can make sure they're doing this the right way otherwise they could damage their transmissions which we both know are extremely expensive. Everything can be found in KGIS and for $18 for 72 hour access to download the whole manual it's really worth the cost! Yesterday I had to service a 2017 Kia V6 AWD and there was no video on RU-vid when I was hoping to find one on the Transfer Case fluid replacement procedure. It's different after the 2015 model year. They aren't the same, so I went on KGIS, paid $18 for the 72 hr access. Saved the whole manual as a PDF to my computer and access it anytime i want. It saved me hundreds of dollars instead of going to Kia.

A running commentary like this while working in your garage is fine!

I like these home garage maintenance work videos. thank you!

Enjoyed the short story from the dealer ! Have a nice day sir !

Nice video Glad to see the process Keep it coming. Thank you

That’s not ranting that’s truth. Customer expects you to fix it first time around unless it’s something they know about like if it’s a pesty intermittent issue but other than that I tell guys don’t guess or think you know what it is make sure you know what it is and TEST, TEST AND TEST. Then all is happy especially customer and that’s what you want a returning custy that confides in you and your abilities. Good seeing you again brother in arms. God bless you

I had a warranty job that has came back numerous times for mirror adjusting issues. First time was the R/H mirror motor was bad, second time the L/H power fold stopped working with no codes showing, was suppose to replace the whole assembly but the part that came in also had the same problem, no codes still, got another mirror assembly for the L/H side and still didn’t work but it finally gave me a code and pinpoint pointed me to the door module. This poor guy has been back for the same issues so many times and we can’t do much until the problem truly shows itself.

Did mine last night. 2017 Kia Optima same set up. Did not go this easy and I was following the steps on AllData.

This ... Saturday.. im doing this ..same car ...thank you ..sir

Was wondering where you prefer to jack up the car when putting it on stands? I haven't had to jack up the rear yet, but on the front I want to jack it up where the LCA meets the subframe but my jack isn't low profile enough to reach it at the right angle without blocking the pinch welds. Where would you recommend, or should i get a lower profile jack to reach that spot I mentioned?

Really enjoyed p-tech and Hy-tech videos. Too bad p-tech doesn't make videos anymore. I'll have to rely on hy-tech now

Hello. Was this your first time changing the transmission fluid in your car? I have a 2014 Optima SX Turbo with 55,000 km in Canada, and I haven't changed the transmission fluid since I bought it new.

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?*

When I went to fill it back up fluid kept Comming out of filler spot felt like something was blocking it

Why would my 2014 Kia stop acceleration while the car was still running?

Thank you for making this video

i do mine at 50K here in south florida and it's still bright red, wow! that looks awful

So just removing the level check plus and letting it drain removes the excess fluid? And then you just screw the plug back in when it’s at a trickle

Is measuring the old oil and replacing it with the exact amount fine?

Hi, how long did you have the leave the car running before you reached the level hole stopped dripping?

I did one on a 2012 the other day. I just drained it while cold than filled it while the front level check hole was removed and until fluid started coming out of it, I only used 3 quarts. after it was warmed up I opened the level check hole and nothing came out. car has 160,000 miles. I'm going to do monthly drain and fills until the fluid looks good than drain and fill it once a year after that...

you cant film at work anymore?

Is it the same procedure for hyundai accent 2014 usa version that uses the automatic transaxle a6gf1 ???

Hola qué tal. Me gustaría saber qué pasa si se pasa de aceite la transmisión??;

Is there a gasket on the pan to change the transmission filter where do you make your own gasket with a gasket sealer? And is the filter right behind the pan.. When I pull the pan off?

Hey buddy quick question I just got a 2012 Kia Optima the HID headlights will not focus inwards I tried adjusting them with no resolution I was told that maybe the reflectors are worn out I was wondering if I do the halogen replacement headlights are they plugged and play? Is the main pigtail going into housing the same? Any help would be great thank you

How to know what is the correct fluid for the transmission? Have some type of numeric name like the engine oil? (like 5w30)

You forgot to put the automatisch transmission in drive a few seconds before checking the oil level

At the end of the video why did you let the tranny oil come out again?

Did they make you take all the videos down that you recorded at work also?

Hey I'm from united Arab Emirates🇦🇪 I just buy kia optima 2013 hybrid US spec it's on 128k miles right now vehicle is perfect running and smoothly gear shifting without any problems, also I recently changed engine oil 5w20 which recommend dealership, may I know should i change transmission oil or what types of fluid can I use? There is sealed type of transmission guys😢

What are signs you need transmission fluid change. I have the same year make and model silver gold color. But sometimes when I drive, you know while you have your foot on the pedal and it sound like the engine stoo or it kind of stall and then you put foot on gas again and then it comes back to hearing the engine. It sounds like transmission. Mines is a little over 100,000 miles

Would these steps be the same for a 2015 optima? It looks like the same, but not 100% sure

But what size did you use to take off the fill plug screw? 12mm or 14?

Doesn't hyundai say the transmission fluid is lifetime? I know kia does

Hi sorry I wanted to ask you a question looks like you know about these cars, I own a 2011 KIA optima SX with 177k miles, recently I have been having less power on it ive noticed that its RPM go up but car doesn't go anywhere and sometimes if I let go off gas pedal rpm stay stuck and car keeps going until I tap gas pedal seems to unlock it. I took it to local transmission shop adviced to replace fluid and now car feels worse. Any suggestions I really appreciate it. Also hear a whining when I accelerate from a stop. Thank you

Should I remove the breather hose near the fill port ? It overflows unless the check level cap is off

Good video. Thanks for posting. I noticed this is a Kia and you used Hyundai fluid. Would the reverse be OK as well? I have a Hyundai I want to drain and fill, and I have some leftover Kia fluid that I used in my 2016 Sportage - Kia SP4 M fluid. Do they both use the same formula? In both manuals, the description for replacement fluid is exactly the same, by the way. Thanks for your time.

I have a 2014 Kia Optima (currently 170K miles) that I bought used (it had 124K miles) and I am thinking about doing this soon. Should I use any additives after replacing the fluid?

Hey what happened to the all the awesome videos you had from dealership fixing Hyundais. They were super helpful as it’s really hard to find DIY videos on Korean cars

How are those Uniroyal tires doing? Why did you put those on last time? Were they on sale or maybe he needed something economical but good?

I have a 2015 kia optima sxl turbo is there anything different from this that I would have to do

Question: what is the socket size for the top breather bolt?

I jave 2016 optima when first time to change it? At what miles

Can I ask where are you allowed to dispose of old car parts in Vancouver/Burnaby? I was cleaning out my parents garage and i have stuff that goes back 20 years if not more 🤦

I have a 2011 forte that has a slow drip. I am wanting ti check thr fluid level and top off. Docyou check the level while the vehicle is running in park? It appears so from this video I just wantvto verify first to make sure I dont pump out more fluid than just the access. Thanks in advance, great videos!

thank you

Does this work for a 2011 Kia Optima Automatic Transmission ?

Did you have to takeoff one of the intercooler lines so refilling the trans Didn’t take forever? Also I would’ve liked to see when you put the inspection cover back on, when exactly you consider a slow trickle so I could have a good idea.

Another question can I do this myself or do I need to take it to the Kia dealership

if change the auto filter , do we need to take out the whole gearbox?

Hey Juno glad to see you work on Korean vehicle again! Just wondering does the filter need to be changed on these sealed trans? Or just fluid change is fine? I see many people follow the manual and think trans fluid is life time fluid and their trans broke around 100k miles.

It appears that there is not room in your garage for a lift but wouldn't ramps make things much easier? As for work, your videos did not reflect well on Hyundai and Kia, regardless of what you want or intended. Good luck.

Thanks a lot cuz I really needed this but, what kind of the transmission oil did you use cuz i have a sonata 2016 2.0L

same procedure on the hybrid?

When should I change gearbox oil?

Would love to see a tool box tour. Nice box you have over there, is it Snap On.

so car running in neutral, check oil level!?

how much oil needed?

Que aceite usaste?

How many litres for regular drain and refill ?

how much oil?

I have that same car and I have a question about my car

So 4L is enough?

Are you in California? Man I need a new mechanic!!

Hey guys please make sure you disconnect the one of the transmission cooler lines in front of the battery because when you go to fill the fluid from top you will make a mess everywhere and that will cost you money… This guy does not state that in his video 👎🏾👎🏾👎🏾👎🏾

how many quarts

No wonder why is oil burner😂

If there were NO leaks couldn't you just replace the exact same amount of fluid you drained out ???

Good stuff
