Changing transmission fluid on a 2014 Kia Optima/Sonata

[@DanielWraps]

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 KZbin 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.

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.

[@dearboy05]

After the first replacement assembly didn't work, why wasn't troubleshooting done on all related circuitry?

[@aaron1576]

@@dearboy05 the pinpoint asks you to look for any breaks in the harness including the jumper harness inside the mirror assembly, if there isn’t any breaks then the conclusion, without any set DTCs, is to replace the mirror assembly. The modules are not serviceable by normal means and the circuitry inside cannot be ohms tested without breaking the shell.

[@DanielWraps]

the Optimas up to 2015 have been known to have pretty unreliable power mirrors. Mine had to be recoded so many times. that particular dealer wanted to charge me every time after the 2nd time and by the third time I requested them to replace the mirror assembly because it was within that B2B warranty period and it took dealing with Kia Corporate to get them to change it. They actually sent me down to a different dealer 10 miles away and never saw the issue again. Kia has come a very long way. The Stinger is an incredible car with a few mods.

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?

[@ddb1143]

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?*

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.

[@theoffroadingmechanic]

When I was at Hyundai we changed the fluid every 50k kms they say it's life time fluid but it really isn't. This was actually a friend's car not mine. We get complaints about the transmission delay shifting slipping right around 100k but those are from people thinking it is lifetime fluid.

[@uptownsamcv]

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...

Haven't seen a filter on these trans and I have taking the valve body out to replace the harnesses for the updated trans temp sensor. Seen them start having delay engagement into drive at just over 120k kms and just pulling the fill plug the fluid is black and can see sparkles in them. Or on the hybrid such as the yf slipping or delay engagements and doesn't seem the fluid gets changed much on them.

I'm now using Aisin full synthetic SP4, $10 a quart bottle on eBay, since local dealer really not interested in selling me Hyundai fluid. (Their price is 50 USD a quart!!!) I still kinda feel the manual tricked me- it says change every 96000 KM under severe condition, but mine starts jerking really hard around 40000 KM when shifting from second to third in cold start, and the fluid is not red any more, LoL.

Does your Kia forte have a metal oil pan on the bottom of the transmission rather a plastic or some older ones can have a metal one on the side? Yours might still have a dipstick.

[@6atlantis]

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.

[@theoffroadingmechanic]

This is a non turbo but you don't need to take the intercooler pipe but you will need to take off the intake for the airbox should be just 2 10mm. And the fill is just right there by the battery. Just don't fill it while the level check cover is off cuz it will just pour out of there and not really fill it. The valve body sticks out a bit from behind that cover and kind of directs the fluid out the check hole. I put the level check back when it's just slow trickle or a slow drip is fine.

[@6atlantis]

@@theoffroadingmechanic sorry I misspoke, I meant disconnecting one of the two coolant lines to the transmission not the intercooler when filling so it doesn't take forever. And yes I understand the whole process I'm just really nervous about when to "call it", it seems like you let yours come to more of a slower trickle than in some other videos. Thanks for the info and the video I appreciate it.

[@theoffroadingmechanic]

@@6atlantis no worries, if it's still flowing out quite a bit then it just means it's still over level it is just a level check. There isn't any coolant lines other than the oil cooler lines. Unless you have a model where they slapped an oil cooler in front of that plastic pan and blocking the level check slightly. But disconnecting anything won't help in filling and I wouldn't rush in filling just pour a steady stream so it wouldn't back up and make a mess and you should be fine.

[@6atlantis]

@@theoffroadingmechanic there are two transmission cooler lines under the battery, forward and to the right of the fill plug, right at the positive lead to the starter solenoid.

[@wozzywaterfield5913]

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

[@theoffroadingmechanic]

If your sticking a funnel into that fill with the rubber hose sticking out beside it won't really help fill it you will either get trans fluid coming out of that and making a mess. You can slowly pour it in so it won't back up in pressure like what I did. Or remove the level check but if you pour to fast it will spill over the valve body behind that cover and out the level check misleading you to thinking it's full.

[@penguinkernel]

Don't leave the level check off, it wil spill. Your have to pour slowly or use a funnel with a hose attached (got from autozone). The alternative is you disconnect the cooler line to allow air to escape. If you use the funnel with hose you can apply pressure on the hose so it seals and pour slowly. When it burps, it will burp upwards from the funnel. Otherwise, it will burp around the port and spill. The next time I do this I am going to do a regular drain and fill, but then evacuate another 4 quarts from the cooler line while the engine is running while slowly filling as it is pumped out. This will allow the whole systems fluid to be replaced.

[@theoffroadingmechanic]

Kind of hard without having the car in front of me. When you say the rpm goes up and not go anywhere is it slipping in gear or it's just not up shifting at a high rpm? If you haven't changed the fluid and it's the first time changing it then it making it worse is all the clutch material that was in the fluid that's helping it engage the clutch is probably gone and the new fluid isn't helping the clutches do it's job.

[@selnun2707]

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

[@theoffroadingmechanic]

There shouldn't been any sign of needing to change the fluid. It should be a regular maintenance thing. If you change your engine oil as a regular maintenance. It's like saying should I change it when the oil pressure light comes on or if it starts making noise. If your coming to a stop and it stalls or about to stall I would check to see if the throttle body is dirty. After cleaning will need to do an adaptive relearn. And if it is a Hyundai or a Kia they all use the same 2 wire inductive pick up crank sensor and the magnet gets week over time and loses crank signal when you slow down. Doesn't usually cause a check engine light or set any codes.

If you are confident you are able to do it by all means you can give it a try or you can pay someone to do it. But doing it the first time you will know for next time.

[@gthomas4587]

So 4L is enough?

[@theoffroadingmechanic]

You will need at least 5 bottles. Takes over 4 litres

[@komitata1]

No wonder why is oil burner😂

[@imadhondata5228]

How many litres for regular drain and refill ?

[@theoffroadingmechanic]

5L should be more than enough but good to have some extra just in case.

@@theoffroadingmechanic for hybrid sonatas and optimas or just gasoline sonatas and optimas with 2.0 or 2.4 engines ?

[@theoffroadingmechanic]

@@imadhondata5228 Just gasoline the hybrid is going to be different since it has an external electric oil pump rather than an internal one that's driven by the engine on the gasoline version and the pump doesn't operate unless in drive or reverse common failure for the pump to go when it doesn't make pressure anymore but on live data it shows rpm and the control module that's hidden behind the fender liner where water gets to it. Also the hybrid has an oil cooler if I remember that blocks off the level check mounted on the front oil pan. So definitely going to need a shop manual for capacity for a drain and fill and also see how much comes out of it when draining it.

how many quarts

[@theoffroadingmechanic]

5 is more than enough for a drain and fill. Good to have a little extra just in case.
