The fluid level check is done with the ATF at a specific temp range which is determined by using a scan tool to get the live data from the sensor. The engine is also at idle when the level plug is removed to check, not stopped.
Hi, thanks for posting. I have a 2011 Sonata hybrid which has a very similar drivetrain if not exactly the same as the Optima, and I will be doing my first drain and fill shortly. It seems to me the only way for me to do it is the way you demonstrate in this video because the HPCU is in the way of the actual fill hole. I wanted to know if any substantial amount of fluid was lost while doing the fill using this method, or if it all went in easily without a mess, and if the transmission has been shifting normally since you did both drain and fills. There is no dipstick so the only way to check the level is to see if a stream trickles from the port in which you filled it, which I don't like. I just plan on replacing the exact amount of fluid that I drain out. Any other tips you can share now that it has been driven a while with the 2 drain and fills? Thanks.
+sonatahybrid driving and shifting as normal, knock on wood. IM glad you replied so other sonata owners can be confident in this video being related to their cars. no fluid was lost during this method of draining and filling... if you have the little nipple extension, the fluid actually "drops" into the transmission, So technically the only place it has to go is into the transmission versus coming out. This drain and fill method is actually pretty common, its usually how manual transmissions are done as well as axles. its pretty ingenious to have a hole in a perfect spot that will drain out excess fluid when there is too much, if you think about it. heres a link to the tube i bought at walmart: www.walmart.com/ip/FloTool-Transmission-Fluid-Spout/16889149 i just removed the tube and stuck it onto my small funnel. When i did the drain and fill to my mom's kia soul 2 liter, she said that her car feels better... i have the 2nd drain and fill coming up for her car, i wanted to make a video of that to post but my son decided he wanted to help so i wasnt able to get a good video of it. But when i do the 2nd drain and fill, maybe i can do a video then... nice thing about the kia soul, is that its tight underneath, but you can do an engine oil and transmission fluid change without putting it on ramps. i hope any information i posted helps out.
+honhon05 Thanks for getting back to me so quick, it is appreciated. I do all my own maintenance on my cars and only use Amsoil in them, and actually just changed the oil and transmission fluid on my 2015 Odyssey yesterday, but through the dipstick tube. All previous vehicles I have owned had a dipstick tube/filler port and this is my first vehicle with a "sealed" transmission, and the traditional Sonatas have a very accessible large filler port up on top. Many owners think that just because the maintenance schedule from Hyundai doesn't call for a transmission fluid change that it is "lifetime" fluid. Their powertrain warranty covers up to 100K and then you are on your own. I don't care how good the fluid is, heat and wear have to break it down over time so a few dollars spent now is a good insurance policy especially since I plan on keeping it past that 100K mark. I have the exact same funnel as you and a 3/4" O.D. tube, I hope it works.Thanks again for posting sir and will let you know how it goes.
+honhon05 Hi again, I just completed the drain and fill with Amsoil and it was easy. I had to go get the same type of funnel tube you bought, as the one I used on my Honda wouldn't fit. I plan on doing another drain and fill next week to get more fresh fluid flowing. I documented it with pictures on the Hyundai forum here: www.hyundai-forums.com/sonata-all-hybrid-models-yf-lf/445201-transmission-fluid-change-video.html#post4013881
+sonatahybrid cool thank you again for responding and i am glad that my video was able to help you. and i checked out the link you posted, thank you very much for spreading the word on my video/channel. it helps a lot with getting views etc.... also i know how good amsoil is and such, my only reason for not using amsoil is because its so hard to come by without just ordering it off the internet, and if you find it locally, its usually an arm and a leg. i basically chose valvoline synthetic because its easy to find at wallyworld and my grand father always used valvoline, so im a little partial to it. when i did cam shafts in my focus a few years back i used valvoline conventional during the break in and had good results. thank you again and come back soon!
+honhon05 I forgot one thing that may help. When I took out the drain plug, the fluid shot out with such force that it splashed a lot of the hot fluid outside of the pan, even though I lined up the flow with the center of the drain pan itself. Next time around I will see if I can get a bucket under there to avoid all the splashing. 140 degree fluid hitting me in the face and arm wasn't too much fun.
Hi thank you for the tranny vid! I have a Kia Optima 2012 hybrid,Automatic! It’s giving me problems with what it seems the transmission it will like get stuck in gear and the rpm will go up and it does it also when I’m slowing down it just started doing that out of nowhere is there a sensor in the transmission or any ideas of what the problem might be ??

what's the size of the tube that fits the overflow hole?
Maybe 3/8 or so
What type of oil?
