I have a '16 Sportage with <55k on it, and would REALLY like to service the trans, but I'm being told, "The transmissions are factory sealed and 'never need servicing'. The fluid doesn't wear out." Hmmmm... OK, so I've been messing around with cars for 50+ years, and I am an AVID BELIEVER in synthetic lubricants (Amsoil in particular) and the service life, friction/wear protection, etc. However, even the best synthetics have a service life, and after that they must be replaced. So, the way I see it, having a "sealed transmission" is an absolute guarantee that IT WILL FAIL long before it would if one could service it regularly. So here's my questions (I know...at last!): Is there any way to change the fluid? A drain plug/fill plug that the dealers won't tell you about? Fill quantity after it's drained?
I own and maintain 4 vehicles and this is the only one with a trans I can't service...and it's DRIVING ME NUTS!!!😖 Is there any hope for my sanity, or am I beating a dead horse??
Any help from anyone will be greatly appreciated! Thanks!

Look on YouTube for How-to. I changed trans fluid, diff and transfer case to Amsoil at 75k. No dipstick, so you have to measure what comes out and put the same amount back in. Have about a gallon on hand for the transmission service.

Sorento is similar. The drain and fill are on the back side. For me, loosening the plastic sight hole just made a mess. I just changed the wife's Avalon trans to Amsoil. It is also "sealed" and a totally different experience.

There's a YouTube video on it. It's put out by an Amsoil dealer, but so what. It hits the touch points you are after. Measure what comes out, because that's what goes back in. There's no sight glass or other way to determine when it's full. It takes about a gallon for a change.
