I just purchased a 2016 Hyundai Azera Base with 124,000 miles with an Auto trans last week and am not sure if the transmission is shifting normally when it downshifts during deceleration. When going under 1k RPM's it jumps up around 200 RPMs when going down gears. When I put the car in tiptronic it once jumped from 3rd to 1st. Is this normal behavior? Not sure whether the ATF has ever been replaced, and was wondering if I should do a small ATF change and replace a few quarts of fluid (maybe not a drain the fluid fully) or not do it being it's got 124k miles.
Thank you,
So the only way to check is by removing the pan or unbolting the drain plug?
There should be a fill plug higher up on the transmission where you can take a sample of fluid.

Automatic transmissions aren't like manual transmissions. You can't get all of the fluid out of an automatic in one sitting. Only what's in the pan you can change.

If it's never been changed, I would probably leave it, Hyundai have weak automatic transmissions, and the fluid is designed to last for 60,000 miles. You might take a small sample and judge based on that.
Is there an easy way to take a sample, or I have to take from the drain plug? What am I looking out for in the fluid? Metal shavings? Is there any circumstance you would suggest changing a bit of the fluid the fluid, or it will probably make problems worse if there are?
It depends on the specifics of your car. I'm assuming it's a "sealed for life" car, so there's no dipstick. If you do change the fluid, you may cause it to start slipping. Look for grittiness in the fluid and smell it. If it smells burned, leave it. Grittiness means your clutch packs are worn out. It should be a darker red with no grit.
Thanks so much for you all your help! I appreciate you taking the time to respond. Correct. It is a sealed lifetime trans with no dipstick. So the only way to check is by removing the pan or unbolting the drain plug? If theres a plug, can I just remove it for a second check? Is there anything else I have to do when removing the plug? (For example opening another bolt someplace up top so there's air coming in from the top?) Never done this before so I want to make sure I do it right.
