Yep, that's how it it's supposed to be done with our Kia. Their FSM says to warm the fluid to 140-160F; get the vehicle perfectly level; pour 3/4 quart into the fill port; and when there is a 'thin, steady stream' of fluid running out of the check port with the vehicle running, the level is ok.
Warning! Start of useless rant.
Personally, I've never been able to find one single good thing about replacing the dipstick with this bizarre, convoluted, and subjective procedure. The automakers apparently believed that the dipstick was allowing DIYers and careless pros to mess up a transmission by doing something wrong. Well guess what, many of us are still going to maintain our A/T fluid, only now they've made it much more difficult and error-prone. And I also believe that even techs are going to occasionally mess up this level checking as well. And sorry, no dipstick available to do a quick second look, if there's some uncertainty about the level being correct. Just button it up and send it back to the owner (who also isn't able to easily check the level).
There's no way I'm going to do this idiotic level check, unless I'm forced to. I did a simple drain-and-fill on my Kia, with the fluid at the same ambient temp - four quarts (carefully measured) out the drain port, and exactly the same amount back in through the fill port. On my Daughter's 3i however, I drained without carefully measuring, filled approximately the same amount back in, and then used the Mazda FSM level check procedure to check the level on the DIPSTICK. Topped off a bit, and then checked again on the DIPSTICK the next day, to make sure everything was ok. And this is what they're taking away from us :screwy:
Well, that concludes my useless rant, which serves no purpose other than for me to blow off some steam :wink:
