Yes, A friend of mine just mentioned this
He does this with all 3 of his cars. He said it's the easiest way to do the tranny fluid changes.
It's so much better than the old method and way less mess. I was doing good on the 2019 until it came time to fully drop the pan. Then I bumped the exhaust and dumped what was left in the pan everywhere....

Never have understood why most automatic transmissions don't have drain plugs and don't use spin-on filters accessible from outside the unit.

As Jazzer said, it's bean counter driven. Plus, there is a LOT of people the NEVER check their fluid level, let alone bother to have it changed along with the filter. You're lucky they voluntarily change the engine oil. Pretty much the rest only gets changed when they have to to get the vehicle to pass inspection or the vehicle is dead in the water and they need back up an running.

My credo
If you don't have time to do it right will you have time to do it over?
Slightly overfull is likely OK, if it's overfull enough to contact rotating parts, the fluid will foam up and when foamed up fluid gets sucked into the pump major failure is likely.

I wouldn't remove more than an 1\8-1/4 quart at a time.....it doesn't take much to drop or increase the reading on the stick......since its running good i would just go 1/8th of a quart at a time then drive it for a day or two, see how its doing , where your level reads etc

I like to check my level after I've been driving around for a while and tranny is at operating temp, good and hot, as opposed to say starting the truck in the morning and just waiting for the needle to read engine heated up to normal temp....youll get slightly different readings....On the dipstick jt says check at operating temp, so that's the trans not the motor so make sure the trans is good and hot

They want you to do that with the new Ranger as well but you have to check the fluid level under the truck and the cap and dip stick are 'conveniently" next to the exhaust pipe. I wore gloves but the exhaust still found an uncovered section of flesh on my wrist. The remaining scab is finally gone a few weeks later and I have a nice little scar as a memento. So, I have to find better gloves, like nomex flight gloves or a different way to do it.

My 2007 4.0 Mustang didn't even have a transmission dipstick. So there was no way to even check the fluid level at all. DUMB!

You know someone never checks even their oil level when you look at their front tires, and the outside corners are totally gone, and they keep driving it. Chick I know where I live is one of those. Was sittin in my garage smoking a big fat C-gar, and drinkun bourbon, and saw something shiny on her driver's side rear tire. It was the steel belts, showing all the way around the tire. Left her a note telling her it was FUBAR. Next thing I know, a dumb friend of hers is over with an electric compressor trying to air it up. I pointed out the obvious, and he said, "I know what I'm doing, I work at O'Reilly's". Okay then. Carry on. Really dumb!

My sister borrowed my Ranger "for a year". Four years later I finally got it back, after my Lightning was t-boned and in the shop for two months. Still had the same oil change sticker up on the windshield corner. Four years and over 40,000 miles, and she never bothered to change the oil. Didn't hurt anything though. Doesn't leak or burn oil at soon to be 188,000 miles. So much for those much vaunted 3000 mile oil changes. But man, that oil was FUBAR!
