2023 Genesis G70 — service lifetime transmission fluid or leave it alone?

Start with the test that can prove you wrong. A pressure test beats staring at a dry driveway if the 2023 Genesis G70 is losing coolant with no puddle. If the cheap test changes it, stop and reassess. I'd want that in writing, not as a promise. Your commute and mine probably aren't the same, but the test still applies. I already checked the easy fluid levels.

If it were in my driveway, a pressure test beats staring at a dry driveway if the 2023 Genesis G70 is losing coolant with no puddle. Save the big job until that test fails. Learned this the expensive way on a previous car. Heat soak after errands is the other window.

I'd want a measurement, not a hunch. Write temp, speed, and in-gear vs coast when the 2023 Genesis G70 does it — then decide on parts. You'll know quickly if you're on the wrong tree. This is from a 2023 Genesis G70 in San Antonio with 40,000 miles. I'd want a dollar figure or a measured spec, not 'should be fine.' Not trying to scare you — just skip the expensive first guess. If the story changes I'll post the new data.
