Volvo service manual calls for 30 minutes of highway driving before checking the Hot mark.

thanks bergmjs. this is good to know. and i trust vadis. i know some mechanics and that is why they are dubbed "experts" and why they make those manuals & recommends. knowing is only half the battle though...GI Joe...

Plenty of people have found mistakes in VADIS too. Nothing's perfect. I did recently read about a case study done to try and trick people. Open-crowd internet conversation quickly ironed out the lie, thanks to the amount of people (And diverse group) looking at the data. So, conclusion, VS is your best source of info

Pretty sure that as part of the goal of driving around to heat up the ATF, you want to shift through all gears. It's pretty unlikely you could pull off 30 minutes of driving without reaching 4th, but just putting that out there. Don't forget to measure on a flat surface. Also, it really doesn't matter what quantity you are supposed to drain/fill. Just drain and MEASURE it as it comes out. I bought a 2.5gal water jug, marked it every quart on the side and use that to measure it as it comes out. I pump out 3qt at a time, shut down, fill, repeat. Also eliminates the need to mess with the drain plug.

As for the above issue, personally, I would just keep it in drive and not put it in neutral is it's not needed.

Isn't that like telling the doc "it hurts when I poke my stomach here" and he says don't poke there? Ya, no shit but its still a potential symptom. I put my car in N to coast all over the place, sometimes forgetting to put it back in D when the light turns green, and I've never felt the car do anything besides momentum/gravity. Next time I'm out I'll try what you're talking about but pretty that shouldn't happen. I wonder if its something goofy about the engine rotating from being revved and giving your car a gentle "push" of energy.

interesting stuff there fudge brownie. the most important thing i take from your post being that Vadis is, in fact, authoritative or expert source. as for the rest, it was difficult to follow for me. but then again, i'm a flake.

so if i am reading your post right fudgebrownie: its safe to shift into neutral outside of Park/standstill? i never tried this and i always wondered about it but...

any chance to save fluid or save wear/tear seems like it would be worthwhile...but of course this is common sense speaking and i wouldnt want to shake the status quo by making sense.

My sentence structure is infamously poor and needlessly complex. My fault, not yours.

The thing about 'crowd sourcing' was a complete tangent that is 100% irrelevant, and I was partially kidding around anyway. I shouldn't have included it. VADIS was the authoritative resource for Volvo dealerships, however I think it's now a different name/software (VIDA?).

You can shift an automatic in to N while driving. Remove your foot from the gas, shift to N. You can slip it right back in to D as well. Be extremely careful not to slip it in to R. You'll find the selector allows you to go between N and D without pressing the button, but requires the button to enter R. Great for coasting down long hills, you'll find it relieves a surprising amount of drivetrain drag. I've never once seen anything official saying this practice is acceptable/safe. But I know plenty people do it. You can search here and I'm pretty sure there's a few threads about it. Pretty sure shifting is what really builds heat in an automatic transmission, so hypothetically, shifting to N and back to D frequently could build extra heat, which burns up ATF quicker.
