From what I had been reading, I expected between 2-3 quarts to drain out... when I removed the drain bolt I stopped at 4 and it was still gushing out. Trans was room temp, and this was the factory fill.
got a 24mm socket from Lowes for $5 and went to work.
92,699 miles on "lifetime" fluid:
This stuff was black, I mean BLACK. I've done 10k OCI oil changes on a 93 civic with 300k and conventional oil that wasn't this black, how this is "lifetime" is insane.
New v.s Old....
I drained out exactly 4 quarts, then pumped back in exactly 4 quarts. I drove it for 10 miles through all gears, shifting was smooth as butter. There used to be a small bang when if shifted between 2nd and 3rd which is now gone, can't even tell when it's shifting now.
I just need to do the brake fluid (original lol) and I will probably just use the 1 person method with a bottle and some tubing. I did the serpentine belt in 5 minutes for $13, dealer wanted over $400, also did the spark plugs for $40 cause dealer wanted $570, I can only imagine brake fluid or an ATF drain and fill...
Good job. But i'm sure there's a lot more than 4 quarts of fluid in the transmission. Probably around 9-10. Do you plan on doing it again to make sure it's all in? The best way is to pump the old fluid out as new fluid is going in through the cooler lines.

I thought we didn't have cooler lines (sealed trans) ? yeah I will do it again at the next oil change, or the one after that if I'm lazy...then again a 3rd time. I was expecting around 2-3 quarts from the pan but 4 came out quick and it was still like a firehose when I put the drain plug back in to stop it
Here's a shot of the trans. That fluid has to be cooled somehow. Typically fluid will run through lines to an exchanger up front near the fans where air is moved.
At work we use valvoline max life in almost every conventional automatic transmission as per recommendations of the best transmission shop in town.
Never had an issue, multiple times it has gotten rid of shuddering and rough shifts and has always resulted in as good or better shift quality with no reduction in life span.
Put it in my dad's jeep after his cooler lines blew dumping all the fluid out, thought his tranny was toast but it's still working great months later even towing a sailboat!
just curious OP, why did you stop it at 4qrts? why not let it go until it stopped on its own?
I think he either dropped the pan or drained whatever came out of the bolt he removed. Much of the fluid is still probably in the torque converters, valve bodies, clutch pack, and lines. In other words everywhere except where the OP was draining from lol.
