It has been on the jack stands for two weeks without starting, so a lot of fluid drained out.

Car only has 33k miles.

Put back 5-1/4 quarts, once up to temp at 104F, about 1/4 of a quart came back out of the standoff pipe.

Not a hard DIY, plan to do this again in 10K miles.

As JCHammond already said there's much more in the system that what is drained.

I followed the below theread, same sprayer, got a infrared temp. Gun from Harbor Freight for $20 and used Valv. Max Life without issue. Simply measure the trans temp. At the pan sump with the gun and at 104*'ish pull the full plug until fluid stops running out then replace. There's a standpipe at the hole so only the "overfill" is running out. If you want to go the extra mile pull the pan and clean the magnets off. Pan gaskets are available from whateverittakes.com. I did mine at 72k for the 1st time and it was nasty, did again 10k miles later and only drained the pan since it was like new. Proves JCHammonds technique gets all the bad fluid out.

Car shifts much smoother after the full flush and fill proving it's not a lifetime fill.
