that's 99% of the fluid and a new filter!
best by far method of changing the fluid.
a topsider will get about 60% of the fluid, and leave the debris and filter in the pan.

There was a recall in Australia about 30 years ago of GM trimatic transmissions because of filter degeneration. The bits of paper eventually find their way into the valve body & clutch packs & make a mess.

Taking the pan off is the only way to change the fluid.

Best just do it once, do it well !!!
