My wife's car is a 2006 FWD and has 113k miles now and it was time to change the tranny filter. I did a drain and fill using 4 qts at 80k miles. Plenty of DIY out there for just drain and fill for tranny fluid so I will skip most of the basics.
Below is my experience in doing this. I would rate it on a scale of 1-10 with 10 being most difficult probably a 4 only because there a 4 bolts on the tranny pan (driver's side) that are really difficult to access. Total time is ~3hrs.

5 quarts type IV toyota fluid
10mm ratchet wrench
tranny pan gasket - can buy on Rock Auto or ebay
tranny filter with o-ring (I bought a Wix brand filter, it came with O ring) - can buy on Rock Auto or ebay
As you can see the Wix is a paper filter
Drain plug (allen wrench needed)
The next two pics - I was trying to show some of the tranny pan bolts that are buried closely to the frame of the vehicle on the driver's side. This is where you need the ratchet wrench
once the plug is loosened fluid start to flow freely
I made sure to catch all fluid in a tray or pan so I could measure it later and replace with the exact amount that came out
Fluid is not bad - still bright red
Now on to the pan. Most bolts are easy access except 4 on the driver's side. You cannot get a basic socket set to them, so here is the adjustable ratchet wrench I used. And worked from above the frame.
Here you can see the relationship between the frame and the pan. Work above the frame. It also may be easier to remove your front driver's wheel/tire. One of the bolts next to the engine mount is a real pain in the ****.
Once I loosened all the bolts and pulled the pan, it is pretty dirty
So are the magnets...
All clean. I replaced the gasket as well. I would suggest going ahead and putting bolts in the pan at all four corners BEFORE you reinstall to help hold the gasket. It does not lay flat like the old one (look at first picture above). This helps keep in place.
Now to the filter. 3 bolts, all 10m. They are not tight.
***Be careful here. Another half quart of fluid comes out once filter is removed!***
Look at the difference between old and new - filthy. The old filter was covered in metal shavings, similar to the magnets.
Here, I am measuring the old fluid into a used 5 quart oil jug.
EXACTLY 4.5 quarts. This is what I replaced. Had some splash spillage when I removed the pan, but I still put 4.5 qt in and will check level later tomorrow.
Put everything back together the reverse it came off. Do NOT overtighten! I think the filter bolts are only 8lb ft of torque. Just snug up the pan bolts. Trick: work one side to the other. tighten a bolt in one corner then work your way to the other corner. Or start on one side then the other.
Need skinny funnel for the dipstick tube for new fluid.
Add new fluid.
Hope this helps.
