Yes it does. You have to remove the transmission pan and the filter is located inside and mounted to the transmission with two or three bolts. I have a 1995 Avalon and I just replaced my fluids and transmission filter. Pretty easy job.
In the transmission pan
it is underneath the air filter bolted to the firewall on the driverside of the car
There is a screen in the transmission fluid sump but no filter.

The filter is located inside the transmission just inside the bottom pan.
