Automatic transmission 1998 Subaru Forester. I drained the fluid and put new in. Now it is full to the top of the dip stick spout but acts like it isn't getting down to the pan.

Did you drop the pan to change the filter? if you drained the fluid and you can get the stick into the tube all the way. i would say the tube is not clogged. you should know how much you took out and the trany only holds so much. check the manual for the correct type and amount. if the fluid is over full that is a problem and will need to remove some. when i add fluid i put in a couple quarts and start the car and cycle the fluid only a couple seconds 15 to 30 not mins or hours the turn off add another till i think its close to what i took out. start car cycle some more repeat till you think your close within a quart to being full. at that point you can keep the car ruuning and check the fluid and keep checking the mark on the stick. if it wont go down the tube. you may have something blocking the tube and removing the pan again or tube to see whats blocking the tube is your only option.
