No trans fluid flow after change
I just changed the filters in my transmission and now I'm not getting any fluid out of the return line. When I drained it, I pulled the return line, started it, and pumped most of the fluid out of the pan. I replaced everything, put 5qt of fluid in to the cold line, and then tried to run it with the return line off again to flush more of the old fluid out, but I get nothing. I ran through gears but still have no fluid coming out of the return line. Is there a thermostat before it sends the fluid to the cooler? Except that it pumped out fine when I drained it cold. I'm guessing I messed up the seal for the filter. I tapped it in with a socked and made sure it was flush all the way around though. Any ideas?

Also, the screw in filter didn't screw in very nicely. It would get very snug at one point in its circle of screwing it in, then turn easy again. I think I got it screwed in tightly, but it may not be. Could that cause the issue? I'm guessing the filter is after the line I unhooked though and wouldn't matter.

Also make sure that the flat pan filter is installed correctly. The transmission pump feeds the torque converter by pumping fluid from the pan through that filter. Be sure that you kept the pan filter level as you pushed it in, while giving a slight of wiggle (push and wiggle simultaneously). The filter should not have moved at all when you put in the mounting screw. If the filter did move when putting in the screw, then the filter is cocked and the transmission pump will suck air.
