Thump-A-Thump
As the saga continues: I recently changed the transmission fluid and filter per directions. The old fluid was nearly a dark burgundy color. Everything went great until I started driving the car. Smooth going up the gears but at about 10 mph slowing it gives a good thump-a-thump that wasn't there previously. I've tried searching but can't find anything relevant. Did I do something when I changed the fluid/filter? Any thoughts would be of great help.

Did you happen to check the level before you drained the old fluid? Was it still full? And when you filled it up did you start the engine after topping it off, run it through the gears and then proceed to top it off again with the engine still running? Have you checked the fluid with the motor running and at operating temp since the drain and fill to make sure it's still full?

I would get under there ASAP to double check the fill level and have a good look around. Of all my searching on tranny issues the past several weeks, I did not come across one thread in regard to your individual situation. If everything checks out, the only thing you can do is pull the pan again and see where you went wrong, since this problem was not there prior to you molesting it.

Just me thinking out loud... If the filter isn't sealed where it mounts on the sump (o-ring) or the pick up tube attaches to the filter (o-ring), could the sump be drawing in air along with the fluid causing the frothiness?

I hadn't refreshed the page when I wrote my response after dinner to see you had the same thought.

Went for a ride and came back and rechecked(was not frothy).
