Ok, What have I done now... (904 problem?)

Ok for anyone still interested.... I fired the car up and pulled it out. I jacked it up and leveled it. I ran it for probably 45 mins to an hour in different gears. I added about another 3/4 liter in her a little at a time. Its now reading about 3/4" over the full line... I took it for a slow tour around the block and its shifting pretty much the same... real slow to switch gears... Slips thru neutral to high...

I cant add anymore... the level wont drop while running and shifting gear. All I can do is drop the pan and check for clearance under the filter... Its too cold to play tonight so I'll drop it tomorrow night...

I really hope I find that the filter is not correct, I really don't want to start the season by pulling the tranny out after everything was fine when it went away.

If anyone else has any suggestions I'd love to hear it...

Thanks
