My automatic transmission is leaking…

Hello! I’m new here in the forum, but I’m in similar live! Of course I’ve looked around here before and have to say how to deal with each other – that’s exactly mine – that’s what I like! And also the tips! – so well described – will now also dump 2T oil into the tank *ggggg* But now to my (large) problem: I had my transmission oil changed back then (November 2005) (automatic) Well, the workshops (it’s already 2) won’t keep the whole thing tight anymore. Now there’s a new tub (the big one) on it, a new seal, new screws …everything is new, but it’s still getting a little oil out. What should I do now? Tell me my (biger) board computer what if the oil level in the gearbox becomes too low? Can it be that the transmission somehow got damaged? Which messages does the automatic transmission bring… I’m really desperate, because it’s been pulling away now since March … I hope it’s not going to be expensive, because I’ll soon father and need every cent, however, I want to keep the Omega, because I love it!
