My 2002 Volkswagen 1.8t automatic starts at 2nd gear and doesn't change?

What is your question?

I drained out transmission fluid instead of the motor oil while I was doing an oil change. Ran it for about 20miles without fluid in the transmission. It started not passing 60mph and then it took a good amount of Rpms to get some speed. Did end up putting tranny oil but it still takes a bit to get some speed and now it starts and stays at 2nd gear. None of the gear shifts

What makes this problem better or worse?

Havent tried it
