2003 Subaru Legacy • 4 cylinder • 110,000 miles

Yesterday I had a friend drain my transmission fluid and put more in and replace the filter because there was shifting going on when my gears were changing. I drive a 2003 Subaru Legacy with an automatic transmission. The book said to put 9.8 quarts in, so we did. But we drained far less than that and today my check engine light is on and it smells like the fluid is burning and the shifting is still not fixed. Can you please help me with what I should do?

You have over filled it, that will be a dry re fill, not a service re fill, drain and correct fluid level, get a scan done and see what the fault code is, report that code here.
