I was wondering if anyone else had this problem. Any ideas maybe add something to the oil?

Thanks

How much fluid came out and how much was put back in? How did they change it? If you did a power flush it is very possible that the trans is shocked and that is not good. You want to keep fluid change in a trans to under 50% if possible.
