Hi there,
Thank you for the donation,
The service fill is 4 quts, so the 6 may be too much, re check the level and correct to hot full mark, I would think that you have not done any real harm, the trans has had lubrication thats the important factor, if you have any worries get the trans tested at a specialist repaired they will do a line & shift pressure test that will give a better indication as to any problems that may be present.
