You need to get that oil out of there right away, especially if it has a burnt smell. Change the filter and gasket at the same time and pay attention to what comes out of the oil pan when you do this. Filings in the trans oil are normal wear and tear but pieces aren't. Add a bottle of a trans additive to extend life, I've had good luck with Lucas. If the trans is still acting up you will have to start looking for a replacement although you can add a second bottle of Lucas, if that is what you use, to help get you by until you can repair properly. Hope this helps.
