see if that smell is coming from your transmission from burning transmission fluid. You may want to get that transmission looked at and look at all the tranny posts on this forum. There is a solenoid or valve that sometimes goes bad on the tranny also. It's not that expensive to replace either--tranny stays on car. $80 valve + labor.
later edit:
more expensive than I thought:
