When I am slowing down my car jerks at twenty mph. I had a tune-up and transmission flush done.

the transmission flush may have disturbed some build up and a shift valve may be sticking, if it is not getting worse, i would let it go for a while and see if it clears it self, post back if it does not improve.sometimes a long drive to get the oil up to normal operating temp can help with sticking valves in the vale body
