nah man if the car is like jumpy when u come to a stop at times... like it moves when ur on the breaks n shit..... and then when you stop and go... it doesnt shift then your problem is the tranny itself not the tranny fluid.... check the fluid just incase but its happened to me as well.... i had my car shifting weird as fuck... and sometimes it would get stuck in 5th and not lower when breaking etc... so i had to get a new tranny n shit..... but realistically its something with the tranny....
