OK new to this forum so I don't know how to post stuff just yet but my car is an automatic and sometimes when I stop it stalls out when I put it in reverse it hesitates then jerks into gear sometimes when I go to take off it will just rev up catch a gear jerk and go on when I'm on the highway at 75 or 80 mph it will seemingly come out of gear and redline then catch whatever gear its supposed to be in I've heard several different things it could be I cleaned the tps and mass air sensor and it wasn't doing it as bad then I got stuck the other night by accident and the problem came back even worse no check engine light or anything what could this problem be and what kind of advice or knowledge can be given here thanks
