Hello everyone, my car is jerking or hesitating everytime i get to 12mph. I guess that is when it goes to 2nd gear(automatic). I just changed the oil and had the fluids checked. Do you think that this is a computer problem. It feels like it is in nuetral and than jerks to the next gear. It has been happening for the last 3 monthes now and has been getting worse. it used to happen just every few days. now it happens everytime i hit 12mph. weird? thanks in advance
