I have a 2001 dodge ram 1500 46re transmission. First the trans oil pan gasket blew so i changed that and the filter. No debris in the pan what so ever. Filled it back up with Atf +4. Everything was correct. Then i went to start it and it wouldnt start in park. So i changed out the neutral safety switch and the problem was fixed. Tried to drive it and it wouldnt move. So next i changed out the governor pressure solenoid/sensor. The car drives now but it slips in third gear and sometimes from 1st to 2nd. There is also a hard jerk from a stop to go. Should i adjust the bands? What else could be the problem. I also cleaned out the IAC for some reving problems and it fixed them. The truck has 70000 miles on it. Any help would be appreciated.
