Ok so as recommended I searched for any leaks and the vehicle does not have any (I checked by ear, visually, and by the use of spray to see if car would react differently), I replaced the Vehicle speed sensors (rpm and speedometer), and I also cleaned off the mass air flow sensor. Along with that I also noticed that one of the o2 sensors had oil residue on it due to it being so close to the trans dipstick so I also cleaned that off using the QB electric cleaner. Last but not least I also replaced the Trans filter, gasket, and of course oil (the oil seemed as if it had not been replaced in a long time). The car drives and it does not shift properly (by this I mean that it does not always downshift on its own into first at a complete stop and it never shifts into 4th the final drive gear at all). I have driven about 15 miles and no codes reappear, I am going to continue driving a bit more to wait and see if any codes reappear. until then any more suggestions?
