Problem
went threw it and found nothing wrong with ,so standard rebuild with all the goodies. and i still have same problem. he brought it back and the guys at aamco told him second gear was out. so i went threw it again and found nothing but it did have some codes 622 shift solenoid 2 ,512 KAM test fail. I cant erase them they keep coming back so i im looking threw the wires and the only wire i found that was pinched was the one for the trans range sensor . so i fixed it and now it seems to work good but i keep getting those same codes. help
