Had my 727 built recently but it doesn't shift into second gear like it should. The trans guy said he would pull it back apart, but he isn't real sure what might be the problem. The trans shifted great going into second gear and slipped into third when I took it to him for a rebuild. When I got it back when I shift manually from first to second it shifts kind of odd and third is great. It doesn't really feel like it is slipping. When I shift to second it pulls the motor down and takes about to seconds for everything to catch up and it's good from there. When it shifts to second in normal driving it shifts fine. Driving down the road, kick in the passing gear and it will down shift to second great and haul butt. Could the band be too tight?
