I just got done rebuilding the 4t65eHD out of my new Grand Prix. I noticed that it does not shift into second, it just hits it on the way to 3rd for just a second. It doesn't matter what i do. When i got the car it wouldn't move at all (bad oil pump shaft) so i don't know if it was doing it before, but the 2nd gear clutches were toast. please help i'm moving in a week
