700R4 help

[Jay84SS]

I just rebuilt my 700R4 Billet servos .500 boost valve low and res. boost valve and trans go 2-3 shift kit. I have rebuilt a few 700's before but they were all stock app. i followed the trans go shift kit instructions for the auto setup where you can manual shift it or just put it in drive. Ever since i put the shift kit in it will not shift out of second when it tries to go into 3rd it like it's in neutral and then you coast and then it will down shift back to second when you have slowed down enough any help and or idea would be great.





Thanks Jonathan
