4L60E trouble

I have a 97 c1500 with the vortech 350 and the 4l60e 2WD. I had the tranny rebuilt about 16 months ago and now it's giving me trouble. When i try to go forward in od it feels like my brakes are applied, but if i shift it down to 2nd it drives off ok. Any ideas? I have checked the fluid levels and it's fine. I have no leaks and once I'm moving it drives like normal. Please help me.

Sounds like a probelm in the 2nd gear circuit. Cracked or worn out accumilator or in the 2nd gear servo. By-passing oil to apply the band when it should not be applied.

You shift to 2 and the vehicle drives... shift to third gear the oil from 3rd gear forces the servo off... then in over drive the band is back applied
