Default 4L60E not going into 2nd under wot

Hey there,

I just had my trans rebuilt but it didn't fix my full throttle 1st to 2nd shift. Does anyone know what this could be. Mechanic is looking into it now.

Thank you

Yeah I replaced that before. Didn't help. And he's tried that too. He's checking PCM and Maf.
