PCS help

Hey Guys,

I am in the final stretch of my 24v cummins conversion in my 96 OBS CCLB. I got my trans rebuilt, and engine also. I am using a calibration from auto world, but the issue seems to be that the trans is shifting, way to early, the other issue is that the vehicle speed is not matching what my GPS is telling me. I went through the initial set up wizard, and sent the calibration to the PCS, but it is not running normal, any thoughts?

Thanks guys.
