It revs to 1700 before it shifts and splits every gear even when bobtailing. For now I just stick it in maual mode, that lets me shift around 1400 but it kinda defeats the purpose of an "automatic".

You can change the shift point calibration if you have Service Ranger software. Unfortunately though, you have to just do it by trial and error because in my experience, there's no explanation of the differences between all the choices.
