Found the issue with my "new" used trans. When installing the Transgo upgraded pressure relief valve spring I guess I didn't fully seat the snapring or didn't set it in the correct location. Checked the pressure port on the trans and only had 10 psi. Dropped the pan and there was my pressure relief valve train.
