Car won't run past 60mph

Nope, you got it right. :D

Just so I understand that I may have it backwards. I thought at full throttle I should have full throttle pressure. This means that the throttle valve is pushed in the valve body all the way at full throttle. Is this not true? Please explain...where should the throttle pressure valve be at full throttle? I just put 8 quarts of fresh fluid in and still need at least another quart added before I test drive.
