ABS has a lost communication with scanning tools. And the ABS malfunction light is on steady. And I think this is the reason why the transmission is not changing while driving.

You say 4-liter engine but there is no engine of that size. Can you tell me if you have a 5.3? I found these ABS wiring diagrams I think they are the ones you need.
