Form in Ford F350 V8 Motor 7.3 Diesel

Hello I have a Ford F350 v8 7.3 diesel truck which blinks the over Drive light which does not also do not pass the 90kms and consume triple fuel.
If someone can guide me what the problem would be appreciated.

I also need the steering box and the hydraulic pump of this same truck and if possible the complete manual of it.

Greetings
