Well now we have some more information. I can't answer for the valve body but like TRENDZ says a normal 518 will not allow OD until it's in 3rd gear. Maybe, possibly, the transgo modifications allow this. This could possibly have done some damage, I don't know.
Mike, did you take the OD unit apart when you dealt with the governor valve? I have seen the small bushing between the intermediate and output shafts crack and break into small pieces. This could possibly be jamming the inner race of the over running clutch.
No we didnt take the OD apart.. we put in a new/used unit
EDIT
I took the day off and went fishing so tomorrow I'll take it
out on the road and see if the OD works in 1st and 2nd and I'll
check the wiring
