Maybe try a Mack truck forum. This is Cummins territory here.

If you got facebook try the "volvotruckmasters" page they can atleast point you in the right direction.

The best way to fix a Mack especially after Volvo got involved is drop a roadflare between the seats and sit back and sip a nice cold refreshing beverage while you watch it repair itself.
