We sent our ZF 4wg-200 trans in to get rebuilt with a trans shop we've used in the past but the trans was in pretty rough shape and they want about $30,000 to rebuild it. I called this place in Illinois, Schaefer Enterprises and a place in Indiana, Component Service Inc. They are both salvage yards and they can both get us a rebuilt used trans with a 6 month warranty for $13,000 and the condition of the core does not matter so long as its all there. Just wondering if anyone had any experience with these places. Both these places are within driving distance for us so we wouldn't have to pay extra freight either.
