Ford ZF S650 Six Speed Question

Question: I am interested in purchasing a 2006 Ford F550 with a 6.0 diesel, four wheel drive, ZF6 manual transmission, and a manual shift transfer case. The seller has stated that it will not go into 2nd or 3rd gear. I have not actually drove the truck, because it is further away than I can drive in a couple hours. Can you help me with options of repair and pricing? Maybe a repair manual?I am a carrier diesel mechanic with some experience rebuilding Eaton Fuller 5 and 6 speed manual transmissions, found in medium duty International trucks. And feel comfortable doing a rebuild on this transmission. But would appreciate some pointers to look for.
