The first mechanic's diagnosis was a bad transmission. But he only drove it around, didnt look inside. Second guy said that it was the transmission and some other things like torque converter. They replaced the fluid, cotter pin, torque converter, mainshaft, clutch drum, countershift drive nut, masinshaft drive nut, input shaft bearing, countershaft bearing, differential drive bearings and they got an automatic trans overhaul kit and used that(i dont know much about cars). They said that they found massive metal contamination and a worn 2/4 clutch drum. clutch drum on 4th gear broken retainer ring, and damaged all steel internal drive plates.
