From my understanding, the BJ60 (3B natural aspirated) and HJ61 (2H natural aspirated) were only offered with the 5spd outside of the US(I think). I don't believe that any of the diesels came with a 4spd.
BJ60's up thru 83? had 4 speeds, I'm thinking HJ's also did as the 5 speed wasn't available until then. I know as I have one, I think it was from an 82 or 83 BJ60.
