It will have the 643 tranny.
How can you guess this by what info the OP has given you which is nothing. You don't even know the year. 99% of the buses don't have DT466 engines and a 643. My bus from Tennessee has a DT466 and the ever so wonderful AT545 transmission. There are many buses with the 444E.
To the OP, if someone that is 2000 miles away can't take the time to find out info that you want, I would pass on the bus. He doesn't have the only bus for sale.
