2003 Sprinter with 4 speed transmission

I hope to soon be a Sprinter owner and have a question about one that I am considering.
It is a 2003 with a 4 speed automatic transmission. I was unaware that they were available in a 4 speed. Is there anything I should be aware of with this transmission?

Thanks,
Dave

no 4 speed auto only 5 speed auto in na.
