According to a website I found for decoding VINs, the 4th to 8th characters identify vehicle features, including the engine, transmission, etc. I have been unable to find any way to decode those characters. I found two Suzukis with identical characters in that block. One (the one I bought) had a manual transmission. The other, advertised as having a manual tranny, had an auto when I went to look at it. After that experience, I am not sure Suzuki puts that info in the VIN.
