Only if it was behind a diesel. The gas engines were lockups. But there were exceptions. I believe it could have been ordered either way or a GVWR was the deciding factor. In either case just finding a certain year isn't a determining factor. The only way to go by the year is if it was a diesel, which would be 91.5-93 intercooled models.
I will assume that even a diesel unit would work with a governor change and maybe changing the valve body to get the shift points up
