I have a '97 LS with a floor shifter. I've seen other LS models that have a column shifter. I personally prefer the floor version but I often wondered why GM had 2 locations for it.
Was the floor shifter an option that year even though all blazers have that center console. Or was there more than one tranny option?
I've always been with the impression that all Blazers shared the same 4L60 tranny.

 

The floor shifter was an option. Same 4L60E transmission.
