It will fit. Control handles would be different. You have change those. You would need the Hydro cable you would be losing one cable because no need to shift. I put a 2 speed transmission out of a Hr214 sx in a Hr215 sx mower. The original 3 speed was trashed the pinion gear “is what I would call it”was worn down. I had the handle with the two speed controls so it was not a problem. If I had to buy that probably would not have done it. There was only one problem. It was to fast. Not sure if the RPMs of drive shaft going to trany was faster or what. 1st gear Was a little slower than what I would be comfortable with and in second you would need to almost jog. Someone looking at another mower I had thought it was to slow he bought it Loved the speed. He was about 6 ft 7inchs talll
