I have a Craftsman riding mower in the shop (917.275351) that has a Dana/Spicer transaxle gone bad. It still drives, but the input shaft has worn out the hole in the upper housing. Replacement 6 speed transaxle is NLA, so are most of the parts. I'm thinking I may be able to get by with a used one from ebay. The model number of the transaxle is 4360-140. There are lots of 4360 transaxles I see online, but will they fit this mower? Those of you with more experience swapping rear ends would know more about this than me.
I also saw an upper housing (5305) for sale, and it looks good. But I'm not sure that's the same as the 5305T which shows up in the parts description when I put in the upper housing part number (170981).
I think this thing can be fixed, but I don't know enough about the interchangeability of parts between different models.
